Color of Noise & Test Tones

Noise colors are the names of certain types of stationary noise signals, defined by different colors, based on the analogy between the spectrum of a signal of an arbitrary nature and the spectra of various colors of visible light. This abstraction is widely used in branches of technology dealing with noise (acoustics, electronics, physics, etc.).

In this section, you can listen and download various types of noise for free, such as white noise, pink, Brownian (red), blue noise and others. Also included are test tones recorded at various frequencies.

All audio recordings in this section are free to use under a Creative Commons license.
