|
|
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.

@section{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.
