Anyone know of a good article on this audio filter? Or at least tell me this: is there a specific process for making the adjustments, or is it trial and error?
 
Allot of it is trial and error. But all your doing is controlling different frecquency's of the audio file. So you can bring out the lows or the highs or make it sound more even.
 
You should try using Soundtrack Pro (if you have FCP 5 studio). There is much better EQ stuff in there and it is easier to control the audio filters.
 
Mench, one example is some sort of machine that was running outside. Sounds almost like an electric fan, but it's hard for me to tell whether the freq. is above or below the speaker's voice. I guess you just keep trying various things to get max. voice and min. machine noise?
 
A general technique for eliminating sounds is to take one of your eq bands, and set the Q to be fairly narrow, then boost the band all the way up. Then sweep the frequency back and forth until you hear the offending sound more clearly. Now that you have identified it, just pull it down. At this point you can mess with the Q and the amount of subtractive eq. You will find that generally there is only so much you can do without inducing severe artifacts in the sound.

I'm not really sure if the FCP 3-band eq has these features, you might be better off with some sort of parametric eq if it is available.
 
In that case I'd use a notch filter to isolate it... drop that puppy on and crank the notch all the way UP. Loop the playback so it plays over and over. Then slide it up and down the range until it POPS at you. Then, notch it out and it will give you a good area to bring out of the 3band. But leave the notch on there too.

EDIT - beat to the punch again! ugh.
 
Also try the "Reduce Noise" option in Soundtrack Pro. You can usually get some really good results with it.
