It produces .SHN files that are roughly 1/2 the size of the .WAV, but... you can't play a SHN file (yet). You have to decompress it to a WAV and listen to it that way. So, it's good for up/down-loading music and for archiving music. You can whip up a little script to play CDs full of SHN files. I did. It just decompresses the SHN off of a CD and pipes the output directly to "play" so that I can keep twice the music on a single CD. I don't remember the Shorten website name exactly, but there is a link to it off of my website. http://www.hydrofunk.org/music peace, --Paco On Sat, 17 Jun 2000, Sergey wrote: > Hi! > Have someone heard of "Multimedia compression"? > I mean, a special Zip (WINZIP :( ) which compresses PCM WAVes without > losses.
