After you import the wave, if you let BB use it's auto chord wizard, it will attempt to diagnose the correct chords and the tempo to match the song.

Depending on the complexity of the music..... BB ACW can either nail this amazingly well or not at all. I've had it go both ways in the past. In several songs ACW got the chords and tempo really close..... and on others I had to take the time to reconstruct the song because ACW was totally thrown by the chords and rhythm.

It is necessary to tell BB where the song starts. It will take a few tries normally to get it right.

I've had people send me tracks asking for a fiddle or a sax or some other instrument in a song they are working on. Using BB and ACW is how I accommodate them. Since they almost never have BB or send midi tracks, I need to be able to diagnose the audio tracks and ACW is the first choice in tools to do that job.
