Audio Visualization Template

About
This is an Audio Visualizer Template I made to start making an entry for #Actionscript-as-Art audio visualizer contest [link] [link] [link]

It features "load from drive", "rewinding" and both sound wave and spectrum visualization together.

Aims
But I am actually pursuing more with this then just a starting point for me. Here are my self serving plans with it:
1) To be a starting point for anyone who does not know from where to start (I do wish to see as many work as possible )
2) To enforce adding "load music from hard drive" functionality on other works (I would like to pick my own music to see how it visualizes )
3) To enforce "rewinding" functionality (boy I miss it sometimes with those visualizers , its hard to make to not get in a way of visualization visually though)

P.S Also visualization part here is SLOW. I was thinking on optimizing it but then I understood that this is a good motivation to scrap it and make your own. In the end what I want to share here is not visualization but basic backbone of features for it.

It's AS3 class that theoretically does not depend on Flash IDE/Flex or anything. I used it with empty FLA file that is included too and I am not sure if it will work out of the box with Flex.
