Audio enhancement

All modern ham rigs incorporate compression in the audio chain; this effective
pushes up the room sound a bit without the echo/reverb being overpowering.

It is puzzling why hams have not commonly adapted well-known psychoacoustic
observables to increase intelligibility. These include: a 50 ms delay on
transmit; and binaural (delay and phase invert) synthesis on received. The
latter has had some exposure in recent years.

I recall using both the of these circa 1985 at Field Day with pro audio
outboard boxes. The problem--on transmit--is isolating them from the RF so they
don't overload.

CB has always had an over the top approach to audio--which rather defeats the
purpose of said synthesis.

Anyway, old stuff, well-known to music producers and some audio engineers.
