Sorry if my question is basic. I've read the manual and I'm still a bit unsure what to do. I'm trying to combine two audio tracks . . . one is very loud, the other very soft. What's the best way (losing the least quality) of bringing them to the same sound level?

As to the subject line -- normalize is just amplify to a specific
maximum rather than a particular amount. For example, if you normalize
to 99% of full scale, AP will calculate the maximum value of your
signal, figure out how much you need to amplify to make the signal 99%
and then amplify by that amount.

As a first try, I would normalize both tracks to 99% and see what
happens. If that is good enough, go with it. If it isn't, go to the
forums, search on "volume" and pick a post by me and you can get a very
complete discussion.

Note, before doing any of this, I would run "statistics" on your loud
track to make sure that you don't have clipped samples. Also, you might
want to check your quiet sample to see if there are a some outlier
points that are too large.
