Audio track background Hum

[Steven Talley]

If the hum is consistent and you can capture a sample (1-3 seconds) of it, then use it to remove the offending sound in noise reduction.

Steven,

Could you be more specific? I’m having a problem with the audio of some footage where the interviewee seems to have been in a room with the AC on or a refrigerator on…

I think I only have just a few frames of the offending room sound.

How do I use the isolated sound to specify the sound to remove?

Much appreciated.

— A quick update — I clipped out the room sound fragment and looped it at the end of my clip, which gave me the sample for the offending sound. 🙂

Now, to get rid of the hollow echoing ambient room sound. The interviewee was shot against a wall, using only the built-in mic, so she’s too far away for a robust sound, and the hard wall makes the sound bounce all over.

Any Soundbooth filters for this type of problem?
