Thoughts on an Audio Control of RGB LEDs

Doug, from what I read the LM324 has a 5V buss from the the way it is connected, so I figured that I would just start off with that.... primarily because I was unaware of the optional 1.1V reference. I will have to do some looking into that. I was definitely looking at tracking the peeks to adjust my scaling to get the best effect, as well as eventually adding some additional controls to modify the reaction from an external control (bluetooth via andriod, but that is a ways down the road).

Here is the updated schematic. I have to do some more figuring and testing to get the filter components correct unless someone knows a short cut 8) !! I realized this evening that the original was missing a few components, so the original would not of brought the audio signals up. Which led me to discover one potential problem with doing this way. As Doug mentioned I am probably going to get some loss filtering the signals. If I amplify after the filtering it would be less likely that the loss would be noticed (not that it would be noticed anyways, just a thought). Basically this will always be fed from a headphone jack either from something like an MP3 player or cell phone.

If you happen to see anything that I missed please let me know.
