I'm working on a show that's a couple of years old and I need to stop putting it off. I gradually lowered the recording volume about 12db over a space of 1 minute. I'd like to reverse this. Should I chop up that 1 minute section into 24 2.5 second chunks and add .5db increases incrementally? I don't think my software has a volume envelope function, and I'm under the impression that Audacity (1.3.14-beta for the Mac) doesn't do well exporting 24-bit files. Any suggestions?
