AUTHENTICITY: Electronic and physical microscopic examination
of a tape to prove that it has not been tampered with, altered,
or otherwise changed from its original state. Another common
authenticity challenge is to determine whether a given was tape
was indeed made on a given machine.

frequency and amplitude characteristics of a human voice and
compare it against known samples.
