Class thl::dsp::utils::BrownianNoise

class BrownianNoise

Brownian motion (random walk) noise generator with one-pole smoothing.

Integrates a velocity state that receives random impulses at rate Hz. A spring-like restoring force and velocity damping keep the output bounded in approximately [-1, 1] without hard clipping.

Call prepare() before use.

Parameters: rate – impulse rate in Hz (controls how fast the value wanders) momentum – spring/damping strength [0, 1] (higher = stronger mean reversion)
