hey,
I built this circuit and i must say, it works great. I did a couple modifications to it though, i used a 100uF cap instead of the 220uF from the schematics because i found a bit of a delay with the light the sound (no idea if thats what affects the delay but it worked) and i also completely took out the 10K pot from the audio input.
My question is though, i noticed the LED is only sensative to high pitched sounds (claps, singing etc.), I've tried many many songs on it and have come to that conclusion. How would I be able to tune it to be senstive to the bass instead of higher pitches? what part of the circuit affects that aspect. Thanks, any help is appreciated.
