Sound Sensative LED

I wanted to make an LED board that I could wear on my shirt or hat that can sense bass sounds (like in and around 80Hz). I play House music, and it would be an awesome visual aspect, and wondered if someone had an instructable on it. Thanks

You need to look up "color organ"; a rather old circuit that usually has three channels (trebel, midrange, bass) that flash in some sort of relationship to sound intensity in each range. You'd only need the bass part, I guess, though it might
be tough to figure out which parts of the circuit need to be left behind.

This circuit looks very close to what you're asking for, and not too unlike an instructable, either.
