I’ve heard music coming from interactions between an air filter and a box fan. The sound plagues me when I try to sleep without aid of booze. Sometimes it sounds like dixieland jazz, other times it’s Steve Reich.
I have not captured the music from those two devices but I seem to have unwittingly snagged it from another place I hear it: The shower. The way the water circles the drain in particular seems to be a rich source for this kind of drone music. The music was not in the original .WAV file, though. It came up after a bit of noise cancellation filtering. See if you hear it between the sounds of my voice. I hear voices and raga type continuousness.
