Lots on Audio Coding...
A Fallacy in the Model + Coder paradigm
An Adaptive Quantum Coder
Created 1-13-98, Modified 1-18-98.
The 2nd law of thermodynamics
implies you cannot compress all possible inputs, and other info-theoretic results. (!) Now with Quantum Info analogue. Created 1-10-98, Modified 1-28-98.

Notes on the new MACM-96 Arithcoder
Shannon's derivation of Entropy
No Magic Compressors
also contains a proof that the Entropy is the minimum attainable limit by any coder, and something of a derivation of the Kraft inequality.
