Abstract:
This report describes a program that performs compression of waveform
files such as audio data. A simple predictive model of the waveform is
used followed by Huffman coding of the prediction residuals. This is
both fast and near optimal for many commonly occuring waveform signals.
This framework is then extended to lossy coding under the conditions of
maximising the segmental signal to noise ratio on a per frame basis and
coding to a fixed acceptable signal to noise ratio.
