Audio Help Requested

I'm not sure if I should post this msg here or in the Sound Forge forums. I know I'm not supposed to double post, so I'll go with here, where I've always received the most help.

I'm doing a VERY small and insignificant "movie," but I'm taking a lot of pride in it.
Unfortunately I screwed up about 20 seconds of audio and need an "Audio Pro's" help.
I fought with it for about 8 hours before finally giving up. I then handed it to two other editors (not to be confused with Audio Guys) who didn't have much luck either.

The problem is, I recorded my audio onto a Canon XH-A1 - but left it in HDV mode, rather than DV (where the audio would have been Uncompressed). So I'm getting a BIT of flange, but worse, I'm getting some unfortunate rumble.

I've tried (three 2-3 hour sessons) using NR2 in SF9, and could reduce the rumble, but at the expense of the quality of the voices.

I'm hoping some very kind Audio Expert will take pity on me and fix my audio woes. I promise, you'll get credit in the resulting flick.

If you feel you have the time and the pro chops necessary to make lemonade out of my lemons, please jot me a note at

Help me, Audio Pro Kenobe. You're my only hope!

Rumble is best removed with EQ. Since you're shooting mainly for the voices, feel free to drop frequencies below 200Hz. Getting rid of this and some of the high end may help the flange a little bit too, but don't expect miracles.

More than willing to help however as Chienworks says above and as you've noted HDV audio is not good, not good at all once you need to start adding gain.

The rumble may be fixable, the flange I'm far from confident about.

Given the amount of time you've expended on this already I'd seriously suggest it's time to consider doing ADR. Although not a trivial exercise the technical side of it is easily handled in Vegas.
