Working on a project and I'd like to add some groovy light effect. Breadboarded a couple sound-to-light circuits and found that using an entire optical compressor sidechain gives a very nice and smooth result. Problem of course is it's a lot of circuit.
Wondering if anyone has suggestions for something simpler with a smooth response.
If you google "Colour Organ" you'll get a few dozen circuits :)
It was a very popular disco effect.
there is a VU meter on THcustoms website (iirc along with the Uboat suboctave pedal). It's based around just one IC and works quite well and has a low part count.
I've built it in SMD a while back: http://www.madbeanpedals.com/forum/index.php?topic=23911.msg233946#msg233946
I used this one (LM386)

That is spectacular! Did you do a build report thread on that?
Cheers man! I built a few to sell but haven't figured out how to do that yet 😂

I used this in my Beast Mode. This layout can be made quite a bit smaller if you take out the second row and you're willing to wire the resistor offboard on an LED and the grounds to wherever.

I'm assuming that's a 386? (or some similar audio amp?)

That's so cool. How do the LED's light up at different times like that? Seems like chaos in a great way.
