Where can I get a technical description, and the source code for the
algorithms that do the compression and decompression?

What compression ratios can be achieved?

Is stereo treated as two mono chanels, or can we do better by encoding
sum and difference?

Thanks.

You will find pointers to many useful sites at:

http://www.mpeg.org/~tristan/MPEG/audio.html

There is also a section on MP3 elsewhere on the mpeg.org site.
