I posted a link to I believe MPEG is a more efficient compression than say, zipping a .wav file. Anyone have any data on that? |

This means that zipping a .wav file is not worth the effort. MPEG algorithms result in good compression but lossy compression means that you can never restore the file to the original - there will always be some small deterioration in the quality. The latest version is MPEG 2 layer 3 (usually shortened to MP3). This apparently gives compression rates of 10:1 to 14:1 with undectable (to the ear) loss in quality. Note that the URL given by Bill D is layer 2. Do a search for MP3. For copyright reasons MP3 encoders are hard to find (broken links etc.), but decoders and players can be found. I haven't had time to try any of this but I believe MP3 is a very promising way of exchanging audio.
