  • Source of random values
  • Drum synthesis (particularly snares)
  • Filtered noise (wind and waterfalls)


This unit outputs pink noise at full-scale. Pink noise differs from white noise in that its power is equally distributed over octaves whereas white noise is equally distributed over frequency. As a result, the sound of pink noise is less overwhelmed by high frequency and tends to rumble where white noise hisses. Pink noise is more often encountered in nature than white noise. The pink noise here is generated using the Voss-McCartney algorithm.
