Depending on the artist, venue, purpose (was I specifically asked to do something vs. taping for personal use), my mood, etc., I will use some, all, or none of the following post edits (typically in this order of workflow, and ALWAYS saving an original in addition to the mastered files):
1. Fix any clipping that might have happened with Sony Clipped Peak Restoration & Waves X-Crackle VST
(that combo can salvage the unsalvagable sometimes)
2. Unwind/reverse/level-off any riding of the levels I might have done at the start with volume envelopes
(i.e., started too hot, so dialed levels down, in post, I'll bring the opening down to the levels I eventually stabilized on)
3. Adjust left and right channel level if one was run a little lower/hotter than the other
(this is NOT panning, which may blend the channels depending on s/w and setting, I just add a slight bump to one channel all by itself)
4. EQ if needed (typically rolling off some bass, but sometimes brightening up the mids, but not too much EQ if any usually)
5. I might use Waves S1 Stereo Imager to expand soundstage or rotate it a tiny bit if my seperation sucked or I was asymetrically positioned
6. I might add a tiny bit of Waves R3 reverb if it sounds flat/dry (usually only do this with small classical ensembles in a dead room)
7. Always normalize if I can get anything out of that
8. Might possibly compress a tiny bit using the Waves L3 MultiMaximizer (never that much, but sometimes use this instead of normalizing by going just a bit farther than I could have with a straight normalize, I basically flatten out some of the big peaks without doing much more)
9. This is the point I'd mix AUD/SBD parts together if doing a matrix in post (I'd have mastered each seperately first, then mixed)
10. Then of course, I track it, and depending on gig, maybe fades in/outs on tracks or only at beginning of 1st song and end of last
But like I said above, I might not do ANYTHING just as easily as I might mess with it all -- but the key is not to do too much of any one thing, just a tiny bit here and there, otherewise, you'll end up ruining it more times than not. It just depends on a bunch of factors...
