Most humans can "hear" between 20 and 22k cycles; this range varies from
person to person of course, but it's highly regarded as "standard."  The
argument for higher sampling rates comes partly because of one theory
regarding auditory phenomena.  Some people believe that although we can't
audibly hear frequencies above 22k, we can "sense" them.  I wish I could go
further into this psychoacoustic theory, but that's about all I really know
about it.  If anyone else would like to share, I'd be interested in
knowing.

And hey... 24/96 is arguably indistinguishable from analogue, so I'm all
for it.  At the studio where I work, we're looking to upgrade the Sonic
Solutions system to 24/96.  It's just a matter of time before it becomes
standard.  Increased fidelity and 5.1 mix studios are soon going to be a
simple matter of course.

Just my 2 cents,
