Wind Removal

I am helping my girlfriend make a tutorial video for school, we filmed outside in a grassy and usually calm area, however on the day of filming there were harsh winds that make the audio completly terrible. Is there any way to remove the sound of wind from the audio track? There is no way we could refilm so what we have is currently all we can get. 
Thank you.

Have you tried the option to "Enable noise removal:?

Click the Audio tab and have a play.

Ya, I had a similar problem when doing an interview in a convention hall. I tried downloading a separate audio editing app (export fix, and reimport) but it didn't really help much. the more you try to fix it the worse it starts to get. Unfortunately, once the sound is recorded its hard to take out ambient noise. I've done a lot of studio work and the key is to pay attention to getting that good recording with a lapel mic or something like it, and do as much as you can to handle the wind/noise problem. So sorry to not be able to help much. But live and learn, I've had to the hard way. Cebron PS: The advice on the enable noise removal does do a little bit.

regarding the "windy" background noise, ... 3 approaches

1

silence all space between spoken words; the overall sound should be better

wind may still be heard on top of the narration

2

re-narrate everything using Voice Narration or something like free Audacity; do so in short segments, which will make it easier to match the original duration and cadence, and use in-place of the original audio; if you have problems matching the original duration of a spoken section, tweak the duration of the underlying video section using clip speed adjustments

a more tedious approach, but results can be excellent

3

add closed captions that mirror the spoken narration

can be effective with certain types of videos

My goal here is not to steer anyone away from a TechSmith product to others. But in some cases it may be helpful. Additionally, how easy something may be is always subjective too.

Adobe Soundbooth seems to have some amazing capabilities in the right hands. I know companies always want to showcase features that may or may not work as easily as shown or even as advertised, but I've used it to very effectively remove an annoying 60 cycle hum from a video.

And I know Adobe always demonstrates how they have a recording of a lecture or speech in a large venue and a cel phone goes off. And they are able to somehow isolate and remove only the noise print of the cel phone, leaving behind the speech or lecture. I've tried something similar, and that particular feature seems to require skills I don't have. I'm sure it's possible to do, but it wasn't easy and it escaped me.

I believe what is needed for this is what is called spectral editing. It is VERY advanced audio editing. An understanding of frequencies--what they sound like and what they look like--is required. Audacity has spectral editing capabilities, but it is really primitive when you compare it to Sony's latest spectral editing software. There might be others out there even more sophisticated, I am just not aware of them.

Hi,
I am pretty much along the line of kayakman: I would just bite the bullet and rerecord the audio as the video plays. If you had a script, it will be easy to do - using voice narration in Camtasia Studio.

If no script, then you can listen to your audio file a couple of times then wing it like you did for your original take. (Or, take notes to keep you on track.)

Or, as others have recommended, record the new audio in another program like Audacity.

You could spend hours trying to fix and tweak, but with a problem like wind, it's better to go for a do-over.
