MPEG Audio is a family of perceptual codecs. It makes heavy use of
characteristics of human hearing. Apart from knowledge about data
compression, understanding what happens requires knowledge of audio and
psycho-acoustics as well.
If you want to implement something that complies to the standard, you
absolutely need the standard (ISO/IEC 11172-3 , inquire at www.iso.ch). The
standard describes exactly how a decoder must behave, and it gives an
example what an encoder can do.
Layer III is quite complex to understand. Consider layers I and II first.

I am during a project about Data Compression and my project group and I
have thought of focusing on Mpeg and more specific, Audio Layer 3. As we
have little or no knowledge of data compression, we have searched the
internet and read some books. And here comes our problem:
We can't seem to find any material on Mpeg layer 3 of a technical and
tutorial-based nature. All the material we have found is eihter very
"populistic" in its description of the coding or it is completely out of
our league, technically.
If anyone has any information on Mpeg layer 3 or know where to find it,
please mail me.
