I'm trying to reduce some background, ambient noise (outside "room tone") from a wedding ceremony and I'm wondering if I can do this in FCP.
Noise print in STP would do a better job
Also, in another section, I have an airplane flying over a "moment of silence" (ironic?) and besides just lowering the volume, is there a filter that is good to use so that I don't eliminate all of the background noise when trying to minimize the plane?
Don't know what it sounds like so can't suggest a filter...instead take you backround noise from elsewher and add it while also eliminating the airplane
Staying within FCP, you might want to try the audio filter "Expander/Noise Gate".
It is located at Effects>Audio Filters>Final Cut Pro>Expander/Noise Gate.
It works by making loud sounds louder, and soft sounds quieter (eliminating the very low level noises), so that background noises will appear to be quieter. Like most audio filters, the success of the effect is often subjective.
Hope this helps

M the D,
I have had it with your incessant niceties, your intuitive diagnostic responses to inaccurate, insufficient questions is simply infuriating.
If you’re not careful, your kind, considerate and helpful contributions are going to give you a really good reputation.
And if it does…well…well…well it will give you just what you deserve.
For any ambient noise that is fairly consistent in its frequency range, such as an air conditioning system hum, can be reduced, if not effectively eliminated, by using the Notch Filter which you will find in Audio Filters>Final Cut.
By systematically searching through likely frequency ranges, and pinpointing the offending frequency, you will hear the noise reduce as you approach the right spot. Adjusting the "Q" will widen or narrow the range affected by the filter.
Depending on the hum frequency, it may or may not adversely affect the overall sound mix. If it does, add a Graphic Equalizer filter and use it to beef up nearby frequencies to help bring body back to the range you just robbed from while using the Notch Filter and try to find a happy medium.
The plane going by will be more difficult to deal with. The pitch will change due to the doppler effect will require a wide "Q" and even a happy medium may be difficult to find especially in the frequency range of a typical prop plane. The lower frequency rumble of a jet airliner would be easier to deal with because the frequency range is so far below vocal or music range.
I hope that helps.
