Re: avi file
If you split out the audio channel (try www.dvdrhelp.com for tips), then Exact Audio Copy has one of the best spectral subtraction noise filters there is, and it's postcardware!
www.exactaudiocopy.org

To use the filter, you need to be able to find a representative sample of NOISE ONLY, the same noise that you are trying to reduce - you only need a few 10ths of a second, but a larger sample is more accurate.

The result is BETTER, MUCH BETTER than any noise gate - in a test, I actually got audibility (I'd call it communications quality) of something that I'd deliberately swamped in PC fan noise
