Weird Hum/Buzz in Audio - How to Remove?
 

I recorded a conference session regarding RF engineering/hacking and due to some of the gear they were running for a demo, there's a weird buzzing in the resulting audio my camera captured.

I've uploaded a sample here: Dropbox - robert_output_sample.wav - Simplify your life (.WAV approx 3mb) and I'm not sure how to remove it without impacting sound quality. Anyone have any clues as to how I can remove it? (I'm using Adobe Premiere CS5.5 to edit). I've tried using a few audio effects on the audio track, but don't really know what I'm doing and haven't had any luck :(

EDIT: I forgot to mention, this is in Adobe Audition CS5.5. I assumed you had one of Adobes Suites.

Have you tried capturing a noise print and applying Noise Reduction (process)? I gave it a quick go on your clip and had good results.

Find a gap where there's no voice over, highlight it, click Effects -> Noise Reduction / Restoration -> Capture Noise Print. Deselect all (Edit -> Select -> Deselect All). Apply the noise reduction (Effects -> Noise Reduction / Restoration -> Noise Reduction (process). Click Apply in the window. Just go with the defaults and see how you like it. After that it's playing with the settings.

For instance, in the sample you uploaded there's a section at the 2.4 through 2.7 second mark that worked great in my quick test.
