LFNoise2 | SuperCollider 3.13.1 Help

Description

Generates quadratically interpolated random values at a rate given by the nearest integer division of the sample rate by the freq argument.

NOTE: quadratic interpolation means that the noise values can occasionally extend beyond the normal range of +-1, if the freq varies in certain ways. If this is undesirable then you might like to clip2 the values, or use a linearly-interpolating unit instead.

Class Methods

LFNoise2.ar(freq: 500.0, mul: 1.0, add: 0.0)

From superclass: LFNoise0

LFNoise2.kr(freq: 500.0, mul: 1.0, add: 0.0)

From superclass: LFNoise0

Arguments:

freq	Approximate rate at which to generate random values.
mul	Output will be multiplied by this value.
add	This value will be added to the output.
