Wikipedia has an article with some other information on pink noise (a more common name), including a random generator: https://en.wikipedia.org/wiki/Pink_noise https://en.wikipedia.org/wiki/Pink_noise. Some music generation algorithms use pink noise, as it (supposedly) strikes a better balance between randomness and predictability.
- rcxdude 2mo agoPink noise is also perceptually flat noise, because it contains the same energy in each octave (or decade). 'truly' white noise (equal energy for equal bandwidth) tends to sound quite tinny/hissy in comparison.
- kadoban 2mo agoI went through a phase of using ~whitenoise while working to block out distractions. Actual white noise indeed sounds really bad and grating. The best for me was a mix of pink and brown noise, pink for an ~equal baseline and brown to make it sound a little more mellow. I suspect most/all generators meant to block out noise do something similar. It really sounds pretty bad without that, especially for anything more than a few seconds.
- rcxdude 2mo agoYeah. pink noise is often confused with white noise in audio because it looks flat on a lot of equaliser displayers (because they show energy per octave instead of energy per Hz).
