Help with Sound Forge w/Noise Reduction 2.0 -Sound Forge - PC

Subject:Help with Sound Forge w/Noise Reduction 2.0 Posted by: wtdedula1 Date:4/18/2003 9:05:28 AM Hello All; I shot a wedding video for a friend in Hawaii right near the ocean and I experienced low audio and a lots of wind/surf noise (Shhhhh). I purchased Sound Forge w/Noise Reduction specifically to minimize this noise and increase the level of the voice but I am not having much success, Can anyobn e offer any tips on how to remove specifically this type of constant wind/surf noise in the background without reducing the voice too much .. in Sound Forge and/or Noise Reduction ? Are there any tools better than SF/NR for specifically removing this type of noise ? I can send someone a 2 MB source clip clip to illustrate what I am trying to work with if you'd be up to the challenge of demonstrating how the noise could be partially removed, and the voice enhanced. Thanks for any help/suggestions you could provide. Tim

To put it simply, sometimes you cannot fix bad sound. It sounds like the wind and the surf make up a large protion of the actual sound. I use noise reduction, and sometimes I simply have to dubb the sound in again. Noise reduction is mainly for hiss, pops, clicks, etc. What you are asking for, to me sounds like you want to reduce what is actually the major portion of the sound bite. Thats like saying, how to you get rid of the voice and keep the wind and surf. SF & NR are top quality, but you are asking for something that I would have trouble correcting on equipent and software worth 30 times more than SF. That said, use noise gate to get rid of any sound in between gaps in the words, then use noise reduction to get rid of as much of the crap you do not want, and then use some dynamics to boost the voice left over, maybe add some bass for depth, etc. A conversion on to DVD, VCD, or video will also knock some of the high pitch stuff down as well.

If volume is really low, this can be difficult, but I find a combination of EQ and NR a good fit. The problem will be that the swish and rumble of the ocean match the frequencies of the voices you want to preserve. Not much you can do about that, unfortunately, except to overdub.

Highlight a half-second of it and select Noise Reduction. With that type of noise, it is probably best to use mode 3. In order to preserve voice integrity, do not exceed 20 per noise reduciton pass. Then when you have reduced the noise, perform the Wave Hammer function at the voice setting. If the volume is too low, experiment with the Normalize function. God Bless, Shahn
