sound correction
hi guys im am doing a short film and have just recorded the narration, we used a small quiet room to record and I used a gun mic on my camera. Problem is its picked up a little or slight humming background noise, i could hear it with my ears but the mic picked it up. When in final cut pro is there an audio filter that can make the narrators voice come through and the background slight hum gone?
Cheers for your time

I’d suggest using SoundTrack Pro to reduce the noise. It’s cool because you can choose a point where all you hear is the noise, then tell it to try to reduce that noise throughout the whole clip.

If you have Adobe CS3 or CS4, you can remove the noise via Soundbooth. It has a unique 3D view of audio and it allows you to identify and reduce noise (like hum, hiss, HVAC, etc) better than any other audio products. I’m an old audio guy and used to sell ProTools quite a bit, so hopefully I qualify what I’m saying (even though I’m an Adobe guy)

Really? Better than CEDAR?

thanks guys not sure if i have sound cut pro and dont have adobe, is there no filter in fcp that can help me out?

Your best bet is to play with eq filters and see if you can filter out the frequency that the noise is coming from. Sometimes this works and other times it effects the dialogue too much.

To the best of my knowledge, CEDAR products do not offer the spectral frequency views that Soundbooth does. Even if it did, I didn’t see any prices lower than $2500 (most were over $10k) and little or no Mac, so I don’t see them as being valid tools for most editors.

Apply a notch filter (AKA a parametric EQ), set the Q (width of freq.) very small, set the amplitude very high and then sweep the freq range to isolate the offending frequency. Then take the amplitude control and take it down all the way. If it’s electrical hum, it’s usually around 60Hz.

I occasionally get hum from the camera transport picked up by the camera mic. I’ve found that if I use the Parametric EQ filter I can get rid of it. In my particular situation I have to set the frequency to 3280 Hz, set the gain to -20 dB and the Q to 3. You’ll probably have to tweek the settings a little, but this should get you in the ballpark.
