- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) 19yy <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) 19yy name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-This is the README file for the "extras" library, consisting of Pd
-objects which are too specialized or otherwise non-canonical for
-inclusion into Pd proper. These files are open source; see
-LICENSE.txt in this distribution for details.
-Note however that "expr" is GPL (the rest is all BSD).
-
-This package should run in Pd under linux, MSW, or Mac OSX.
-You can additionally compile fiddle~. bonk~, and paf~ for Max/MSP.
-
-contents:
-
-externs:
-fiddle~ -- pitch tracker
-bonk~ - percussion detector
-choose - find the "best fit" of incoming vector with stored profiles
-paf~ -- phase aligned formant generator
-loop~ -- sample looper
-expr -- arithmetic expression evaluation (Shahrokh Yadegari)
-pique - fft-based peak finder
-lrshift~ - left or right shift an audio vector
-
-abstractions:
-hilbert~ - Hilbert transform for SSB modulation
-complex-mod~ - ring modulation for complex (real+imaginary) audio signals
-rev1~, etc. - reverberators
-
-These objects are part of the regular Pd distribution as of Pd version
-0.30. Macintosh versions of fiddle~, bonk~, and paf~ are available

-(provided as a list of 11 numbers giving the signal "loudness" in the

-an instrument number (counting up from zero) and a "velocity". This

-1 The instrument number is significant only if Bonk has a "template
-set" in memory.;

- GNU LESSER GENERAL PUBLIC LICENSE
- Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
- This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
- 0. Additional Definitions.
-
- As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
- "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
- An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
- A "Combined Work" is a work produced by combining or linking an
-Application with the Library. The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
- The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
- The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
- 1. Exception to Section 3 of the GNU GPL.
-
- You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
- 2. Conveying Modified Versions.
-
- If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
- a) under this License, provided that you make a good faith effort to
- ensure that, in the event an Application does not supply the
- function or data, the facility still operates, and performs
- whatever part of its purpose remains meaningful, or
-
- b) under the GNU GPL, with none of the additional permissions of
- this License applicable to that copy.
-
- 3. Object Code Incorporating Material from Library Header Files.
-
- The object code form of an Application may incorporate material from
-a header file that is part of the Library. You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
- a) Give prominent notice with each copy of the object code that the
- Library is used in it and that the Library and its use are
- covered by this License.
-
- b) Accompany the object code with a copy of the GNU GPL and this license
- document.
-
- 4. Combined Works.
-
- You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
- a) Give prominent notice with each copy of the Combined Work that
- the Library is used in it and that the Library and its use are
- covered by this License.
-
- b) Accompany the Combined Work with a copy of the GNU GPL and this license
- document.
-
- c) For a Combined Work that displays copyright notices during
- execution, include the copyright notice for the Library among
- these notices, as well as a reference directing the user to the
- copies of the GNU GPL and this license document.
-
- d) Do one of the following:
-
- 0) Convey the Minimal Corresponding Source under the terms of this
- License, and the Corresponding Application Code in a form
- suitable for, and under terms that permit, the user to
- recombine or relink the Application with a modified version of
- the Linked Version to produce a modified Combined Work, in the
- manner specified by section 6 of the GNU GPL for conveying
- Corresponding Source.
-
- 1) Use a suitable shared library mechanism for linking with the
- Library. A suitable mechanism is one that (a) uses at run time
- a copy of the Library already present on the user's computer
- system, and (b) will operate properly with a modified version
- of the Library that is interface-compatible with the Linked
- Version.
-
- e) Provide Installation Information, but only if you would otherwise
- be required to provide such information under section 6 of the
- GNU GPL, and only to the extent that such information is
- necessary to install and execute a modified version of the
- Combined Work produced by recombining or relinking the
- Application with a modified version of the Linked Version. (If
- you use option 4d0, the Installation Information must accompany
- the Minimal Corresponding Source and Corresponding Application
- Code. If you use option 4d1, you must provide the Installation
- Information in the manner specified by section 6 of the GNU GPL
- for conveying Corresponding Source.)
-
- 5. Combined Libraries.
-
- You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
- a) Accompany the combined library with a copy of the same work based
- on the Library, uncombined with any other library facilities,
- conveyed under the terms of this License.
-
- b) Give prominent notice with the combined library that part of it
- is a work based on the Library, and explaining where to find the
- accompanying uncombined form of the same work.
-
- 6. Revised Versions of the GNU Lesser General Public License.
-
- The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
- Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
- If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-New in Version 0.3
--Full function functionality
-
-------------
-
-The object "expr" is used for expression evaluaion of control data.
-
-Expr~ and fexpr~ are extentions to the expr object to work with vectors.
-The expr~ object is designed to efficiently combine signal and control
-stream processing by vector operations on the basis of the block size of
-the environment.
-
-fexpr~ object provides a flexible mechanism for building FIR and
-IIR filters by evaluating expressions on a sample by sample basis
-and providing access to prior samples of the input and output audio
-streams. When fractional offset is used, fexpr~ uses linear interpolation
-to determine the value of the indexed sample. fexpr~ evaluates the
-expression for every single sample and at every evaluation previous
-samples (limited by the audio vector size) can be accessed. $x is used to
-denote a singnal input whose samples we would like to access. The syntax
-is $x followed by the inlet number and indexed by brackets, for example
-$x1[-1] specifies the previous sample of the first inlet. Therefore,
-if we are to build a simple filter which replaces every sample by
-the average of that sample and its previous one, we would use "fexpr~
-($x1[0]+$x1[-1])/2 ". For ease of when the brackets are omitted, the
-current sample is implied, so we can right the previous filter expression
-as follows: " fexpr~ ($x1+$x1[-1])/2". To build IIR filters $y is used
-to access the previous samples of the output stream.
-
-The three objects expr, expr~, and fexpr~ are implemented in the same object
-so the files expr~.pd_linux and fexpr~.pd_linux are links to expr.pd_linux
-This release has been compiled and tested on Linux 6.0.
-
---------
-
-Here are some syntax information: (refer to help-expr.pd for examples)
-
-Syntyax:
-The syntax is very close to how expression are written in
-C. Variables are specified as follows where the '#' stands
-for the inlet number:
-$i#: integer input variable
-$f#: float input variable
-$s#: symbol input variable
-
-Used for expr~ only:
-$v#: signal (vector) input (vector by vector evaluation)
-
-Used for fexpr~ only:
-$x#[n]: the sample from inlet # indexed by n, where n has to
- satisfy 0 => n >= -vector size,
- ($x# is a shorthand for $x#[0], specifying the current sample)
-
-$y#[n]: the output value indexed by n, where n has to
- satisfy 0 > n >= -vector size,
- $y[n] is a shorthand for $y1[n]
-
-
-I'll appreciate hearing about bugs, comments, suggestions, ...

- * where x is either i(integers), f(floats), and s(strings); and #
- * is a digit that coresponds to the inlet number. The string variables
- * can be used as strings when they are quoted and can also be used as
- * table names when they are followed by "[]".
- *
- * signal vectors have been added to this implementation:
- * $v# denotes a signal vector
- * $x#[index] is the value of a sample at the index of a the signal vector
- * $x# is the shorthand for $x#[0]
- * $y[index] is the value of the sample output at the index of a the

-/* "expr" was written by Shahrokh Yadegari c. 1989. -msp
- *
- * Nov. 2001 --sdy
- * conversion for expr~
- *
- * Jan, 2002 --sdy
- * added fmod()
- *
- * May 2002
- * added floor and ceil for expr -- Orm Finnendahl
- *
- * July 2002 --sdy
- * added the following math funtions:
- * cbrt - cube root
- * erf - error function
- * erfc - complementary error function
- * expm1 - exponential minus 1,
- * log1p - logarithm of 1 plus
- * isinf - is the value infinite,
- * finite - is the value finite
- * isnan -- is the resut a nan (Not a number)
- * copysign - copy sign of a number
- * ldexp - multiply floating-point number by integral power of 2
- * imodf - get signed integral value from floating-point number
- * modf - get signed fractional value from floating-point number
- * drem - floating-point remainder function
- *
- * The following are done but not popular enough in math libss
- * to be included yet
- * hypoth - Euclidean distance function
- * trunc
- * round
- * nearbyint -

- * vexp_func.c -- this file include all the functions for vexp.
- * the first two arguments to the function are the number
- * of argument and an array of arguments (argc, argv)
- * the last argument is a pointer to a struct ex_ex for
- * the result. Up do this point, the content of the
- * struct ex_ex that these functions receive are either
- * ET_INT (long), ET_FLT (t_float), or ET_SYM (char **, it is
- * char ** and not char * since NewHandle of Mac returns
- * a char ** for relocatability.) The common practice in
- * these functions is that they figure out the type of their
- * result according to the type of the arguments. In general
- * the ET_SYM is used an ET_INT when we expect a value.
- * It is the users responsibility not to pass strings to the
- * function.

-size \, the maximum polyphony (i.e. \, the number of simultaneous "pitches"
-to try to find) \, the number of peaks in the spectrum to consider
-\, and the number of peaks \, if any \, to output "raw." The outlets
-give discrete pitch (a number) \, detected attacks in the amplitude
-envelope (a bang) \, one or more voices of continuous pitch and amplitude
-\, overall amplitude \, and optionally a sequence of messages with
-the peaks.;
-#X text 8 296 The analysis hop size is half the window size so in the
-example shown here \, one analysis is done every 512 samples (11.6
-msec at 44K1) \, and the analysis uses the most recent 1024 samples
-(23.2 msec at 44K1). The minimum frequency that Fiddle will report

- * Fiddle is a pitch tracker hardwired to have hop size ("H") equal to
- * half its window size ("N").
- *
- * This version should compile for Max "0.26," JMAX, Pd, or Max/MSP.
- *
- * The "lastanalysis" field holds the shifted FT of the previous H
- * samples. The buffer contains in effect points 1/2, 3/2, ..., (N-1)/2
- * of the DTFT of a real vector of length N, half of whose points are zero,
- * i.e., only the first H points are used. Put another way, we get the
- * the odd-numbered points of the FFT of the H points, zero padded to 4*H in
- * length. The integer points 0, 1, ..., H-1
- * are found by interpolating these others, using the fact that the
- * half-integer points are band-limited (they only have positive frequencies.)
- * To facilitate the interpolation the "lastanalysis" buffer contains
- * FILTSIZE extra points (1/2-FILTSIZE, ..., -1/2) at the beginning and
- * FILTSIZE again at the end ((N+1)/2, ..., FILTSIZE+(N-1)/2). The buffer
- * therefore has N+4*FILTSIZE floating-point numbers in it.
- *
- * after doing this I found out that you can just do a real FFT
- * of the H new points, zero-padded to contain N points, and using a similar
- * but simpler interpolation scheme you can still get 2N points of the DTFT
- * of the N points. Jean Laroche is a big fat hen.

-#X text 231 37 The creation arguments (level \, liveness \, crossover
-frequency \, HF damping) may also be supplied in four inlets as shown.
-The "liveness" (actually the internal feedback percentage) should be
-100 for infinite reverb \, 90 for longish \, and 80 for short. The
-crossover frequency and HF damping work together: at frequencies above
-crossover \, the feedback is diminished by the "damping" as a percentage.
-So zero HF damping means equal reverb time at all frequencies \, and
-100% damping means almost nothing above the crossover frequency gets
-through.;

-#X text 236 56 The creation arguments (level \, liveness \, crossover
-frequency \, HF damping) may also be supplied in four inlets as shown.
-The "liveness" (actually the internal feedback percentage) should be
-100 for infinite reverb \, 90 for longish \, and 80 for short. The
-crossover frequency and HF damping work together: at frequencies above
-crossover \, the feedback is diminished by the "damping" as a percentage.
-So zero HF damping means equal reverb time at all frequencies \, and
-100% damping means almost nothing above the crossover frequency gets
-through.;

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) 19yy <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) 19yy name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-This is the README file for the "extras" library, consisting of Pd
-objects which are too specialized or otherwise non-canonical for
-inclusion into Pd proper. These files are open source; see
-LICENSE.txt in this distribution for details.
-Note however that "expr" is GPL (the rest is all BSD).
-
-This package should run in Pd under linux, MSW, or Mac OSX.
-You can additionally compile fiddle~. bonk~, and paf~ for Max/MSP.
-
-contents:
-
-externs:
-fiddle~ -- pitch tracker
-bonk~ - percussion detector
-choose - find the "best fit" of incoming vector with stored profiles
-paf~ -- phase aligned formant generator
-loop~ -- sample looper
-expr -- arithmetic expression evaluation (Shahrokh Yadegari)
-pique - fft-based peak finder
-lrshift~ - left or right shift an audio vector
-
-abstractions:
-hilbert~ - Hilbert transform for SSB modulation
-complex-mod~ - ring modulation for complex (real+imaginary) audio signals
-rev1~, etc. - reverberators
-
-These objects are part of the regular Pd distribution as of Pd version
-0.30. Macintosh versions of fiddle~, bonk~, and paf~ are available

- GNU LESSER GENERAL PUBLIC LICENSE
- Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
- This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
- 0. Additional Definitions.
-
- As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
- "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
- An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
- A "Combined Work" is a work produced by combining or linking an
-Application with the Library. The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
- The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
- The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
- 1. Exception to Section 3 of the GNU GPL.
-
- You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
- 2. Conveying Modified Versions.
-
- If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
- a) under this License, provided that you make a good faith effort to
- ensure that, in the event an Application does not supply the
- function or data, the facility still operates, and performs
- whatever part of its purpose remains meaningful, or
-
- b) under the GNU GPL, with none of the additional permissions of
- this License applicable to that copy.
-
- 3. Object Code Incorporating Material from Library Header Files.
-
- The object code form of an Application may incorporate material from
-a header file that is part of the Library. You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
- a) Give prominent notice with each copy of the object code that the
- Library is used in it and that the Library and its use are
- covered by this License.
-
- b) Accompany the object code with a copy of the GNU GPL and this license
- document.
-
- 4. Combined Works.
-
- You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
- a) Give prominent notice with each copy of the Combined Work that
- the Library is used in it and that the Library and its use are
- covered by this License.
-
- b) Accompany the Combined Work with a copy of the GNU GPL and this license
- document.
-
- c) For a Combined Work that displays copyright notices during
- execution, include the copyright notice for the Library among
- these notices, as well as a reference directing the user to the
- copies of the GNU GPL and this license document.
-
- d) Do one of the following:
-
- 0) Convey the Minimal Corresponding Source under the terms of this
- License, and the Corresponding Application Code in a form
- suitable for, and under terms that permit, the user to
- recombine or relink the Application with a modified version of
- the Linked Version to produce a modified Combined Work, in the
- manner specified by section 6 of the GNU GPL for conveying
- Corresponding Source.
-
- 1) Use a suitable shared library mechanism for linking with the
- Library. A suitable mechanism is one that (a) uses at run time
- a copy of the Library already present on the user's computer
- system, and (b) will operate properly with a modified version
- of the Library that is interface-compatible with the Linked
- Version.
-
- e) Provide Installation Information, but only if you would otherwise
- be required to provide such information under section 6 of the
- GNU GPL, and only to the extent that such information is
- necessary to install and execute a modified version of the
- Combined Work produced by recombining or relinking the
- Application with a modified version of the Linked Version. (If
- you use option 4d0, the Installation Information must accompany
- the Minimal Corresponding Source and Corresponding Application
- Code. If you use option 4d1, you must provide the Installation
- Information in the manner specified by section 6 of the GNU GPL
- for conveying Corresponding Source.)
-
- 5. Combined Libraries.
-
- You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
- a) Accompany the combined library with a copy of the same work based
- on the Library, uncombined with any other library facilities,
- conveyed under the terms of this License.
-
- b) Give prominent notice with the combined library that part of it
- is a work based on the Library, and explaining where to find the
- accompanying uncombined form of the same work.
-
- 6. Revised Versions of the GNU Lesser General Public License.
-
- The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
- Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
- If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-New in Version 0.3
--Full function functionality
-
-------------
-
-The object "expr" is used for expression evaluaion of control data.
-
-Expr~ and fexpr~ are extentions to the expr object to work with vectors.
-The expr~ object is designed to efficiently combine signal and control
-stream processing by vector operations on the basis of the block size of
-the environment.
-
-fexpr~ object provides a flexible mechanism for building FIR and
-IIR filters by evaluating expressions on a sample by sample basis
-and providing access to prior samples of the input and output audio
-streams. When fractional offset is used, fexpr~ uses linear interpolation
-to determine the value of the indexed sample. fexpr~ evaluates the
-expression for every single sample and at every evaluation previous
-samples (limited by the audio vector size) can be accessed. $x is used to
-denote a singnal input whose samples we would like to access. The syntax
-is $x followed by the inlet number and indexed by brackets, for example
-$x1[-1] specifies the previous sample of the first inlet. Therefore,
-if we are to build a simple filter which replaces every sample by
-the average of that sample and its previous one, we would use "fexpr~
-($x1[0]+$x1[-1])/2 ". For ease of when the brackets are omitted, the
-current sample is implied, so we can right the previous filter expression
-as follows: " fexpr~ ($x1+$x1[-1])/2". To build IIR filters $y is used
-to access the previous samples of the output stream.
-
-The three objects expr, expr~, and fexpr~ are implemented in the same object
-so the files expr~.pd_linux and fexpr~.pd_linux are links to expr.pd_linux
-This release has been compiled and tested on Linux 6.0.
-
---------
-
-Here are some syntax information: (refer to help-expr.pd for examples)
-
-Syntyax:
-The syntax is very close to how expression are written in
-C. Variables are specified as follows where the '#' stands
-for the inlet number:
-$i#: integer input variable
-$f#: float input variable
-$s#: symbol input variable
-
-Used for expr~ only:
-$v#: signal (vector) input (vector by vector evaluation)
-
-Used for fexpr~ only:
-$x#[n]: the sample from inlet # indexed by n, where n has to
- satisfy 0 => n >= -vector size,
- ($x# is a shorthand for $x#[0], specifying the current sample)
-
-$y#[n]: the output value indexed by n, where n has to
- satisfy 0 > n >= -vector size,
- $y[n] is a shorthand for $y1[n]
-
-
-I'll appreciate hearing about bugs, comments, suggestions, ...

- * where x is either i(integers), f(floats), and s(strings); and #
- * is a digit that coresponds to the inlet number. The string variables
- * can be used as strings when they are quoted and can also be used as
- * table names when they are followed by "[]".
- *
- * signal vectors have been added to this implementation:
- * $v# denotes a signal vector
- * $x#[index] is the value of a sample at the index of a the signal vector
- * $x# is the shorthand for $x#[0]
- * $y[index] is the value of the sample output at the index of a the

- * the first two arguments to the function are the number
- * of argument and an array of arguments (argc, argv)
- * the last argument is a pointer to a struct ex_ex for
- * the result. Up do this point, the content of the
- * struct ex_ex that these functions receive are either
- * ET_INT (long), ET_FLT (t_float), or ET_SYM (char **, it is
- * char ** and not char * since NewHandle of Mac returns
- * a char ** for relocatability.) The common practice in
- * these functions is that they figure out the type of their
- * result according to the type of the arguments. In general
- * the ET_SYM is used an ET_INT when we expect a value.
- * It is the users responsibility not to pass strings to the
- * function.

-give discrete pitch (a number) \, detected attacks in the amplitude
-envelope (a bang) \, one or more voices of continuous pitch and amplitude
-\, overall amplitude \, and optionally a sequence of messages with
-the peaks.;

- * Fiddle is a pitch tracker hardwired to have hop size ("H") equal to
- * half its window size ("N").
- *
- * This version should compile for Max "0.26," JMAX, Pd, or Max/MSP.
- *
- * The "lastanalysis" field holds the shifted FT of the previous H
- * samples. The buffer contains in effect points 1/2, 3/2, ..., (N-1)/2
- * of the DTFT of a real vector of length N, half of whose points are zero,
- * i.e., only the first H points are used. Put another way, we get the
- * the odd-numbered points of the FFT of the H points, zero padded to 4*H in
- * length. The integer points 0, 1, ..., H-1
- * are found by interpolating these others, using the fact that the
- * half-integer points are band-limited (they only have positive frequencies.)
- * To facilitate the interpolation the "lastanalysis" buffer contains
- * FILTSIZE extra points (1/2-FILTSIZE, ..., -1/2) at the beginning and
- * FILTSIZE again at the end ((N+1)/2, ..., FILTSIZE+(N-1)/2). The buffer
- * therefore has N+4*FILTSIZE floating-point numbers in it.
- *
- * after doing this I found out that you can just do a real FFT
- * of the H new points, zero-padded to contain N points, and using a similar
- * but simpler interpolation scheme you can still get 2N points of the DTFT
- * of the N points. Jean Laroche is a big fat hen.

-#X text 231 37 The creation arguments (level \, liveness \, crossover
-frequency \, HF damping) may also be supplied in four inlets as shown.
-The "liveness" (actually the internal feedback percentage) should be
-100 for infinite reverb \, 90 for longish \, and 80 for short. The
-crossover frequency and HF damping work together: at frequencies above
-crossover \, the feedback is diminished by the "damping" as a percentage.
-So zero HF damping means equal reverb time at all frequencies \, and
-100% damping means almost nothing above the crossover frequency gets
-through.;

-#X text 236 56 The creation arguments (level \, liveness \, crossover
-frequency \, HF damping) may also be supplied in four inlets as shown.
-The "liveness" (actually the internal feedback percentage) should be
-100 for infinite reverb \, 90 for longish \, and 80 for short. The
-crossover frequency and HF damping work together: at frequencies above
-crossover \, the feedback is diminished by the "damping" as a percentage.
-So zero HF damping means equal reverb time at all frequencies \, and
-100% damping means almost nothing above the crossover frequency gets
-through.;

-#X text 33 457 stabletime: time period to wait before reporting a note
-(affects "notes" output only). The "pitch" must be present and must
-not vary more than "vibrato" for this entire period to report a note.

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) 19yy <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) 19yy name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

- GNU LESSER GENERAL PUBLIC LICENSE
- Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
- This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
- 0. Additional Definitions.
-
- As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
- "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
- An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
- A "Combined Work" is a work produced by combining or linking an
-Application with the Library. The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
- The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
- The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
- 1. Exception to Section 3 of the GNU GPL.
-
- You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
- 2. Conveying Modified Versions.
-
- If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
- a) under this License, provided that you make a good faith effort to
- ensure that, in the event an Application does not supply the
- function or data, the facility still operates, and performs
- whatever part of its purpose remains meaningful, or
-
- b) under the GNU GPL, with none of the additional permissions of
- this License applicable to that copy.
-
- 3. Object Code Incorporating Material from Library Header Files.
-
- The object code form of an Application may incorporate material from
-a header file that is part of the Library. You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
- a) Give prominent notice with each copy of the object code that the
- Library is used in it and that the Library and its use are
- covered by this License.
-
- b) Accompany the object code with a copy of the GNU GPL and this license
- document.
-
- 4. Combined Works.
-
- You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
- a) Give prominent notice with each copy of the Combined Work that
- the Library is used in it and that the Library and its use are
- covered by this License.
-
- b) Accompany the Combined Work with a copy of the GNU GPL and this license
- document.
-
- c) For a Combined Work that displays copyright notices during
- execution, include the copyright notice for the Library among
- these notices, as well as a reference directing the user to the
- copies of the GNU GPL and this license document.
-
- d) Do one of the following:
-
- 0) Convey the Minimal Corresponding Source under the terms of this
- License, and the Corresponding Application Code in a form
- suitable for, and under terms that permit, the user to
- recombine or relink the Application with a modified version of
- the Linked Version to produce a modified Combined Work, in the
- manner specified by section 6 of the GNU GPL for conveying
- Corresponding Source.
-
- 1) Use a suitable shared library mechanism for linking with the
- Library. A suitable mechanism is one that (a) uses at run time
- a copy of the Library already present on the user's computer
- system, and (b) will operate properly with a modified version
- of the Library that is interface-compatible with the Linked
- Version.
-
- e) Provide Installation Information, but only if you would otherwise
- be required to provide such information under section 6 of the
- GNU GPL, and only to the extent that such information is
- necessary to install and execute a modified version of the
- Combined Work produced by recombining or relinking the
- Application with a modified version of the Linked Version. (If
- you use option 4d0, the Installation Information must accompany
- the Minimal Corresponding Source and Corresponding Application
- Code. If you use option 4d1, you must provide the Installation
- Information in the manner specified by section 6 of the GNU GPL
- for conveying Corresponding Source.)
-
- 5. Combined Libraries.
-
- You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
- a) Accompany the combined library with a copy of the same work based
- on the Library, uncombined with any other library facilities,
- conveyed under the terms of this License.
-
- b) Give prominent notice with the combined library that part of it
- is a work based on the Library, and explaining where to find the
- accompanying uncombined form of the same work.
-
- 6. Revised Versions of the GNU Lesser General Public License.
-
- The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
- Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
- If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-New in Version 0.3
--Full function functionality
-
-------------
-
-The object "expr" is used for expression evaluaion of control data.
-
-Expr~ and fexpr~ are extentions to the expr object to work with vectors.
-The expr~ object is designed to efficiently combine signal and control
-stream processing by vector operations on the basis of the block size of
-the environment.
-
-fexpr~ object provides a flexible mechanism for building FIR and
-IIR filters by evaluating expressions on a sample by sample basis
-and providing access to prior samples of the input and output audio
-streams. When fractional offset is used, fexpr~ uses linear interpolation
-to determine the value of the indexed sample. fexpr~ evaluates the
-expression for every single sample and at every evaluation previous
-samples (limited by the audio vector size) can be accessed. $x is used to
-denote a singnal input whose samples we would like to access. The syntax
-is $x followed by the inlet number and indexed by brackets, for example
-$x1[-1] specifies the previous sample of the first inlet. Therefore,
-if we are to build a simple filter which replaces every sample by
-the average of that sample and its previous one, we would use "fexpr~
-($x1[0]+$x1[-1])/2 ". For ease of when the brackets are omitted, the
-current sample is implied, so we can right the previous filter expression
-as follows: " fexpr~ ($x1+$x1[-1])/2". To build IIR filters $y is used
-to access the previous samples of the output stream.
-
-The three objects expr, expr~, and fexpr~ are implemented in the same object
-so the files expr~.pd_linux and fexpr~.pd_linux are links to expr.pd_linux
-This release has been compiled and tested on Linux 6.0.
-
---------
-
-Here are some syntax information: (refer to help-expr.pd for examples)
-
-Syntyax:
-The syntax is very close to how expression are written in
-C. Variables are specified as follows where the '#' stands
-for the inlet number:
-$i#: integer input variable
-$f#: float input variable
-$s#: symbol input variable
-
-Used for expr~ only:
-$v#: signal (vector) input (vector by vector evaluation)
-
-Used for fexpr~ only:
-$x#[n]: the sample from inlet # indexed by n, where n has to
- satisfy 0 => n >= -vector size,
- ($x# is a shorthand for $x#[0], specifying the current sample)
-
-$y#[n]: the output value indexed by n, where n has to
- satisfy 0 > n >= -vector size,
- $y[n] is a shorthand for $y1[n]
-
-
-I'll appreciate hearing about bugs, comments, suggestions, ...

- * where x is either i(integers), f(floats), and s(strings); and #
- * is a digit that coresponds to the inlet number. The string variables
- * can be used as strings when they are quoted and can also be used as
- * table names when they are followed by "[]".
- *
- * signal vectors have been added to this implementation:
- * $v# denotes a signal vector
- * $x#[index] is the value of a sample at the index of a the signal vector
- * $x# is the shorthand for $x#[0]
- * $y[index] is the value of the sample output at the index of a the

- * the last argument is a pointer to a struct ex_ex for
- * the result. Up do this point, the content of the
- * struct ex_ex that these functions receive are either

- * char ** and not char * since NewHandle of Mac returns

- * these functions is that they figure out the type of their
- * result according to the type of the arguments. In general
- * the ET_SYM is used an ET_INT when we expect a value.
- * It is the users responsibility not to pass strings to the

- * Fiddle is a pitch tracker hardwired to have hop size ("H") equal to
- * half its window size ("N").
- *
- * This version should compile for Max "0.26," JMAX, Pd, or Max/MSP.
- *
- * The "lastanalysis" field holds the shifted FT of the previous H
- * samples. The buffer contains in effect points 1/2, 3/2, ..., (N-1)/2
- * of the DTFT of a real vector of length N, half of whose points are zero,
- * i.e., only the first H points are used. Put another way, we get the
- * the odd-numbered points of the FFT of the H points, zero padded to 4*H in
- * length. The integer points 0, 1, ..., H-1
- * are found by interpolating these others, using the fact that the
- * half-integer points are band-limited (they only have positive frequencies.)
- * To facilitate the interpolation the "lastanalysis" buffer contains
- * FILTSIZE extra points (1/2-FILTSIZE, ..., -1/2) at the beginning and
- * FILTSIZE again at the end ((N+1)/2, ..., FILTSIZE+(N-1)/2). The buffer
- * therefore has N+4*FILTSIZE floating-point numbers in it.
- *
- * after doing this I found out that you can just do a real FFT
- * of the H new points, zero-padded to contain N points, and using a similar
- * but simpler interpolation scheme you can still get 2N points of the DTFT
- * of the N points. Jean Laroche is a big fat hen.

-#X text 231 37 The creation arguments (level \, liveness \, crossover
-frequency \, HF damping) may also be supplied in four inlets as shown.
-The "liveness" (actually the internal feedback percentage) should be
-100 for infinite reverb \, 90 for longish \, and 80 for short. The
-crossover frequency and HF damping work together: at frequencies above
-crossover \, the feedback is diminished by the "damping" as a percentage.
-So zero HF damping means equal reverb time at all frequencies \, and
-100% damping means almost nothing above the crossover frequency gets
-through.;

-#X text 236 56 The creation arguments (level \, liveness \, crossover
-frequency \, HF damping) may also be supplied in four inlets as shown.
-The "liveness" (actually the internal feedback percentage) should be
-100 for infinite reverb \, 90 for longish \, and 80 for short. The
-crossover frequency and HF damping work together: at frequencies above
-crossover \, the feedback is diminished by the "damping" as a percentage.
-So zero HF damping means equal reverb time at all frequencies \, and
-100% damping means almost nothing above the crossover frequency gets
-through.;
