How the audio file gets into BIAB makes a difference with BIAB settings and what the ACW will analyze.

Importing audio files do not adjust the number of bars of the Chord Sheet to match the length of the audio file. If audio file is 20 bars then that's all the bars that will be analyzed by the ACW even if there are more bars to the length of the imported audio file. Scroll to the end of the WAV form in the Audio Edit Window will show how many bars to set the Chord Sheet to.

The default number of Chord Sheet bars is 32 (unless you've changed the default in preferences) The number of bars of the Chord Sheet is what will be analyzed by the ACW regardless the length of the imported audio file is imported and by not adjusting the Chord Sheet bars will give the results similar to your post of the ACW ending early. When you import an audio file, you must check the audio file length and manually adjust the bars of the Chord Sheet to the audio file length plus ending bars. In the new ACW, the Chord sheet, Mixer and Audio Edit Window are integrated with each other.

File | Open audio and
File | Open audio with chords and
Open (F3)

Opening audio files with any of these commands does adjust the number of bars of the Chord Sheet to match the length of the audio file displayed in the Audio Edit Window. If audio file is 80 bars then that's the bars that will be analyzed by the ACW.
