So when I manually correct the timing offset at the beginning, it continues to lag more and more over time. The audio is in the proper key, but it has (somehow) been stretched.

Also...I imported a previous mix of the entire song, which is 118 BPM, into BiaB and ran the ACW Auto Analysis, and it mapped the song as 120 BPM. Hmmm.

Anyway, I don't have a solution, just laying out some interesting findings...

THANKS to those who have pitched in so far!
I'm not sure you're correct. It looks like your screen shot is taken from Studio One? If that's not correct, it still appears to be taken from the DAW you use.

If that's correct, there's an issue with your conclusion. It seems you're saying the bottom audio file imported into your DAW from BIAB is the time-stretched audio done by the ACW. If that's correct, then yes, it is expected behavior for there to be an offset that changes over time. BIAB rounds bpm to a whole whereas DAWs are quite a bit more accurate. It appears to me in the screen shot the waves reach a certain level of offset and stabilize and I attribute that to be from BIAB wav being time stretched to a different bpm and also to the inherit difference of the DAW tempo accuracy to BIAB's rounded tempo.

I'll only comment on the BIAB images posted earlier and that is a timing offset, or import placement issue. Doesn't matter which, the fix is the same.
If the ACW does an accurate analysis, whether manual or not, or even if it's not accurate, the BIAB Chord sheet should accurately follow the tempo template the ACW creates.
