WebIn audio engineering, electronics, physics, and many other fields, the color of noise or noise spectrum refers to the power spectrum of a noise signal (a signal produced by a stochastic process). Different colors of noise have significantly different properties. WebWe discuss techniques of modelling the power spectrum of variability in cases where the spectral power is continuous but diverges strongly to low frequencies (so-called `red …
