As I said earlier, these days manufacturers take even less care with
vinyl than they do with other media sources.
CD technology could and should have given us a flat FR from near DC up
to 25kHz, easily covering the range of human hearing.
**Bull****. With a sampling rate of 44.1kHz, Nyquist tells us that the
theoretical maximum of CDs is 22.05kz.
As it was actually implemented it was something of a compromise,
sacrificing FR to give greater playing time, but the space available
on the prototype technology "COULD AND SHOULD" (note what I actually
wrote) have been allocated differently to give us a shorter playback
time at a higher sampling rate that would have covered the range of
human hearing.
Even going up
to 22kHz it still covers quite comfortably the range of older
listeners such as myself.
**It actually covers pretty much everyone over the age of 10.
I and several others tested the range of our hearing in the Physics
Lab at college when I was about 17 or 18, and I wasn't the only one in
the group who could hear above 23KHz at that age.
So to all intents and purposes we could and
should be getting near perfect audio reproduction. But what do we
actually get? While there are some very good quality CDs available,
even of those recordings originally released on vinyl, there are also
too many examples where the sound has been ruined by over-processing.
As has been said many times before, the fault lies not in the
technology, but in the people who use it
**Duh.
Duh indeed!
