Room noise

[Andre Gagnon]

You need Audition to do that. Have a look at this Tutorial on the COW:

Although two random white-noise sources will average toward zero when you add them, I doubt that adding two sound tracks has a useful result. Put the room sample on a separate track and play with the gain to see if you can hear an improvement.

It’s probably more beneficial to play with the filters in Audio Effects. I find the notch filter great for removing air conditioner hum in auditoriums, for instance. Bandpass is useful for quiet times, but usually detracts seriously from content if you use it when there is any.

Noise reduction works great in audition if you have a sample of room tone. Just curious, in most situations it actually works better to just “lay down” room tone under a whole scene so that room tone doesn’t change with each cut.
