Boosting Audio in V4 Beyond +12dB?

ken c wrote on 7/23/2005, 9:25 PM

Hi - quick question.. for some of my seminar audio footage, I need to boost the audio beyond what I can do (apparently) in vegas4 with the volume slider .. eg +12dB... any ideas how to get more gain on the audio?

What I've been doing is exporting .wavs, then using cool edit pro (great basic tool) to amplify with 10db boosts, or 6db etc... this works great, but it's a hassle to have to use different apps..

any tips on how to boost gain in V4 timeline beyond simply moving the volume slider to +12dB, and/or adding an audio envelope and lifting it to the +6db?

thx much,

ken

(btw the seminar rocked, see vid testimonials at www.megaseminar.com)...

Normalize, compressor, wave hammer.

2 very simple ways are.
1) just copy past an exact copy of the audio to another track directly below it.
2) rightclick on t
e audio track (not the audio) and insert a volume envelope. you can then up the volume with the left slider and the envelope.

Save yourself some work and do the normalize first, it's the quickest and you have nothing to lose with it.

If normalize doesn't boost enough, you have sudden peaks somewhere (from mic handling, etc.) that should be removed, replaced with roomtone or equivalent, or treated individually anyway.

If you just up the gain enough overall through any of the methods mentioned here, then you'll probably clip any transients and make them sound really bad, after which you need to treat them anyway.

If you need to boost the gain a lot, you'll probably get a fair amount of noise, which can be treated in a number of ways in Vegas too.

Were it me, I'd follow Coursedesign's suggestion. Either cut out, trim, or use volume envelopes to kill any transients that are keeping it from normalizing to a usable level. Cutting them out completely would likely help. There is a normalizing script that will do all audio on the timeline.
Hopefully you got some ambient noise recorded on there somewhere that can be used to fill a hole or edit point?

Great to hear the helpful tips re volume envelopes and normalizing, appreciate it.. will do re ambient for fills, good idea... thx as always... so much to learn.. :P

Wave Hammer can solve problems with spikes.
