Best way to reduce wind noise in Resolve?

PostFri Jul 06, 2018 4:25 pm

I'm having a hard time finding tutorials on reducing wind noise in Resolve. I mostly find vids for noise reduction in general but nothing that really tackles wind.

Does anyone have a walkthrough they can share about reducing wind noise?

Thanks in advance.

I think there is no satisfactory way to remove wind noise, wind noise is not additive to the original sound instead it damages it.

The best way is always to prevent wind noise by using a "dead cat" or even better a blimp.

Wind is something you remove in production, not in post.

Rx6 has a module for it ('de-wind'). Haven't tried it, but there should be a free trial.

You could also try the v15 noise reduction plugin, using the learning feature on any isolated stretch of wind in the clip, and see what happens. Wouldn't hope for much -- constant change and randomness makes wind hard to remove -- but worth a try.

I did have a dead cat on my mic. But, there was still a little wind left.

Thanks.

If it's really only a little wind, an adequate combination of Spectral De-noise, De-wind and Dialog Isolate in RX6 will give you usable results.
Some testing to get the optimal sequence and settings will be necessary.

Agree with previous poster - the only effective way to get rid of wind noise is to do it while you are recording - with a blimp if the wind is very light and the addition of a dead cat if the wind picks up.
The effectiveness of the blimp depends on the amount of dead air between the mic and the inside of the blimp, more is better.
The foam types, even with dead cats over them are not any use in other than the lightest flutter. I only use them on a boom indoors to cut out induced wind from boom movement, or if the mic is stationary, then from slight currents from warm/cold air drafts. Actually I use the foam that came with my DPA short shotgun all the time indoors. It is really good indoors and it is lightweight and discrete. Outdoors I always use a Rycote blimp, 99% of the time with a dead cat.

You can try Rx6 de-wind along with a pass of de-rustle as mentioned above and speaking from experience all I can say is that it works on most basic wind noise as the rumble sits at the lower end of the spectrum, the meat of human voice is a little above. Rx6 also uses some machine learning to tackle wind and rustle. I was lucky with some bad windnoise, Rx6 just made the audio usable. But it was a documentary, may not work for Dialog and you would have to get an ADR done.
I also saw some example of Machine learning demo that just reconstructs the line like magic. I think the demo was by Adobe.

Is it possible for you to do the ADR, Resolve now has one of the best ADR engines in the industry.
