FFTease - A set of Live Spectral Processors
Originally written by Eric Lyon and Christopher Penrose for the Max/MSP platform
Copyright (c)Thomas Grill (xovo@gmx.net)
For information on usage and redistribution, and for a DISCLAIMER OF ALL
WARRANTIES, see the file, "license.txt," in this distribution.
----------------------------------------------------------------------------
The package should at least compile (and is tested) with the following compilers:
pd - Windows:
-------------
OK o Microsoft Visual C++ 6: edit "config-pd-msvc.txt" & run "build-pd-msvc.bat"
o Cygwin: edit "config-pd-cygwin.txt" & run "sh build-pd-cygwin.sh"
additional settings (e.g. target processor, compiler flags) can be made in makefile.pd-cygwin
pd - linux:
-----------
o GCC: edit "config-pd-linux.txt" & run "sh build-pd-linux.sh"
additional settings (e.g. target processor, compiler flags) can be made in makefile.pd-linux
pd - MacOSX:
-----------
OK o GCC: edit "config-pd-darwin.txt" & run "sh build-pd-darwin.sh"
additional settings (e.g. target processor, compiler flags) can be made in makefile.pd-darwin
Max/MSP - MacOS 9:
------------------
OK o Metrowerks CodeWarrior V6: edit & use the "fftease.cw" project file
You must have the following "Source Trees" defined:
"flext" - Pointing to the flext main directory
"Cycling74" - Pointing to the Cycling 74 SDK
Max/MSP - MacOSX:
------------------
OK o Metrowerks CodeWarrior V6: edit & use the "fftease.cw" project file
You must have the following "Source Trees" defined:
"OS X Volume" - Pointing to your OSX boot drive
"flext" - Pointing to the flext main directory
"Cycling74 OSX" - Pointing to the Cycling 74 SDK for xmax
"MP SDK" - Pointing to the Multiprocessing SDK (for threading support)
----------------------------------------------------------------------------
PORTING NOTES:
The example audio files schubert.aiff and nixon.aiff have been taken from the original FFTease package for Max/MSP.
- pv-lib:
- gcc (OSX) complains about _cfft being defined by pv-lib and pd.... any problems with that?
- burrow:
- max_bin calculation: fundamental frequency seems to be wrong
- cross:
- STRANGE: spectral amplitude in channel1 is undefined if gainer <= threshie
-> value of previous frame is used then
- (jmax) BUG: a2 for i == N2 is calculated from buffer1
- what about the class members for "correction"?! (superfluous)
- dentist:
- tooth count ("teeth") is preserved and checked on every reshuffle
- use different knee correction
- disarray:
- different frequency correction employed
- max_bin calculation: fundamental frequency seems to be wrong
- check whether freq oder number of bins should be selectable -> frequency!
- ether:
- possibility to change qual?
- scrape:
- maxamp is computed (from spectral amplitudes) before these are set!! (function frowned) -> corrected
- shapee:
- danger of div by 0... corrected
- swinger:
- (jmax) phase is calculated from signal1 (instead of correct signal 2)!!
