In MPEG Layer III coding the compression gain is mainly achieved through the unequal distribution of energy in the different frequency bands, the use of the psychoacoustic model, and Huffman coding.

The Layer II coder provides a higher compression rate by making some relatively minor modifications to the Layer I coding scheme. These modifications include how the samples are grouped together, the ...

Information theory provides a unifying framework for both model selection and data compression by quantifying the trade-off between model complexity and the fidelity with which a model represents data ...
