Like I said, it may be the piano that doesn't really produce much of a
ping on the highest notes.  But all of us have some hearing loss as we
get older.  The point is that you can't judge how others hear based on
what we can hear.

I never said that *anyone* can hear sounds above 20 kHz.  I said that
there are people who can hear the difference between systems that use
higher sample rates than 48 kHz.  The real issue is about the
electronics and how they are measured *compared* to human hearing.
Distortion is the real issue.  Filters introduce distortion and some
people can hear the distortion produced by converters running at 48
kHz.

I suppose it is possible that my friend was mislead (and therefor
myself).  I have no first hand knowledge of the sound tests.  But he
is not a person to believe in rubbish.  In fact, he is a person who is
very intellectually critical.  This is one of the few times he could
not dismiss claims that run counter to the science.

Oh, about the Robert Wadlow's of the acoustic world... if lumber in 10
foot lengths were the same price as 8 foot lengths, why *not* build
homes with 10 foot ceilings?  At one time 9 foot ceilings were the
norm.  What is the delta in price, power or anything else going from
48 kHz to 196 kHz sample rates???  My present design is using a CODEC
capable of 192 kHz sample rate even though I am running it at 8 kHz.
It is actually a bit cheaper than a similar chip from the same maker
that only runs at 96 kHz.  The power consumption is only a few mW
higher and I have no idea of what the OP meant by the waste of
"time"...
