Well, the first problem would be that each musical instrument has
its own point(s) where its sound vibrations originate...and our
ideal "reproducer" would have to duplicate that/those characteristic(s)
exactly (and, to complicate things, all of the echoes, reflections
and cancellations of the venue in which the instruments were played!).
As well, since the "reference ideal" would assume that the two ears
of the listener were in a given pair of locations...this ultra-
recording would only be accurate if the listener was located in
that exact same spot!
Finally, because of the ever-present possibility that age, infirmity
or other agencies had left the listener with imperfect hearing...in
order to obtain fully perfect results, the sound would have to somehow
be transmitted to the otic nerves in nerve-recognizable electric
But, once we solve those little problems, we should be able to
transmit related data to the other sensory systems, so the
"experiencer" (the term which will have to replace "listener")
can actually revisit the space/time/location continuum in
which the event was recorded...
