Here is a fractal sound I through together in Goldwave just fooling around with patterns. The original sound is me knocking 5 times on the metal shelving that serves to hold my computer tower and printer and other things. Recorded with a 12-year-old $10 radioshack mic at 44.1 kbps. I then noise reduced it in Goldwave, looped it several times, so there's silence between each loop of knocks, and added a flanging effect I build myself by applying slightly different values in the left and right channels, setting feedback to 100%, input volume to 0, so that the sound rocks back and forth from left to right in a slowly evolving cycle. Then I slowed the playback rate to 8kbps, opened a new file at 44.1 and pasted the slowed down sound in. I then changed the original file to 16kbps and mixed it with my new file. I kept doing this, increasing the playback rate at 8 kbps intervals until I reached 192 kbps. So all of these knocking loops playing at different speeds create an audio spiral. At the end of each loop of the slowest, 8kbps file, the silences in all the other files converge to create one break of silence that lasts as long as the shortest silence, which, in the beginning, belongs to the 192kbps track. After about 53 seconds, the shortest mixed file ends, and they begin dropping off rapidly, but each one taking an ever longer time to drop out, (following the formula Y [in seconds] = 10176/x where x runs from 192 to 8 in intervals of 8), until the 16kbps file drops out around the 10-minute mark, and for the last half of the sound, you just hear the 8kbps file.

This is a very interesting sound experiment.
