I'd like to see a video about the windows media audio codec and how it works in as much detail as is allowed.

I've always been using mp3 files until now. Back with the older windows media codec, the one that shipped with the inital release of XP sounded awful at 64kbps. But the codec that ships with windows media 11 seems vastly improved.

I'm curious as to how this was acheived as i thought you couldn't mathematically  do better than splitting the audio signal into 4 bands and then performing a DCT (discrete cosine transform) on the 4 bands and storing that data, which is how mp3 works.
