Does anybody have any suggestions for minimizing a buzzing sound that's only in one channel? Turns out it was caused by a bad XLR cable.
I knew something was wrong because my left and right knobs were way out of whack with each other, but due to time constraints I couldn't investigate to find out why and had to just let it go and hope for the best.
Any ideas for fixing something like this in either Audacity or SoundForge would be greatly appreciated!

Yes johnfitz, you might be in luck..
I have had adequate success with Sound Forge 11's new "Sony Noise Reduction". Niiiiice improvement over the previous tool.
Highlight a 10 second sample and get a "Noiseprint" of the offending buzz, then go back and highlight the complete noisy channel, and apply the tool.
If you have two noisy channels, get a noiseprint of each one, and apply the tool to each one separately, of course.
:bigsmile:

Thanks a lot!
I'll give it a try.
Appreciate your help!

If that doesn't work out, you can obviously just copy/paste the good channel over the bad one, but the ending result will be MONO! Myself and others have had success adding a slight delay or something to the overall MONO mix, to make it sound more "stereo" :)
Best of luck! Id love to hear the end result ;)

I just did this exact thing to a quiet show where one channel had a buzz / white noise, sounds like pretty much what happened to you. It was one set in the middle of a festival and not even the first or last set of the day but only that one had the issue. I chalked it up to a loose connection or cable as well, although I'm not sure what caused it.
I tried to remove the buzz with several methods in Audacity but replacing the bad channel with the good sounded WAY better. I've done this a few times, and like Bean says, if you add a slight delay to one (a couple of milliseconds is all it takes) and also EQ one slightly differently (I usually take a couple of dB's of bass out of one channel), it does sound better than just a straight mono converted to stereo, IMO. I can post or send you samples of the comparison if it would help - just shoot me a PM.

Unfortunately this option really won't work in this situation, but thanks though.
It was an acoustic trio that was playing around a single mic and I set my mics up basically right on top of theirs, roughly 3 feet from the performers.
By pasting channels I would lose the true stereo imaging and dynamics of the 3 instruments as they moved around, traded places, got closer and further from the mics, etc.
I'm hoping to have some time this weekend to play around with Capnhook's suggestion...

Ahh gotcha! Thought you were in the crowd! Well, you def mentioned a situation where copy/paste WONT suffice, because the players were centered around your mics so closely :( Also, Tascam released a MONO/POLY[Stereo] Converter for use with their recorders that can do both, like the 70d! You can convert Mono>Stereo, and vice versa! Not sure if that would help remedy the situation or not? But def a cool tool that might get some use!

Also, I'm pretty sure that SF has a buzz/noise reduction feature specifically for this! I'm about 99.99% sure that WaveLab 6.11, that I use, has that feature! I would bet the farm that SF/WL/Audacity has something that helps remedy the situation!

I use Izotope RX5 Advanced for noise reduction. If you can't get good results with SF I am happy to help you out.

What Ronmac said, just host a Dropbox (or other file hosting service) link here and one of use can take a stab with RX5 Advanced. Good to see you here John.
Cheers!
