I don't use Audacity a lot but do quite a bit of sound editing. If "Normalize"
isn't working on a selected part of the data, I wonder if there might be
something in the signal that is fooling the process that isn't real evident by
listening. For example, low air conditioner rumble or turntable rumble in the
case of recording a record can be much louder than it seems likely by
listening, especially on small speakers. Some microphones will produce a lot
of low frequency energy when they are picked up or moved. A high frequency
sound can also cause this to happen. Also, depending upon one's settings, one
loud sound in the selection will affect what "Normalize" will see as the peak
level. One badly popped "p" can even cause a problem.
One trick I have used is to play the selection at double speed and half speed
to be certain that there isn't a sound of which I am not aware. The downside
of amplifying if Normalize isn't working is that if there is an undetected
sound, it may get pushed over the 0 DB point. Sorry if all of this is obvious.
Best regards,
Steve Jacobson

I suspect that Amplify is your only option. I have been playing with
some of the fade tools in the Effects Menu and so far have not found
anything relevant.

Hi,
Can I adjust gain only on a portion of a track? I know that I can use
normalice or ampliphy, but, something equivalent to shift g to adjust
gain only for the selection?
