Need to remove wind interfierence

donp wrote on 1/4/2004, 11:11 AM
I have a tape I'm going to process through Vegas 4d. It was from a friends trip to Utah from this past summer there is a lot of wind rumble on the tape that interfieres with the voices and the general listening quality. How can I remove this from the audio? I have Sound Forge Studio 6e (now Screenblast Sound Forge). Can this do it or do I need to get the full Sound Forge 7?

Not much to do about this. And if you can do it, you'll probably remove parts of subjects voices too.
Maybe by working on a sampled section of this wind with Noise Reduction plugin to make a print then remove part of those sounds..? But as I said, you'll probably end up with cuts in what otherwise you'd like to keep.
You can also reduce a part of it with EQ but it's really not as easy as it seems.
If people in the film are "by the door", maybe you could embark on this magnificient adventure of doing post-synchro (voice overs) ie: re-record and synchronize in a studio those voices that are on the footage then add the "birds-crickets-traffic"sounds on different tracks so you can mix the overall after. Tedious though...

Voices are general converstion and really not much of an issue This was from southern Utah, Arches and Capital Reef areas and there is not much else there except the wind and rocks. I'll get the Noise Reduction plugin and give it a go. Thanks

Wind noise tends to create a lot of peaks. Use the clipped peak restoration set at default and it might help a touch but not much. And thats only if they are in clipping. Only other thing is to cut off your low end frequencies which you probably don't want to do.

Try the high-pass filter set at somewhere between 200 and 300 Hz, depending upon whether there is any dialog present or not. It won't kill all of it. Also the NR plugin for Cool Edit 2000 works well if you have it.

If the original audio isn't that important, replace it with a music soundtrack.

If it is true LF rumble, tapering off the frequencies below 90hz will help. There's not much you can do for wideband wind noise.

Thanks for all of your comments. I'll try a little if each to see what will work best for this project. And get back with waht worked best. Later.

Craftech: Try the high-pass filter set at somewhere between 200 and 300 Hz, depending upon whether there is any dialog present or not. The dialog is minimal to not existant so reducing but not totally removing is what I want to do and then add background music.

I looked for this high-pass filter in the audio plugins and could not find it. I don't have Noise Reduction 2.0 yet but I want to get it. Everyone is talking Hz (hertz) but everything in the plugins I have in Vegas 4.0d, seem to set db and not Hz. I'm not an audio person much yet but learning. What is the relationship of the two? How do I do this with the plugins I have in Vegas?

You can do this right in Vegas. Go into the track FX and select the Track EQ that is already added for you. The first point is already set for Low Shelf, which is what you want (i.e., low shelf is actually a high pass depending on whether you’re describing what you’re cutting out (lows) or letting through (highs)). Set the Frequency (Hz) to 300 and the Gain (dB) to –Inf (all the way to the left). Now listen to a loop of your audio and adjust the frequency to filter more or less of the wind.
