public class PinkNoise
extends UnitOscillator

Noise_Pink Generate Pink Noise using Gardner method. Optimization suggested by James McCartney uses a tree to select which random value to replace.

Tree is generated by counting trailing zeros in an increasing index. When the index is zero, no random number is selected. Author: Phil Burk (C) 1996 SoftSynth.com, All Rights Reserved.
