Really nice article and demos, very informative.

Maybe unsurprisingly, noise is a really important aspect of audio and music as well. A lot of synthesizers have a parameter for adding white or pink noise to sounds. What's interesting is in a lot of music, my ears would never pick out the noise without actively listening very closely, but if you take the noise away the music sounds way more plain and empty in a very subtle way.

FWIW, colored (white/pink/brown) audio noise is conceptually quite different from the kind of noise in this article. Audio noise is intentionally broad-spectrum and usually includes very high frequencies. The interpolated noise such as Perlin noise used for textures is intentionally just a single frequency, and it’s designed specifically to avoid the kind of white noise you get when you call Math.random().
