Using aurora it should be possible to support mp3 and aac : https://github.com/audiocogs

FYI, I just added a few methods that should make this use case much easier for you to implement.

First, I added a more robust version of your BufferSource, and some methods on AV.Asset and AV.Player to easily create instances of those classes fromBuffer. The buffer source can also accept buffer lists if you have a sequence of buffers to decode.

Second, I added a decodeToBuffer method to AV.Asset which allows easily decoding an entire file into a single Float32Array. You'll still need to deinterleave unfortunately, but it should make this much easier. As a subscript to that, the data events and that new method now do the proper conversions so that the data is always returned in floating point format rather than the raw data from the decoder (this was previously done in the player only).

I've updated the documentation as well, both for these new methods and some others added earlier. Just thought I'd let you know, since you have been asking questions and I'm excited to see this project come to fruition! :)

@devongovett amazing!!! Thanks a lot for this :) it will help me a lot indeed! I'll refactor to use those new features immediately.
