Wind noise reduction

How can I remove/reduce the wind noise on my audio track?
I looked at the track EQ with the graph, but can't hear much difference. Still too noisy. Crossing the Atlantic in Dec is an audio challenge......I know I can remove the original sound track and add a better audio portion, but I would like to get use to audio fx... never use them.....
Thanks anyone....

Wind is nearly impossible to remove, sorry. It is very broadband noise with constant fluctuations. There isn't anything constant to "grab on to" for any effects or filters to be able to use when trying to remove it.

About the only thing you can do is to emphasize what you want to keep. Voices are usually rather narrow band, often in the 300 to 2Khz range. Using graphic EQ to boost this range while dropping everything else can bring the voices out some. The wind noise in this range will also be increased, but if you can eliminate the ranges that don't contain voice then it will help. The result may sound somewhat tinny, but you should at least be able to make out what was being said.

You can give filters a better chance by applying them to short sections at a time (reduce the variation), but it's very tedious and you'll never get perfect results.

I know it's too late for footage you already have on tape, but for future recordings, check your camera's sound options. Many have a wind noise reduction feature you can turn on before recording.

Thank to all.....
Well I guess I will have to fudge it....
But for the future.... I did use the wind reduction on the camera.... to no avail.... (I even try to cover the micro with a thick layer of kleenex.... that's all I had available....) but is there another way... a special micro or? I live on a windy coast and do a lot of boating.... something not too big for obvious reasons....

An open-cell foam windscreen works wonders. If you can find one that fits over your mic that would help a lot. If the mic is inside the body of the camcorder then perhaps you can find a piece of foam that you can tape to the surface of the camera.

Thanks Chienworks.... any foam would work? how thick?

The best windscreens i've used were a very dense foam about 1/2" thick. You could always buy a pro grade windscreen at the local audio equipment supply store and cut a piece out of it.
