RE: Audio filter FCP 5 for BG refrigerator hum

Looking for specifics for masking or removing BG hum of refrigerator in time line editing. Several clips of same subject, would paste for all. Is there a specific filter in FCP 5, or in Sound Track Pro?

load it into soundtrack pro, "set noise print", then denoise the tracks with the hum.

The slightly expanded version of that is to select a section with refrigerator only and use that to set the noise print. The software will try to subtract everything in this print from the show. And it will only do it with clips that have exactly the same noise. If you switch microphones, you need another noise print.

This process is serious magic, so don't bet the farm on it working perfectly. If something in the Kelvinator noise happens to be the same as one of the human voices, the voice will get seriously bubbly. That's why there are tuning tools for this process. The version of this tool in Adobe Audition has multiple tuning tools.

It also works best when the voices are very much louder than the fridge.
