Noise reduction for sequences?

Hi.
I'm working on a short film project and I edit in Premiere CS6. Now there's this noise from a fan in all of the clips and I want to get rid of it and I know how to do it with a single clip in Audition, but that would take forever to do with the whole sequence. And I don't want to use Adaptive noise reduction where you can't capture noise prints. So is there a faster way to use noise reduction for a whole sequence in Audition? Maybe add noise reduction in the multitrack or something? Please help me!

Sorry, there isn't.

The normal process here is to treat all dodgy audio before you mix it - this gets over level shifting issues, and is generally a much more satisfactory way of proceeding. Noise Reduction is a process effect, and it can only be applied to one file at a time - you can't use it in multitrack.

Damn it. Well, that sucks... I guess I have some work to do then.
Thanks for your answer though, it was very helpful.

You haven't said which version you are using, but:


Just to make you take even more time though...

..,Instead of using/saving one NR setting and try to clean up your signal in a single pass, you can almost always get better, more transparent results by using three or four passes with the Noise Reduction and dB Reduction sliders set to fairly low values.  Increase the FFT size (on the Advanced menu in Noise Reduction) and increase this setting for each pass.  You'll find that working this way you can kill even pretty severe noise without the swishing, robotic character you can get with a single, extreme, pass.
