Steve and Eric, Thanks for the ideas. Sound Stretch looks quite interesting, but I'm not sure if it handles the file format part of the problem. I certainly need 24-bit capabilities. The page says 'wave' and '16-bit PCM'. The program looks like a good starting point though. (And I'm running Mandrake this evening, so I think it might be easier to build. We'll see...) Sox looks interesting. Quite a lot of capabilities there also. Maybe I need to do something to take advantage of the 'Acidized' feature of the loops also? Acid loops have tempo and root note info in the files. It would be nice to somehow be able to use that to get a better result. I wonder if Swami might have some of the capabilities I'm looking for? Again, thanks for the ideas!
