Audio clean up in post...

I posted this question in the FCP forum but I figure I would ask here too.

Is there a way maybe using one of the EQ's or effects either Apple or FCP HD to try to eliminate background noise? I have an interview that I shot and we used a stick mic which was right at the person's mouth but you can hear still hear a lot of noise in the background. The noise was from the event that I was shooting. I was wondering if I possibly imported the wrong channel of audio because listening to the raw audio on my external monitor sounds a little better than what I have sitting on the timeline but you still hear the background noise. I am not trying to eliminate all together just trying to do something to make it less noticeable and put the focus on the interview mic without peaking my levels. I have music playing underneath the sound byte so I have to watch my levels that they don't peak but I am trying to get rid of some of that background noise. It sounds like all 3 (main audio, music, and background noise is all competing with each other. I tried killing the music all together but then it makes the interview sound worse because of the background noise. I know now to use a directional mic next time instead of the omni directional.

If you recorded it, you can't make it go away, unless it's tape his, or a specific frequency that you can notch out. If it's just general background walla that you are tryng to get rid of, you are out of luck.

Don't give up though. I'd try a little EQ (parametric) try to export the audio to a stand alone audio editor like Digital performer and try to clean it there.

That won't do anything but boost or cut specific frequencies. It may help a tiny bit, but certainly won't make it usable. I've had to deal with this before, and I ended up looping the scene.

Dave's exactly right, you can make marginal footage slightly clearer and maybe notch out an annoying sound but I would call it a 5 percent improvement at best (so think of your audio on a 10 scale and add .5 to it).

If ADR is not an option you can use the reality show backup standard and put some subtitles on the clip.

Good luck.
