Need Help With Bad Wind

AlanC wrote on 9/17/2012, 2:01 PM
Owner of a bar/restaurant situated at Les gorges de l'Hérault near Saint-Guilhem-le-Désert in Southern France. He started a very entertaining conversation with us while we were having a drink. Unfortunately I only had my Sony pocket camera with me and the resulting wind noise drowns out most of what the guy was saying.

I'm hopeful that one of the audio experts on here will do me a big favour by reducing some of the wind so that we can hear more of what he is saying.

I would have a try with spectral analysis tools like audition.

Good luck...


F*c*k*ng mistral ;)

Hmm, thats pretty bad wind!

Easy things to say 'after' the event, - use a wind sock. That would have fixed 90% of the noise. That doesnt help now though.
However, the main problem i can hear (just on laptop speakers at the moment) is that the voice is being reduced, more like cut out, by the AGC of the audio circuit in the camera. So every time you get a wind blast, the rumble is so great the agc pulls the voice down to zero. Thats lost information!. The wind noise itself could be reduced i think but it would never be a great result.
There are some fabulous noise reduction apps out there like Izotope RX. That may help.

Computers can do all kinds of amazing things, fixing the wind noise in this video is not one of them. In fact, fixing wind noise in general is virtually impossible.

My wife says I need help with bad wind, too, but...oops, wrong forum.

There have been several times where the only windsock available to me was... well... one of my socks. Not the best thing, but it does work pretty well.

I don't know what you intend doing with this but if it's important to know what he's saying I'd make a transcription of it and put this over the clip as sub-titles. Pull down the audio level by 90%.

I was able to help some audio (not make it perfect) by using the Karaoke plugin in soundforge (I think it was soundforge) and reverse it so I was not removing the voice, but the extraneous noise. It made it usable, but that was about it.

I'll have a go at it with Rx shortly.
From my experience though such bad wind can cause the elements in the mics to overload / bottom out and then I don't know if much can be dones to fix it.

"From my experience though such bad wind can cause the elements in the mics to overload / bottom out"

That's exactly what happened, and any improvement will not be adequate.

Flat top audio is unrecoverable. This is yours.



Solution: Don't record audio outdoors in coastal areas.
;?)

Yes indeedy.

Pretty hard to do much with it. Rx can fix quite badly clipped audio, it can remove 50Hz "buzz" when it's more realistic to measure noise to signal ratio but this is something else.

The wind over the mic grille creates lots of frequencies that land right in the same spectrum as speech. That's further compounded by the camera's AGC.

Rx can use both HiQ notch filters and intelligent gates to wrangle noise, I used HiQ low cut to get rid of the rumble, another to get rid of the HF noise and then noise reduction with a mix of filtering and gating to get this. I really wouldn't say it's really better but at least it will not blow up your subs :(

Perhaps, just maybe, if I'd had a lot more time to put into it working on each section and each problem at a time a better outcome would be possible. I really didn't have the time to donate and I'm rather feeling it would be a lost cause.

Bob.

Thanks for your input everybody. The clip is just from my recent holiday in France and is just that, a clip from my holiday video. I was caught on the wrong foot when this guy started talking, he would make a good stand up comedian. I only had my pocket Sony W560 with me at the time, hence the poor picture quality, but wanted to record some of the conversation. The wind didn't sound anything like as bad at the time so I was disappointed when I played it back but never mind, it's not critical.

@farss
You obviously put a lot into that, my wife's hysterical laugh is now even clearer :~) thanks Bob. I'm hoping that if I use your improved audio track with the original video it may 'sound' even better.

Thanks

Alan

The clipped peak restoration in Forge might help some.

Thanks JJK but that's part of my problem, I don't have any decent audio tools.

I'm just going to say how proud I am to be a part of a group who can look at a title like "need help with bad wind" and resist the temptation to make fart jokes. (I know I can't be the only one who was wrestling with the urge to be immature here... ;-) )

Hi Alan, check this audio restoration of you video:

Not perfect but maybe works for you.

I use IzotopeRXII. Very wonderful tool.

Cheers

I wasn't exactly "resisting temptation" -- just recovering from the Chili Cookoff . .

I didn't resist, Laurence (see above), but often my brand of humor is lost on the masses.

Unless the noise can be nearly eliminated (and in this case it can't), then I'd suggest the idea of captions is probably best, and would be a professional solution to the problem.

Well you can do what I did in Vegas--remove the sound track and start over with a whole bunch of voice cuts from other people and make them work. The normal noise ambiants are a piece of cake. Expand the timeline out to max when you are syncing things up with the other peoples voices. You can spend hours and hours just looking for suitable replacement voices and tracks. I spent months just to see if I could do it. Sometimes with a good mike you can lip sync the new voice (your own) but it takes many takes to get the inflections and attitudes correct. The noise backgrounds you insert will make everything sound correct. Had my cousins (they were in a rock band in the 1960's) do a voice over (duet) on an old 45 rpm record of theirs (Imported to Forge) and it cam out pretty close. Also another song recorded on VHS. Of course the tiny nuances would have been rejected by the pros but I liked it.

@Erni, thanks for taking the time to work on this. I've compared your work with Bob's over and over and I have to say you have bothe done a remarkable job in reducing the wind noise but I think Bob's sounds slightly more natural. I'm just in the process of replacing the original audio track and I'll post the results as soon as.
