+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. Except as noted otherwise, all

+
+Note that "expr" is under the GPL, which is more restrictive than Pd's own
+license agreement.
+
+This package should run under linux, NT, or IRIX, except for
+"bilge" which is for NT only.  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)
+bilge (NT only) - play audio CDs through the regular PC sound system
+
+abstractions:
+hilbert~ - Hilbert transform for SSB modulation
+complex-mod~ - ring modulation for complex (real+imaginary) audio signals
+rev1~ - reverberator
+
+These objects are part of the regular Pd distribution as of Pd version
+0.30.  Macintosh versions of fiddle~, bonk~, and paf~ are available
+from http://www.crca.ucsd.edu/~tapel

+Bonk check the attack against a collection of stored templates to try

The quality of the match is the dot product of the two vectors after normalizing them \, i.e. \, the vector whose direction is closest to that of the input wins.;

For example \, you might have stored a number of melodies \, of which some are syncopated \, some chromatic \, some are more than 100 years old \, some are bugle calls \, and some are Christmas carols. You could then ask to find a syncopated bugle call (1 \, 0 \, 0 \, 1 \, 0) and you'll get the thing most closely matching the request.;

+#X text 226 4 FIDDLE - pitch estimator and sinusoidal peak finder;
+#X text 8 70 The Fiddle object estimates the pitch and amplitude of an incoming sound \, both continuously and as a stream of discrete "note" events. Fiddle optionally outputs a list of detected sinusoidal peaks used to make the pitch determination. Fiddle is described theoretically in the 1998 ICMC proceedings \, reprinted on http://man104nfs.ucsd.edu/~mpuckett.;
+#X text 8 170 Fiddle's creation arguments specify an analysis window 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 is 2-1/2 cycles per analysis windows \, or about 108 Hz. (just below MIDI 45.);
