Well, depends on what you mean by uncompressed. They may not have been packed using any sort of general data compression algorithm, but they are fairly random binary data and will not compress much at all. Try gzipping a .wav file; I get about a 3% benefit. bzip2 will not be much better. FLAC (flac.sf.net) is a compression system designed for .wav files; it'll give a bout a 40% saving, losslessly. -rob
