Need to clean up this audio but not real familiar with what filters to use. Give it a crack and school me on cleaning up this audio. BTW, it's for a recruit video I'm doing. Almost forgot, I'm using vegas 5.

Here's an example of Adobe Audition's noise reduction plugin. I used two passes: the first to take care of the hiss, and the second to take some of those resulting watery stray-pitch noises out. It took under a minute. It's not the prettiest thing in the world but I think you can see how some tweaking could sound great.

Just realized you said you were using Vegas - sorry, I don't know the program! Audition is worth the investment, though . .

Abe, that sure did sound a lot better. That's exactly what I'm looking for. If I don't get any responses from vegas users then I may go with Auditions.

Lalo, Vegas does not include a noise reduction plugin. However, Sony does sell one of the best NR plugins available.

Other alternatives include the freeware/open source Audacity software, http://audacity.sourceforge.net/ which includes a basic NR plug. Many people seem to like Soundsoap for NR, I've not used it or Audition.

Thanks Seth, I'll give it a look.

Also try Goldwave. You can download a trial for free, and it's not expensive to buy. (Under $50 USD.) Here's the process:

* Open your clip in GoldWave. It supports 16 & 24 bit waves.

* Select a portion that has nothing but the noise that you want to remove. Copy it to the clipboard. (Ctrl-C)

* From the menu Effects > Filter > Noise Reduction. Select "Clipboard". I've been using 75% reduction with good results.

* Process the audio

* Save As

The UI is a bit primitive and not very attractive, but the above process is all you need for noise reduction.

Give it a try!

Thanks Jon, I have downloaded it and will give it a shot tonight.
