SuperCollider CLASSES

PV_Diffuser

Random phase shifting.

Description

Adds a different constant random phase shift to each bin. When triggered, it selects a new set of random phases.

Class Methods

*new (buffer, trig: 0)

Arguments:

buffer

FFT buffer.

trig

A trigger, that selects a new set of random values.

(
// 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
);

(

// trig with MouseY crossing center of screen
{

    in = PlayBuf.ar(1, b, BufRateScale.kr(b), loop: 1);

    chain = PV_Diffuser(chain, MouseY.kr > 0.5 );
    0.5 * IFFT(chain).dup;
