	Perhaps the most readable specs you will find anywhere are the ones I 
have been compiling in the MultimediaWiki. I'm obsessed with the "nuts 
and bolts" operations of codecs, i.e., everything you need to know to 
write a piece of software to interpret a format. These are the basics:

And for decoding low complexity (LC) stereo audio data from Apple 
QuickTime files (most common):

   http://wiki.multimedia.cx/index.php?title=Reconstructing_AAC_CPE

Work in progress, of course, but hopefully it will whet your 
appetite/steel your nerves for what's to come.

	Have fun...
