Normalize sound Premiere Pro CS 4

Question

Hi.
I have a lot of clips in my sequence, where the audio is too low or too high, how I normalize them at one step.?

Answer 1

I'm not a heavy Sound Booth user because I come from a pro audio background and tend to lean on those tools. That said, when I need to process audio for an entire track, typically what I do is export as audio only, bring it up in my audio app (Sound Booth would probably work just fine), clean it up, save it out, and then import the edited audio track back in.
By the way, when you're normalizing, you might first want to do a pass with a limiter to chop off the highest peaks. Since normalizing only scoots up stuff by the distance of the very highest peak to 0db (or whatever ceiling you set), one stray spike in volume can prevent the rest of the audio from being boosted.
If you look at your wave form, you'll doubtless see that most of the energy resides within a particular range, and then you have some thin spikes here and there. Let's say that the bulk of the energy resides from -6db down. If you run the limiter to make a 6db reduction, it snips off the errant peaks. Then, when you normalize, you'll get the 6db boost across the board.
Going too far in this direction with a limiter will start to give you some distortion, so it's best to experiment a couple of times on a copy until you've got the hang of it. The end result will be more consistent audio across the board as well as enhanced levels for you to work with once you're back in PPro.
If you have it, Adobe Audition is a great tool for this kind of work. If not, I'm reasonably sure you can accomplish it with Sound Booth.
Hope this helps,
