PV_Diffuser : PV_ChainUGen : WidthFirstUGen : UGen : AbstractFunction : Object

Random phase shifting.
Source: FFT.sc

Description

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

Class Methods

PV_Diffuser.new(buffer, trig: 0)

Arguments:

buffer

FFT buffer.

trig

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