I've got this idea and I'm trying to determine if its possible and the best method to do it...
Basically what I want to do is feed an audio signal into my circuit which is low passed at ~150Hz by my subwoofer amp. The circuit will then process the audio and flash an LED (or possibly a strobe light) with a freq. slightly slower than the audio (differing by 1-2Hz). If it works properly, it should look like the subs are just slowly moving in and out (at the 1-2hz difference).
I think I might need to add another LPF in there to cut the freq down to 80Hz or lower since there isnt alot of excursion at the higher freqencies.
It might be easier to do this with a pic...if its even possible.
