i checked back through the post in this forum to see if I could find a similar problem. I didn't find one. I uploaded a test noodle to check out the new studio setup. I can play my master stereo wav. it plays the right speed . I checked my mp3 coversion and it's fine.

  When I uploaded the mp3 to bandamp the speed slowed down. it sounds like a variable speed tape deck that's been slowed down some. Have you had any problems with this before? any suggestions?

This problem occurs when you set the conversion properties to 48 kHz instead of 44.1. The bandamp player always plays at 44.1, it doesn't read the actual mp3 properties, so that's the problem....

I was wondering if that was the problem,that was the only thing that I had changed that I know of. I will convert back to 44.1.
