Detailed Description

Random impulse train processed by a resonant filter.

Author

Ported by Ben Sergentanis

Date

Jan 2021 Noise processed by a sample and hold running at a target frequency.

Ported from pichenettes/eurorack/plaits/dsp/noise/particle.h
to an independent module.
Original code written by Emilie Gillet in 2016.
