I've noticed it on a few tapes that it is playing too fast/slow (cant remember which). So today I decided to pay more attention. Its a 44k tape and that is what I have my M-Audio set at as well as Audacity.
The opening band set on the tape had the issue I highlighted earlier today. After I saved that file, I'm working on the main band right now, and it looks to be the other way around and the tape is now running slow! Seems really odd.....
I haven't tried other tapes yet.....
