Post prod. sound Issue
We filmed a scene in a coffee shop, and kept background noise static for the shoot. But, when we got into post prod. we noticed there are a couple cuts where there is air conditioner noise that we didn’t catch, making the sound uneven on those cuts. We are using Premeire Pro (and have access to Sound Forge) is there anything we can do to eliminate the noise or even dull it down, without affecting talent audio?

Sony sells a noise reduction plugin that works with soundforge and Vegas. Or if you have the production suite a similar tool is part of Audition.
Basically you find a section of audio that has only the background noise and sample it. The plugin then attempts to remove only the frequencies it had sampled as “noise”.
It usually works pretty well with things like air conditioners. But apply it sparingly or your audio gets an aliased “processed” sound to it.
Another technique is to use one or several “notch” filters. These allow you to boost or cut a very narrow frequency range. Often used to remove 60Hz “hum”. -
Also try Adobe Soundbooth. It has some great noise reduction tools, and you can still download the beta software from Adobe.
