Audio Editing WIth Final Cut Express

Its far from perfect but if you need to retain audio with a lot of wind noise on a video clip, try this filter in Final Cut Express - by David R. Beebe

I mostly replace the audio with music but sometimes you want to keep some or all of it. Wind noise is difficult to remove. Use Audio Filters -> Apple -> AU Graphic EQ and drag sliders below 100-200 hz. to get rid of most wind noise.
