Hehe, you're right. The heat must be getting to me.
Another crazy idea: What about random sampling? Taking only a few 
samples per audio sample such that the audio sampling rate is 
sufficiently high and let the result converge to something meaningful 
along the way. Probably even worse than raytracing for some reason. I'd 
better put of any serious thought until this room cools down. ;-)
