And if it shows 0 try it on portions of the selection. Sometimes a very narrow sound like someone bumping something or some other click can be the loudest sound and keep normalize from doing what you want. If there is an extraneous sound doing that you might be able either to cut it out or use hard limiter or click removal on it. To find the loudest point I either use the Peak Finder plug-in (which you can get from the plug-ins page). It puts a label at the position of the loudest sound in the selection whose text is the peak amplitude in DB. If I don't use Peak Finder, I select the first half. If Amplify doesn't show 0 for it, I then try the second half. if Amplify shows 0 for it I then try the first half of that half, etc. until I narrow down the position. Save/Restore Region (Alt+e, g and Alt+e, n) may be helpful when doing this. I might also set a label on the original selection so I can find it again when I'm done. If the label track is selected, the selection range of the label will adjust if you edit the sound, whereas the stored region will not.

I make recordings with a Sansa Clip Plus MP3 player/recorder, and pressing the start and stop buttons produces a click at -6DB when the audio is at less than -20DB. I often use the hard limiter to limit the click to the amplitude of the surrounding audio. (Or I did with 2.1.0-- there is a new limiter plug-in in 2.1.1 with more features, but it won't let me limit that much, maybe only 10DB. Click removal sometimes also helps.) Sometimes it doesn't sound too good, but the compressor doesn't have to deal with it, and sometimes it doesn't sound much different.

Of course if it's music and the cause is a peak in it that may not help, although I bet one of the settings of the new limiter might be better than the old one.

I got the Decrease/Increase Gain shortcut keys to work, but I still can't
get the Normalize dialogue to work as expected.

What value does the "Amplify" effect propose?

If it is zero, you'll already normalized and should use the Limiter in
order to increase the volume further.
Set the gain slider back to zero, otherwise the exported audio will clip.


It might be that you'll also need some compression if softer parts are
barely audible - but this can also increase the noise.

If you leave configurations as they are, the sound should be braught to
0 db.

Please make shure the check box to normalize the amplitude is checked.

Hello.

Are you shure your track is selected?

I ask you that, because some of the effects can be previewed even when
the
track is not selected. I tryed in my system. Gain, pan and normalizing
may
have that behaviour. If the track is selected, then all effects should
work
fine. Best regards.

Hi, it's Annabelle.
I'm trying to normalize a sound that is slightly too soft in volume,
but when I work with the Normalize command, I set it to 0.0. When I
press "Preview" it works, but when I press "OK", nothing's changed. I
also tried the gain shortcut keys (- and =), but even those don't
produce results, in other words, the volume remains the same. What do
I do next? How would I fix it?
