audio sync drift - fcp to adobe and back

I've done this many time before but on this one project, I'm having a problem.

I have edited FCP sequences that I export the audio as a .wav (48 KHz), import the wav's into Adobe Audition and then export back as wav's and reimport into FCP.

One particular sequence, the audio is slightly out of sync once reimported into FCP, and as the clip goes on the sync gets worse. The audio remains 48KHz the whole time so I don't know what the problem is. In fact, the reimported audio is visibly 9 frame longer than it's source on the timeline.

Any suggestions?

Re: audio sync drift - fcp to adobe and back

by the way, it looks like I solved the issue. For some reason, the "Editing Timebase" of the sequence was off, listed at 25 [fps] instead of 29.97 [fps]. You can't change this setting apparently, so the only way was to create a new sequence with the correct timebase (I just dragged and dropped some footage to set automatically) and then copied and pasted the old sequence. I also had to re-export and re-import the audio files, but all was well after that.
