I'm happy both with the ability of iTunes to burn CDs and with the ease of transferring even cassette tape files to the iTunes' library. But in the case of the tapes I'd like to be able to reduce the noise in the treble (not just tape hiss, either) as well as boost bass frequencies.
1. What's a program that allows some equalization and in real-time (so you don't have to keep playing it to see if it worked)?
2. Is the equalization best applied before, during, or after the music has been recorded and saved to hard disk as an AIFF file?
