This is not a new concept in Flash, but as far as I could tell, there weren’t many solutions for this in Flex. Here’s my stab at doing an equalizer. Watch out for your ears, the volume is set to 100% by default.

I do have one small problem with it, and I’m working to figure it out… for reasons unknown to me the SoundMixer.computeSpectrum function will return a null array sometimes. I have absolutely no clue why, and I’m open to any suggestions as to why. It only errors in the first 5 seconds.
Update: Figured it out. The problem was that I was relying on EnterFrame to call the render method on the equalizer. Unfortunately, EnterFrame could potentially be dispatched before the sound file was loaded from the server, therefore computeSpectrum wouldn’t have any sound data to work with. This would cause computeSpectrum to return me a null array.
