By this weekend, I need to be able to explain what sound I am hearing
to someone who isn't a broadcaster or associated with radio / audio in
any way. How can I explain to someone what it sounds like when you
are speaking into a mic -- hooked up to an audio board - and you pin
the needle in the red. You know, you get that high pitched kind of
flat sound ?? I don't know how to explain it to someone who has never
heard what that sounds like?? Can someone suggest an explanation that
would make sennse to non-radio people?? Thanks.
Look up audio clipping, square waves, voice coil failure modes due to
clipped waveform; and like that.

Maybe what I'm really looking for it the piece of equiptment that has
that red needle. It's been awhile since I had to do the vocabulary of
all this. The little needle that bops into the red area - what piece
of equiptment is that?? I looked up audio clipping and that's a
pretty good explanation but it still doesn't exactly say what it
sounds like. Thanks.
It sounds like the speakers are ripping themselves apart, which happens
faster when you clip.
