Yeah, and is a good suggestion. this is the situation:
I recorded a live concert using the ca-11 mics, ca-9200 preamp, with an
Olympus ls-14. Now I'm working with the recording but I configured the
levels too low on the preamp, and when I say low I say really low.
However, the thing is if someone scream on the mic (for example, if the
frontman say "scream for me santiago") that scream generates a click, so
when I try to normalize it fails because that scream generates a loud
click. The thing is it is a concert of about thwo hours and these kind
of problems only ocurs thwo or three times, and in a context of a
bootleg not are too notorious. So, I think I'll try with your suggestion
with peak meter.
the reason to not apply gain for all the track, and why asked for
something equivalent to shift g only for a portion of a track is that
when I started to record I changed levels, and now I need to adjust
these to the average levels of the song (that changes happened only on
the first 5 mins of the track, and the levels at the rest of the 2 hours
are the same... low, but the same).

Steve, that may all sound obvious but the issues you raised are traps for young players. I had an ongoing discussion with a brother about this a few years ago while he grumbled that the level was too low and insisted there was nothing that should prevent a higher level. I eventually persuaded him to follow the below suggestion and, would you believe it, there was one loud click.
Audacity has a few useful tools. Having made a selection, going into the Amplify dialog will tell you how much below 0db the loudest point is. But you then have to track down the loud point(s).
I like Peak Finder RFT in the Analyse Menu. It will find the peaks and put a label at each of them. You can then decide, depending on circumstances whether to delete the offending sound or lower its level.

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?
