Hi Micheal,
My opinion here is that a sound recording could be very hard to prove as au=
thentic. Recordings might be great for supplementing your testimonials, how=
ever that alone will not give them scientific validity. If similar results =
can be reproduced by others following your documented method, only then wil=
l your approach become scientifically credible. A sound recording is merely=
 data, and data gets fudged all the time.
