class:: PV_Diffuser
summary:: Random phase shifting.
related:: Classes/FFT, Classes/IFFT, Classes/PV_PhaseShift, Classes/PV_PhaseShift90, Classes/PV_PhaseShift270
categories:: UGens>FFT
Description::
Adds a different constant random phase shift to each bin. When triggered, it selects a new set of random phases.
classmethods::
method::new
argument::buffer
FFT buffer.
argument::trig
A trigger, that selects a new set of random values.
Examples::
code::
(
// trig with MouseY crossing center of screen
{
var in, chain;
in = Mix.ar(SinOsc.ar(200 * (1..10), 0, Array.fill(10, { rrand(0.1, 0.2) }) ));
chain = FFT(LocalBuf(2048), in);
chain = PV_Diffuser(chain, MouseY.kr > 0.5 );
0.5 * IFFT(chain).dup;
}.play
);
(
b = Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01.wav");
// trig with MouseY crossing center of screen
{
var in, chain;
in = PlayBuf.ar(1, b, BufRateScale.kr(b), loop: 1);
chain = FFT(LocalBuf(2048), in);
chain = PV_Diffuser(chain, MouseY.kr > 0.5 );
0.5 * IFFT(chain).dup;
}.play
);
