I've imported a clip from Premiere Pro CS5 into Soundbooth. Found a spot about 1.25 seconds wide where the only audio is room ambient -- background junk like the HVAC sounds, lights buzzing, etc. Used the "Processes...Capture Noise Print" function in Soundbooth to snapshot that noise and use it as the basis for the Reduce Noise filter. The end result is outstanding! Works like a charm.

Now all I've got to do is apply this to the next 12 clips in the Premiere Pro timeline (the project is various clips taken from video of a 3 hour long cooking demonstration). All the clips share the same sound setup, and the same ambient noise profile, so I need to use the same noise print (and the same noise reduction settings of course) to make the entire timeline sound "seamless" as it were. And I can't find a way to store this noise print to a file so I can call it up and use it for the next clip.

How does one apply the same noise print to a set of clips?

I have my system in a state of disassembly at the moment, and I can't remember if you can select a series of clips and get them to edit in soundbooth as a group in one project or not...

I think in CS4 I used to leave the soundbooth project open and the second (et al...) audio clip would load into the same soundbooth project as I sent them from the PPro timeline...

You might give that a try. After you've captured the initial noise print, you could then apply the same process to each clip without losing the sample, or having to recapture a new profile for each...

If that doesn't work, I'm sure there's a way, but I'm much smarter when I can actually test-run an idea here before I give it to somebody else.

caveat emptor I guess....

I've never tried to batch process in SB as you are describing, so I don't know if it can be done.
However, another approach, if the edit is finished, is to render the timeline audio to a single file, then apply the denoise filter to the new file, save, import to PPro, synch it to the project timeline, and mute the original audio clips.

Yes. That might just be the ticket. I'll have to give that a try.
