[net.audio] Why you might want pitch-control

greg@olivej.UUCP (Greg Paley) (09/20/84)

A recent posting which mentioned a CD player with a
variable pitch control will probably provoke several
"why do you need one?" responses.

There is, of course, the obvious situation of musicians
who like to "play along" with a recording and need to
adjust for the differences in tuning of different orchestras
(such as the notoriously high tuning used by the Vienna
Philharmonic both live and on records).

There is another reason that many people may not be
aware of, which is of interest to anyone who collects
transfers of "historic" material originally recorded 
on 78's.  Many companies who have issued LP transfers of
78's have been careless in matching the actual speed
of the original recording (which has been known to vary
from approx. 65 RPM to 86 RPM).  RCA Victor, with one 
of the most extensive catalogues of "historic" 78's
(Caruso, Flagstad, Toscanini, among countless others)
has been particularly bad about this.  There is a record
of arias by Rosa Ponselle which contains a "Willow Song"
from Otello, dubbed a full half-tone sharp, thus rendering
the voice unrecognizeable from the rest of the selections.

So far, this has not applied to CD since, to my knowledge,
there are no CD's yet available of material originally
recorded on 78's.  The presence of "digitally remastered"
Toscanini performances on the RCA Gold Seal label indicates
that CD's of the same material may be on the way (although
so far, the selections chosen were mastered on magnetic
tape).  If this happens, the reccurence of this pitch
problem will depend upon whether the digital "master" is
remade from the original shellacs, or is taken from the
same working tape which was used for the previous LP
transfer.
