I know a software solution has not been solicited, but I recommend trying a free plugin by
Flux, and it is called "Bitter Sweet." It is a transient designer. Learning it takes an
ear and a little experimentation, but it could be just the thing for you.
It
makes a couple of rather grainy LD mic's I have quite tolerable that otherwise wouldn't
be. It can work well for ratty mic's and, well, less than optimal choirs. It smooths
without compressing. (It can also go the other direction, too, increasing transients.)
Also, there is an unusual equalizer that permits quite delicate shaping or
reshaping of a microphone. It, too, is a free plugin called "niveau" by Elysia. It is
distantly related to a tilt box, and the *slightest* adjustments made at the right
points-which are often counterintuitive-can make something useable that might not
otherwise be.
Both plugins, though free, are of very high quality.
Try the transient designer first. As you might imagine, these plugins work very
differently, have different effects, but one or both might be useful for you. And you
wouldn't have to get another mic-for awhile.
Yet another suggestion for mouth noises-try a declicker. For grosser mouth noises,
there's always RX2.
To answer the question you posed:
Try the
Milab DC-196. Very nice. Not cheap. Not expensive.
