I just listened to a Balthazar dialog, and I think the one effect I have not mentioned yet is the pitch shifter. The audio track has a pitch-shifted, octave down component mixed in with the normal voice. I believe that, along with a good mic of course, is what gives you the low grumbly tone. A vocoder could do something similar (a la Mr. Roboto), but I am pretty sure we are hearing a pitch shifter in this case.
Oh for God’s sake. Of course it is! Feel kinda stupid for not thinking of that.
Just tried with Gale and made him sound a lot more sinister talking about Mystra. Think there’s probably a bit more going on, with reverb and possibly some modulation, but that seems to be the key thing.
I bow to your superior sound design knowledge.
So ignore what I said before.
(Except about buying a mic, I stand by that)
