White, pink, red, blue and purple noise are available, each of the noise colors has two individual outputs.
- white: flat spectral power density. This is the raw sound of electrons breaking through a reverse biased semiconductor junction.
- pink: slightly filtered -3db/oct spectral power density. Also known as 1/f noise, pink noise exhibits equal power across all proportional frequency bands.
- red: 1-pole lowpass noise with -6db/oct spectral power density. Tthis spectrum of noise emulates Brownian Motion, also known as the random or drunken walk.
- grey: spectral density is based on an A-weighting (sound pressure) curve which exhibits the effect of the majority of the audible spectrum being equally loud.
- blue: +3db/oct spectral power density. the inverse of pink noise - where the power density is directly proportional to the frequency.
- purple: +6db/oct spectral power density. purple noise has a power density directly proportional to the square of the frequency
- quanta: binary quantized noise which sounds crackly, yet dense.
noise outputs: white, pink, red, grey, blue, purrple, quantized
