Long Zheng at istartedsomething has compiled a comparison of XP and Vista system sounds. Done up nice in a Quicktime format where the visual displays what the sound is for on the system.
It works (for me at least at 6 a.m.) as music, a call-and-response piece, where Vista is the more demure of the two, the playful little bird responding to the crow. Please listen – tell me what you think!
I hope some audio-meister grabs this and adds OS X system sounds and then mash it into something new. I predict you will be digged, delicioused, redditted, slashed, etc. (Please mention me!)
Robert Fripp (King Crimson founder) recorded (composed?) the Vista sounds. Video of that session here (Windows Media Player format). They are one of my favorite groups, In the Court of the Crimson King (1969) one of my favorite albums.
