This is the old version of the sound file used when SCP-096 is enraged.
The sound file is used in the game on versions 0.6.0 - 0.6.2. This was changed in version 0.6.3 - 0.7.4.
Addendum: It sounds like a giant vacuum swallowing up an ocean of spaghetti. It may sound completely stupid, but that's just what it sounds like to me.
EDIT: The picture was slightly off-centered. Damn you, OCD.
