Could you elaborate on this compression a bit? I'm not new to Vegas or sound recording, but, except for a very slight bit of reverb, I generally do not alter vocal wave files - not because I'm a purist at all, just because I don't usually like the result I get.
What plugin would you use to add the compression?
BTW, most of my recording is of either classical vocalists or folk singers.
You may try expermenting with the Wave Hammer plug-in... but with very lite settings. More is usually not better.
Wave Hammer has both a compressor stage and a second peak limiter/volume maximizer stage. Try setting the maximizer stage output level to about -0.01 to to -3.0 and then lower the threshhold to obtain about 3 or 4dB of gain reduction on the loudest peaks. This is usually placed last in any effects chain. Any comp/limiting will bring out the room, ambient sound and other noise more, so keep that in mind.
I hope your not using the AGC on the camera. If your interested in better audio, There are many things to consider; mics, mic- preamps, mic placement., ect., ect., ect. The first thing, Canon cameras are notorious for very poor sound quality. To be blunt, the A/D converters suck, and forget about the onboard mic and preamp. For music recording, record the sound on something better than the camcorder if possible. Of coarse this means wild-syncing the sound and picture later on in post, since the Cannons' and other prosumer camcorders have no TC out and can't read or jamsync.
