- Being active in the digital music/mixing field, I would STRONGLY advise
- that ALL PROGRAMMERS should NOT implement ANY type of audio compression
- for professional applications. (ala MAC Alchemy, Sound Tools, DECK, etc).
-
- Compression ratios would make the software worthless. Perhaps for little
- toy editors and such, (strict multimedia, etc.)
