Removing wind noise with Sound Forge
on Jun 24, 2014 at 12:23:33 pm

VMS 12 & SF studio 10

We take quite a lot of video while on on boat waterskiing/ wakeboarding etc.
Nothing professional, video quality is full HD with stereo audio,

The camera picks up a lot of wind noise (plus of course engine noise) ... anybody have any steps for reducing the wind noise in Sound Forge.

The Help files say to use Sony FX Audio Restoration ... but really only gives details on reducing clicks & pops on vinyl recordings.
The only preset included is 'general restoration' anybody have a preset for wind noise, or a guide as to what sliders to adjust.

I also have the seperate purchase Sony Noise Reduction plugin ... this has ability to take noise prints, and again only has basic preset included.

Wind noise is broadband and contains every frequency in the spectrum all at once. It is also constantly changing which makes taking samples difficult. In sort, it's almost impossible to remove but very easy to prevent. Get a "Wind Muff" for your mic (often referred to as a "dead cat"). They come in all sizes and do a great job.

The best you can do now is roll off the lower frequencies with an EQ. You can also try taking small samples when it is consistent but nothing can remove the wind in post production because it is full frequency and constantly changing.

No separate mic ... built into body of camera unfortunately.
I'll try playing with Low pass ...

[Rick Hughes] "No separate mic ... built into body of camera unfortunately."
They have wind muffs for built-in mics. It has an elastic that stretches around the camera body. The bottom line is that you need to cover the mic to protect it from the wind. You can make something yourself but you need to cover it. You won't be able to remove it in post.

Here is a video on how to built one yourself:





Get creative! ;-)
