An early sound toy, created by Andy Wilson of LShift, SoundRaider scanned your PC hard drive for audio files and mixed them together into 'ambient industrial noise'.
SoundRaider plunders its host and plays up to 10 sounds at a time, which have been stretched, compressed, and looped. The result, says Wilson, "is sometimes a bit like listening to your machine cursing, singing, and muttering to itself."
Wilson compares the program's creations to "isolationist ambient" music, and says that "many people - of strong disposition - like to leave it running on the desktop while they work." http://www.wired.com
