What I hear is dynamic, not just a low shelf filter. I looked up apulSoft
apQalizr, and it appears to be a very nice equalizer with analyzer plug-in, but
no dynamic action. Hitting a limiter would have the opposite effect, reducing
noise during the vocalization, so I still wonder what you did that resulted in
the expansion effect.
