Audio Analyzer Circuit/Code

post #1 of 4
Thread Starter 
Not sure if this is the right place to put it, but I thought i'd share my audio analyzer circuit! I used Java (processing.org) to code the PC end of it, which uses Fourier transforms to split up the song into multiple sine waves, checking each of their amplitudes at any given point, then communicates to my arduino, which receives, sorts, and uses the given data (With C++) to light up the LEDs!

Also, if you wish to escape my monotonous drone for the first half, heres a video with just a demo:

Thanks guys! I think (when I have some time) I'll get a second 8x8 matrix and solder them to perfboard, may look a little nicer.
