request: brownian motion in harmonic/other potential

[glocke01]

Hi. Fellow physics+audio nerd.

I'd love to see a smooth-random LFO module based on simple Brownian motion. Basically, add a random nudge at regular (or exponentially distributed intervals) with, say, normal magnitude and uniformly distributed angle. Then just simulated orbit around a harmonic potential. Parameters would be potential strength and nudge strength. Additional possibilities include damping terms, nudge-on-trigger, inputs that insert force, bias in nudge angle (prefer tangential motion), non-trivial potentials, e.g. bistable.

Alternatively, simple brownian motion with no potential (with/without damping) on periodic boundary conditions would also be interesting. (or periodic boundary conditions and periodic potential, etc. etc..)

Best, George
