For decades I’ve been reading about 1/f noise and have been curious what it sounds like. I’ve always been meaning to write a little program to generate some and then play it on a speaker, but I’ve never put the effort into figuring out exactly how to do it. But now with Google . . . there must be some 1/f noise out there already, right?
A search on “1/f noise” yielded this little snippet of 1/f noise simulated by Paul Bourke from a deterministic algorithm. It sounded pretty cool, like what I’d imagine computer music to sound like.
I did a little more searching on the web; it was easy to find algorithms and code for generating 1/f (“pink”) noise but surprisingly difficult to find actual sounds. I finally found this 15-second sinppet, which sounded like ocean waves, not like computer music at all! (You can compare to the sample of white noise, which indeed sounds like irritating static.)
I also found this online 1/f noise generator from a physics class at Berkeley. It works, also shows the amplitude series and spectrum. Also sounds like ocean waves. I’m disappointed–I liked the computer music. What’s the deal?
