Audio Crossover light controller circuit

[davelong40]

I'm looking for plans for a low voltage (LED) audio crossover light controller to operate three differently colored LEDs. Does anyone know of such?

This is my first post so please forgive me if I've posted in the wrong place.

It is called a "color organ circuit". You want it to have three frequency bands. Look for the circuits in Google Images where you will find hundreds of them.
