Jeff,
Thanks for the reply.
I am using separate noise profiles on each song, usually testing several regions, and trying auto, and comparing the B and C versions of Rx treatments. I always consider each recording as a new case to explore, and very rarely superimpose a solution coming from a different song. In the case of the near 20 hours of recordings, reduced to about 75 minutes, some songs were chosen by the musicians (all friends of mine), and the performances are really good. In this stage of pre-mastering, I'm just trying to reduce "a little" the sometimes over enthusiastic crowd's presence.
It's a stimulating challenge, and anything that I learn with this project will of course help in future projects.
Izotrope's Rx is a good soft (I also have Spark XL) and further processing in Neodynium helps as well. I have the originals in the session, and when mixing in the treated tracks, I do mute/solo comparisons to stay as close as possible to the original timbre and feeling, then bringing up the treated tracks to give a little more presence to the music. EQ alone doesn't allow this, but it's a tightrope as far as avoiding denaturing the overall sound.
As I said, this is not a pro project, although these musicians are top knotch.
Thanks again to all for youd advice!!!!

P.S. - I am thinking of getting a DSP card for my G5 2x2G OS10.4 that is compatible with PT7.4, and am leaning towards Waves APA, or TC Powercore. Any other ideas?
