I think Glen is right about the Adjust Audio Track being for an associated WAV.

On the other topic, I find a difference when using the Normalize as opposed to the Boost All Files function. In an earlier post, this was discussed. Matt pointed out that one loud drum hit can affect the entire Normalize process which changed my opinion about using it from BIAB.

Boost All Files Amplitude seems to do the trick. I tried to hear the difference when boosting by 12 and 24. Both seem to produce the same output volume. Perhaps it is the built-in limiter kicking in. I can't detect any compression if it is using such. Further testing is on my list.
