What's left for debate is whether the sampling frequency used for

is already at or beyond the limits of human hearing

It is - when digital was in its infancy I and many of my colleagues
had an
opportunity to play with different sampling rates on a wide variety
of
material. And the point where any difference is detectable is below
that
of CD - *that's* why it was chosen - although the exact rate was
down to
TV video parameters so video recorders could be used.

Wasn't there another reason for choosing this particular sampling
rate - it
allowed storage of approx 1 hour of music on the CD technology
available at
the time?

IIRC it was to get the whole of Beethoven's 9th symphony on a single
disc or is this an urban myth?
