From 65a1b98552d7c6a93aedfb7c9b5d83f9038227cb Mon Sep 17 00:00:00 2001 From: Miller Puckette Date: Sat, 31 Dec 2005 00:59:49 +0000 Subject: Added about 64 files that I hadn't realized weren't in the CVS repository. Threw in pd/portaudio/pa_win_wdmks for good measure, although I haven't tried compiling that in yet (no windoze machine handy today). svn path=/trunk/; revision=4316 --- pd/extra/fiddle~/fiddle~-help.pd | 142 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 142 insertions(+) create mode 100644 pd/extra/fiddle~/fiddle~-help.pd (limited to 'pd/extra/fiddle~/fiddle~-help.pd') diff --git a/pd/extra/fiddle~/fiddle~-help.pd b/pd/extra/fiddle~/fiddle~-help.pd new file mode 100644 index 00000000..f396725a --- /dev/null +++ b/pd/extra/fiddle~/fiddle~-help.pd @@ -0,0 +1,142 @@ +#N canvas 93 26 980 745 10; +#X obj 262 522 phasor~; +#X obj 531 616 unpack; +#X floatatom 531 666 0 0 0 0 - - -; +#X msg 437 449 print; +#X obj 262 500 sig~; +#X floatatom 262 478 0 0 0 0 - - -; +#X obj 262 456 mtof; +#X floatatom 262 434 0 0 0 0 - - -; +#X floatatom 545 643 0 0 0 0 - - -; +#X obj 531 576 route 1 2 3 4; +#X obj 614 616 unpack; +#X floatatom 614 666 0 0 0 0 - - -; +#X floatatom 628 643 0 0 0 0 - - -; +#X obj 698 616 unpack; +#X floatatom 698 666 0 0 0 0 - - -; +#X floatatom 712 643 0 0 0 0 - - -; +#X obj 389 616 unpack; +#X floatatom 389 666 0 0 0 0 - - -; +#X floatatom 403 643 0 0 0 0 - - -; +#X obj 334 545 *~; +#X obj 322 394 loadbang; +#X obj 353 522 sig~; +#X floatatom 353 500 0 0 0 0 - - -; +#X msg 322 478 1; +#X msg 353 478 0; +#X floatatom 466 666 0 0 0 0 - - -; +#X obj 281 666 print attack; +#X obj 190 666 print pitch; +#X msg 555 45 \; pd dsp 1; +#X text 460 39 click here; +#X text 460 61 to start DSP; +#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).
