Did you recently set the switch to 'normalize' your song? Based on whether it was one song or all songs ... for one song you might consider that you elected to 'normalize' it. After I had blanketly normalized about eight songs, I then found that the overall volume was way too low. Of course, it is a possibility that you set a global switch somewhere to tell BiaB to normalize all of your songs.

Can anyone help me tell him where there might be a setting that does this?
