Essentially I am looking for what some call a "color Organ". I want to take an audio signal, devide it into three separate signals, Low/Mid/High. Then I want to drive sets of LED's, Red,Yellow, Green. I am looking for each band (Low/Mid/High) to flash based on the beat of the Base, Midrange, and Trebble. I plan to put the LED's
in a pair of goggles.
Do you have any ideas or suggestions on how I can accomplish this?
Thanks

There is a project on another website that uses an obsolete quad opamp and some hard to find Japanese LED driver ICs.
Make a new topic in the forum and maybe somebody knows a new circuit or we can update the one I saw.

Here is a link to a circuit that does not split the audio into three freq ranges but is said to drive the LED's to music.

I suspect that I would need a gain controll for each of the three freq bands.
