Sorry for repost, but apparently, this post got trashed in my Blog SQL database. Eff me silly, computers suck. Apparently the post showed up long enough for MKB to comment on it, but then went to the great bit bucket in the sky.
The quaintly named Paul Stretch is a program that does extreme time stretching of digital audio. It’s free and open source, so anyone can try it.

Anyhow it turns any audio into pleasant ambient textures. Exampla gratia:
