You've probably heard the sound of white noise. It's what we perceive as a hiss, and has a flat spectral content across all frequencies. But many other colors of noise exist, each with a different spectral "slope". Some emphasize lower frequencies, while others have a U-shape spectral weighting.

Common noise colors include pink, red, blue and violet, each with different properties and applications.
  • Pink noise, for example, better represents natural phenomena like rain and has been shown to aid sleep and memory
  • Blue noise is used in audio dithering to mask the effect of quantization
This application generates 1D pink, red, blue and violet noise, and produces periodograms for each. Each noise sample is sonified so you can hear what it sounds like.

Additionally, the sound can also be exported to a wave file for use in another tool (Maple will export high precision 32-bit and 64-bit wave files).
