I have the Universal Audio Ocean Way
plugin, which includes a mic modeler. I briefly tinkered with it, but haven't used it yet. It made very noticeable changes to
the tracks I tried it on, and generally sounded pretty good.
But I have to say, I don't really get it - I mean, my tracks were actually made with a particular real live microphone, which has its own sonic/electro-
acoustic properties and sends X amount of analog information to
the preamp/converter, which then goes into the computer where it sits. It escapes me how the mic modeler could add any information to what's already there - it could certainly transform and/or remove bits of information, but I fail to see how this gets you to a track that is really similar to one recorded with one of the modeled mics. That said, I don't have experience with most of the mics that were modeled, and so I'm speculating. Anyway - cool effect if nothing else.
I think I do have at least one of the modeled mics (same make/model, that is, not the self-same microphone, of course) - if I get a lot of time on my hands, maybe I could experiment a little - have
a reference track using the modeled mic, and some other tracks with other mics to which I would apply the model and see what happens.
I got a chance to try out the line 6 wireless modeler and thought to myself that I can get close to those settings with critical EQing and processing.
Yeah - when you think about it, you have to wonder how much of these plugins are really just different user interfaces over the same transformation
logic. Not that that's bad - the UI can make a big difference - it's just kind of interesting.
