That's a different thing from a limiter. A limiter will keep the sound
from exceeding the clipping level, usually by making a "soft landing"
for the loud peaks. But, does not reset the overall gain.
What your are talking about is automatic volume control, or automatic
level control. This attempts, by adjusting the overall gain, to hold the
volume constant. By the very nature of the beast, even if working right,
it produces just the kind of up and down that you talk about. And should
be avoided completely.
