True, but one method to help protect your eardrums if there is a strong
signal on frequency, and while the AGC is catching up after being reset, is
to slice / clip the audio at a level above the normal listening level peaks
but safely below the "blast threshold". Not a pretty solution but at least
it is not too complicated.
