Hi, just to add that Audacity has a bass and treble effect which works the same way as bass and treble controls on an amplifier. It also has an equalization effect, which includes some preset curves.
David. original message: Audacity does do the speed thing, I'm not sure about the tape thing. SF does the speed change but in your case it's unfortionate because it's SF Pro. To unsubscribe from this list, send a blank email to: pc-audio-unsubscr...@pc-audio.org
