Alan,

As Mac suggests - post a snippet.

Can you isolate the noise to a particular track in your mix? Guitar amps/tracks are notorious. So are mic channels with improper gain staging.

Let's assume that it is a track or two. Have you tried a noise gate plugin on those tracks? If not, do you know how noise gates work? If not, here's a decent article on it in Wikipedia: http://en.wikipedia.org/wiki/Noise_gate

Pay attention to the first section primarily as well as the figure to the right of the first section.

I can't recall whether PG products have a noise gate process or not. I think they do. Should you need one, here's a really simple little one from Graham Yeadon which does the trick for me. http://www.gvst.co.uk/ggate_manual.htm

That link is to the on-line manual. The only difference between Graham's 3 controls and that in the Wikipedia article is that Graham's 'Fade' control is analogous to the Wikipedia 'Hysteresis' parameter description.

If you can isolate it to a track or two, in a mix with several tracks, taking care of the noise on a track by track basis is always the preferred way to go than trying to apply some kind of noise reduction process across a 2 track mixdown.

Go back to the tracks, jack! As Mac points out, if you can re-record after finding the source of your noise, that's an even better way to go.
