PitchShift : UGen : AbstractFunction : Object

Time domain pitch shifter.

Description

A time domain granular pitch shifter. Grains have a triangular amplitude envelope and an overlap of 4:1, and use linear interpolation of the buffer.

Class Methods

PitchShift.ar(in: 0.0, windowSize: 0.2, pitchRatio: 1.0, pitchDispersion: 0.0, timeDispersion: 0.0, mul: 1.0, add: 0.0)

Arguments:

in

The input signal.

windowSize

The size of the grain window in seconds. This value cannot be modulated. The minimum value is 3 sample periods. If you supply a smaller value, it will be rounded up to the minimum.

pitchRatio

The ratio of the pitch shift. Must be from 0 to 4.

pitchDispersion

The maximum random deviation of the pitch from the

pitchRatio .

timeDispersion

A random offset from zero to timeDispersion seconds is added to the delay of each grain. Use of some dispersion can alleviate a hard comb filter effect due to uniform grain placement. It can also be an effect in itself. timeDispersion can be no larger than windowSize.

mul

Output will be multiplied by this value.

add

This value will be added to the output.
