PinkNoise : WhiteNoise : UGen : AbstractFunction : Object

Pink Noise.
Source: Noise.sc

Description

Generates noise whose spectrum falls off in power by 3 dB per octave, which gives equal power over the span of each octave. This version is band-limited to 8 octaves.

Internally, this UGen calculates its output by means of the Voss-McCartney algorithm. http://www.firstpr.com.au/dsp/pink-noise/allan-2/spectrum2.html

NOTE: The values produced by this UGen were observed to lie with very high probability between approximately -0.65 and +0.81 (before being multiplied by mul). The signal's RMS is approximately -16 dB.
