SpaceAttack 2812.wav

This was derived from a field recording of a vacuum on carpet. The tone fading in and out is the vacuum mixed with traffic, ocean, seagulls, and arena audience cheering. All sounds have been time stretched or compressed to varying levels. Reverb, panning and stereo widening was applied to give the recording depth.
Now put on the headphones, turn out the lights and get freaked out!
