[net.audio] CD's: The Power of the Producer

greg@olivej.UUCP (Greg Paley) (02/01/85)

Interesting as the discussions of sampling rates, D/A-convertors
and 14-bit(w/oversampling) vs. 16-bit technology might be, I can't
help but feel that the sonic effects induced by these factors are
few and subtle compared with what is happening in the recording
producer's hands during the master recording.

I have heard several good classical CD's, but, as of yet, none
that matched the extraordinary clarity and "presence", despite
surface noise, of the best analogue LP's.  This has included
extensive listening to Telarcs, English Decca's, Philips, DGG,
EMI - you name it.  I have, however, heard this kind of clarity
with the benefit of CD background silence on material that was
of less interest to me, specifically African tribal music (male
voice and percussion) on a Swedish BIS label CD, and the 
difficult-to-categorize sound effects on the Telarc "Time Warp"
CD.

Greg Rogers gets mad at people with no technical expertise who
theorize as to the underlying causes behind the audio phenomena
they perceive.  Unfortunately, the temptation is irresistable
to anyone who consistently hears certain things and cares enough
about it to want to delve further into it despite lack of experience.
In my case, the fact that the few CD's mentioned capture the
sound quality that they do indicates to me that the hardware itself
is capable of living up to its promise.  This brings us back, then,
to the question of microphone choice, arrangement of performing
forces for a recording session, and choice of a suitable recording
hall.

Recent players with recent CD's no longer display some of the most
obvious defects of the first products - lack of ambience, edgy and
metallic upper midrange, lack of depth and perspective.  However,
anyone with a good analogue LP playback system (I don't mean a
direct-drive table with a Shure cartridge) who is lucky enough to
have original pressings of the 1959 Mercury recording of Stravinsky's
"Firebird" (Dorati/London Symphony) or the 1956 RCA recording of
the same composer's "Song of the Nightingale" (Reiner/Chicago Symphony)
will know that there is still an intangible quality of realism that
evades the best classical CD's.  This quality evades even the best
Telarc recordings which, as I've been told, have painstakingly
attempted to replicate the miking setup used in the early stereo
Mercury "Living Presence" series.

My conclusion?  Not an original one: many of the basic ground rules
of analogue recording simply don't apply to digital recording.  Many
producers seem to have taken this to mean simply that a return to
the earlier analogue setup (fewer, more distanced mikes) is
sufficient.  I think that this is not enough and will still require
extensive and expensive experimentation before the potential of
the new medium is exploited.  I suspect that the worst problem, at
least as far as classical recordings are concerned, will be finding
that recording halls which were adequate for analogue recording 
will simply not work for digital recording or that, at very least,
the current techniques for modifying the sound of a hall (moveable
partitions and wall-hangings) will be proven obsolete.

I continue to experience that listening fatigue that others have
mentioned in conjunction with digital recordings, and CD's in
particular, on a variety of equipment.  In my own case, I've
been able to attribute this, on recordings that don't have the
obvious "early-digital" glare, to an exaggeration of the resonant
properties of the empty halls in which the recordings are taking
place, which was not apparent on analogue recordings made in the
same halls.

Obviously, I'm making guesses rather than speaking as one who
knows.  I'd be delighted to be knocked down by someone who has
direct knowledge of these things and who can point out where
my guesses might be erroneous.
