Pink noise generator


pink~ generates pink noise, as distinguished from white noise (which the MSP object noise~ generates). White noise has constant spectral power per hertz of bandwidth, while pink noise has constant power per octave. Subjectively, pink noise sounds less hissy than white noise.



Information for box attributes common to all objects


signal: The pink~ object generates a signal consisting of random value in the range -1.0 to 1.0, with an even distribution of power per octave of frequency. Noise with this power distribution is known as "pink noise". "White noise", as generated by the object noise~, has an even distribution of power over all frequencies. Perceptually, white noise sounds bright and harsh, and pink noise sounds more even and "natural".


pink~ generates random numbers such that the frequency content is equal power per octave
