Need help building an rgb led music sync.?
I see a lot of step by steps showing how to build a simple vu meter but I am looking to do something a little different.
I am currently building a new desk and along the back side of the desk I want to install a row of rgb led's. I would like to set them up so that the led's change color from green to red in increments based on the volume level associated to a certian frequency. so the far left of the desk responds to low frequency and the far right would be high.
I think this would be pretty cool effect but need some help connecting the dots. I am hoping there may be some adruino programing availibe to do the signal proccesing and then for each signal I would just need individual volume meters?
the only other thing missing is where to incorporate the rgb settings.

Do any of the Instructables under "related" do what you want? If not, what don't they do?
If you want more references, websearch "LED color organ".

it is amazing how much the right search term helps. the color organ is almost exactly what I was looking for. I just need to try to find a design that incorporates rgb led's, instead of single color. using some op amps I should be able to to seperate the l and r audio channels by low, mid and high frequencies.
