Multimedia compression

[Sergey]

Hi!
 Have someone heard of "Multimedia compression"?
 I mean, a special Zip (WINZIP :( ) which compresses PCM WAVes without
 losses. (Special optimized algorythms are used)
 Is there something like that for Linux?
 
 As I know, it will save 30-40% of disk space if you store plain PCMs -
whiel a ususal bzip or zip saves just about 5%.
 
 Please do not write of mpeg or any other "destructive" compression.
