How to boost my audio WAAAAAY up?

Here's what I screwed up... Was flying in a small twin engine float plane, and turned the audio levels down to almost zero so I could get some clean sound.

Plane landed. I got out, shot a quick interview. Oh, did I remember to turn the audio up? No, of course not.

On the timeline, if I move the Vol. to +12db and put a volume enveloppe in set on max... and turn my speakers to 11... I can hear it. Is there any way I can boost the volume even more (speakers on 8, I can't hear it anymore). Should I just render the clip out, bring it back in, and boost the audio again, or is there a way I can bring it up even more? Quality isn't critical, neither is the interview, but I would like to have it if I can save it.

Thanks!

This is when you'd use Normalize, which (in Vegas) will set your overall clip volume so that the loudest peak will be at a preset number, I think the default pref is -0.1db.

Right click on the audio clip, pull down to Switches | Normalize. Done.

To quickly set this switch on multiple clips, copy the Normalized clip, select all the clips you want Normalized, right-click on one of them, and select Paste Event Attributes.

And then there are scripts...

for the future, if this should everhappen again, you can split the track and use the Volume FX or Amplitude modulation FX, you can use a volume envelope, you can use a bus and raise the level or place the offending clip on a seperate track and use the level adjusment in the header or any combination of these.

In this case, I agree Normalize would be the option to use. The bad news is that ALL sound will be increased by the specified amount - including the underlying noise level.

Other option would be to open the the audio in an external editor an use normalize or other methods and run some noise removal if amplifying adds considerable noise.
