I don't recall the technical explanation...but DO recall that it
was regularly held by sound fanciers that "the faster the record
turned, the better the fidelity was!"
Actually, the ideal format (which Edison knew) for sound recordings
is the cylinder...which maintains the velocity of the playing stylus
(unlike ordinary disc recordings) for the full extent of the recording.
And, a "properly made CD" gives perfect reproduction...of an
IMperfect (though not audibly so) version of the original
recorded sound! Given the improvements in data storage and
data handling, we should see LESS imperfect (though not
technically perfect!) sound recordings...
