Limiting is a form of compression since it removes excursions in excess
of
the level that would produce 100% modulation (or 100% negative peaks on
AM).

Not really. Limiting is a hard stop that is not ever passed. Compression
is an algorithm applied to the program material that attempts to prevent
reaching that max limit but it could go over limit in extreme
circumstances.

That's the definition that fit 30 years ago. Today, audio processers like
the Optimod and the Omnia employ delay to look ahead at the audio, then,
with advance knowledge, know when to reduce gain to prevent the need to peak
limit by hard clipping. So what we have is a merging of the concept of
compression and peak limiting. It's all achieved by looking ahead to know
how to process the audio that then heads to the transmitter.

It's what works.

I don't think so. Maybe that's why I can't listen to most FM stations as
you helped pervert the sound.

There are about 30,000 stations in the Western Hemisphere. I can't see how
one person's adjustments can influence all of them.

The real truth is that stations have realized that a sound that is loud,
level and specttrally balanced wins if the programming is right.

Today's radio sounds infinitely better than it did 30 or 40 years ago.
