Are you talking here about an AIFF exported by Audacity?
Save as AIFF in what application? If you have a problem with Amadeus you’ll need to contact them.
Peak is no longer made so you’re stuck with whatever it does.
What is a “threepeat”?
So is the issue now not with AIFF files playing on iPod, but with AIFF files exported from Audacity using Export Multiple?
If you export a single AIFF from a whole track, with all metadata fields completed, do Amadeus and Peak have the same problem?
