class:: PV_RandComb
summary:: Pass random bins.
related:: Classes/PV_RandWipe
categories:: UGens>FFT
Description::
Randomly clear bins.
classmethods::
method::new
argument::buffer
FFT buffer.
argument::wipe
Clears bins from input in a random order as wipe goes from 0 to
1.
argument::trig
A trigger, that selects a new random ordering.
Examples::
code::
s.boot;
(
b = Buffer.alloc(s,2048,1);
c = Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01.wav");
)
(
SynthDef("help-randcomb", { arg out=0, bufnum=0;
var in, chain;
in = {WhiteNoise.ar(0.8)}.dup;
chain = FFT(bufnum, in);
chain = PV_RandComb(chain, 0.95, Impulse.kr(0.4));
Out.ar(out, IFFT(chain).dup);
}).play(s,[\out, 0, \bufnum, b.bufnum]);
)
(
//trig with MouseY
SynthDef("help-randcomb2", { arg out=0, bufnum=0, soundBufnum=2;
var in, chain;
in = PlayBuf.ar(1, soundBufnum, BufRateScale.kr(soundBufnum), loop: 1);
chain = FFT(bufnum, in);
chain = PV_RandComb(chain, MouseY.kr, Impulse.kr(0.4));
Out.ar(out, IFFT(chain).dup);
}).play(s,[\out, 0, \bufnum, b.bufnum, \soundBufnum, c.bufnum]);
