Massive Equalizer with Bluetooth Input - Feasability

I have been playing around with a small Arduino and some LEDs, and I had an idea for a massive equalizer that will get a signal through a Bluetooth receiver and also play the music through a hardwired stereo. I know I have a long way to go in order to finish this, but I want to make sure I am starting off on the right foot, and I wanted to check and see if this project is even possible.

Do you mean equaliser or spectrum analyser?

I don't see why the audio Equalizer is necessary. If you want to patch music from a bluetooth to a stereo you probably need something like this:

I should have been clear on that. I am looking to make a large LED spectrum equalizer. I basically want to make a very cool light display for parties and general awesomeness. I wanted to do this through Bluetooth so that I can play music from any phone into an audio system. I was thinking that I could have the audio signal pass through the board and both analyze and send it through to a hardwired dedicated audio system built onto their own cabinet. I want to add a few different components just for practice and fun. I though tackling Bluetooth and LED controls would be a good start.

Then you probzbly want to mix rhe WS2803 with thr grapjic equalizer.
