Gary, I bought your software, and this is the thanks I get? :)

Beyond the fact that the shoot is already in the can, it was shot in a stadium about a half mile from I-95. Windows, unfortunately, were not an option.

Unfortunately, I think you'll find that unless the noise is a constant frequeny throughout you won't be able to remove it (without a lot of unwanted artifacts anyway).

That's the thing. It's so distant that it's almost like white noise. But not quite.

There are so many settings in the noise reduction plugin that I'm hoping that I'm just not using it right. And that one of the audio gods in here will show me the error of my ways. :)

The noise reduction plugin is not likely to be of any use. It really doesn't help much with white noise when both the noise and the main audio don't vary much in intensity.

For situations like this, sometimes the best thing is to add sound. Add music or narration, for instance, and it will mask the sound.

I have also had good luck by adding sound from another microphone: If you recorded the event with more than one camera, you can sometimes add (or even subtract) the two sound tracks.

If you have a quiet section that has just the noise, put that into the Noise Reduction Plugin's spectrum analyzer. You might find one or two frequencies that are prevalent. You can sometimes help things by using the notch filter to reduce just these frequencies.

One general tip about Noise Reduction is that it is sometimes better to remove noise in several small steps rather than one big. Don't ask me why, but I've heard it work.
Another thing you can try is a combination of NR and noise gate. Experiment with the attack rate to get the smoothest result. THEN you may be successful at adding some extra noise (controlled amibience, music, whatever) to camouflage the highway noise (what's left of it) and the silent gaps you've created. Finally - in addition to filtering out the dominant frequencies of the noise, you may try to increase the level of the dominant frequencies of the sound you WANT to hear.

Try using the equalizer and muting different frequencies. I have had marginal help from this before also.

By the way, was stadium you are refering to the Ravens? It would be great to know there is a fellow Marylander (or someone close) using vegas. I sometimes feel like I'm all alone in the nation's capital. Sorry to wine, just lonely while everybody else is taking their Sunday nap :)

Close. Ripken Stadium in Aberdeen.

You're not alone. I live in Capitol Hill. You?

>>"That's the thing. It's so distant that it's almost like white noise. But not quite."<<
That being the case I would think you could eliminate a lot of it with several smaller passes (say -8 db) as Tor suggested.
Randy

Excuse the possibly ignorant question, but how do you do that? By chaining together several NR filters?

If you had soundforge you could try using the compressor and set a higher noise floor. If you like send me a sample of your sound. whats your email addess ?

cheers

I live in Owings Mills, but attend school in Baltimore. We need to convince spot to bring vasst out here or something. Bye the way, nice web site.
later,

Try Audacity or Cool Edit 2000.

My recommendation would be to use the noise gate with very fast attack and release times.

I'm with craftech. Try Cool Edit. I had some video taken outdoors and half way though a jet went over. I did 3 or 4 passes with Cool Edit's noise reduction feature, each time picking out what was left of the jet noise. It turned out pretty good. Then I did one more pass and elevated the overall sound level. And, the good thing about it is that you can preview the changes before you render the sound file.
