That was successful and allowed a WAV file to be imported successfully.

After getting RB back up and WAV imported, ran *Analyze* to get chords from the audio file. Next ran *Analyze* in BIAB on the same WAV file. The differences in BIAB vs RB are significant.

Original Key = Bm
2 bars Bm7 A/B and 2 bars Em7 D/E

Comparison of BIAB AND REALBAND
Results of RB: B D/F# F#m Bm7
NO REPEATS
Results of BIAB: B F#m F#m B7

Neither results are what is expected and are not close enough to use as Lead Sheets!

My question is this. Are either BIAB or RB analysis reliable as to the accuracy of CHORDS displayed in ACW? How does one use this feature in either program with any degree of confidence?
Regardless which version of the ACW used, BIAB or RB, both require accurate setting of Bar 1 by the user. Bar 1 is not necessarily the beginning of the song. If you did not take this step, the silence at the beginning of the audio is factored into the analysis and the ACW is also not properly calibrated to align with the song's bars. Without setting Bar 1, the ACW analysis can't achieve an accurate analysis of tempo or chord progression.

I've posted two screen shots of an audio file to be analyzed in BIAB with Bar 1 set wrong and the other set correctly and also with lead-in notes prior to Bar 1.
