Wind noise frequency & how to reduce in post
on Jul 3, 2005 at 5:12:17 pm

We have a dialogue sequence in HD, with a crabber, there's boat noise and some wind noise, which I'd like to reduce. What's the best way to find the wind noise frequency to hopefully make it less objectionable. For tools, I'm working with FCP 5 and Sound track Pro.

thx..jw

Hey Jim,
Wind is very difficult to deal with because it isn't happening in one freq or band of freq's....it is very broadband and is constantly changing. and because of that, what you do to minimize wind noise will probably affect dialogue also.
Without hearing the sound, nobody can give you settings to start with. Try using a parametric EQ with a sweepable frequency control. Use the boost/cut control to drop the level 5 dB or so, then sweep the freq control through the selected range, and if you find someething that helps, adjust the bandwidth settings so that you affect the desired sounds as little as possible. Don't expect big improvements, you're kinda stuck. You could also try noise reduction software if you can get a long enough sample to use.

If you use ST Pro or a program like Sound Soap Pro, instead of trying to find a noise reduction setting that works for the entire clip, cut the clip into pieces. Cut the pieces so the sound you're trying to remove stays the same throughout the clip. You have a better chance of removing the bkg sound that way since it is more constant. After doing that (it can be very time consuming) you might want to add some bkg noise back in to mask the clip-to-clip changes in bkg sound in the processed clips.

If the wind is visually part of the scene, that would make it more acceptable as part of the sound track.
