SHORTEN: SIMPLE LOSSLESS AND NEAR-LOSSLESS WAVEFORM COMPRESSION

Tony Robinson

December 1994

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.

If you have difficulty viewing files that end '.gz', which are gzip compressed, then you may be able to find tools to uncompress them at the gzip web site.

If you have difficulty viewing files that are in PostScript, (ending '.ps' or '.ps.gz'), then you may be able to find tools to view them at the gsview web site.

We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
