What is the essence of digital
recording/reproduction?
Digital recording systems work on the principal of turning a signal into
a series of binary numbers, which are then stored for reproduction. This
system of encoding averages the input signal to minimize the amount of
data generated. It was believed that 44,100 samples per second was a high
enough resolution to sufficiently encode any music signal without the
listener being able to detect the inevitable degradation.
Analogue encoding systems work by taking the musical information as it
is and turning it directly into mechanical movements ~as in the case of
vinyl or directly into magnetic modulations (as found on tape) which in
the replay stage do not have to be decoded or mathematically reconstructed.
There is no trickery involved; what you hear is what you had.
Reductionism
The scientific community has, over the past 10 years, slowly come to the
startling revelation, that there are many systems in nature that cannot
be broken down or reduced to a set of simple component parts. This realization
has overturned the prevailing paradigm of nature which as ruled for the
last 200 years. T he death of reductionism has direct implications for
the field of audio, and confirms what everybody has been feeling and saying
in private for some time about digital music systems; the resolution obtained
at 44.1khz is not high enough to reproduce music properly.
The resolution of analogue systems however, depends on the quality of the
materials and components used in the audio chain; in the case of vinyl, the
resolution goes down to the molecular level. It is millions of times more
sensitive than any digital system that has ever been manufactured.
Upgradability
Because digital systems
irretrievably reduce the input musical signal to a series of numbers that
is insufficient to encode all of the music, there is a limit to how much
you can upgrade your reproduction system (hi fi) to obtain a better sound.
No matter how much money you spend, the original musical signal can never
be retrieved belong the fidelity at which the encoding took place. With
analogue recording however, the amount which you can gain is enormous.
I he molecular resolution of analogue tape and vinyl facilitate this upward
mobility, and even if you don't choose to upgrade your equipment, the
quality of the signal is still preserved in your recordings, if you should
ever desire to take advantage of it. Digital denies you this potential.
What's happening in
the studios: engineers reactions
Studio engineers are consistently confirming that digital systems do not
measure up under close scrutiny. At a world famous audio mastering facility
which specializes in the preparation of lacquers and PQ encoded tapes
tot CD production, the verdict has been that digital must be treated with
extreme caution. At this facility, the production of masters is carried
out from many different sources; DAT, Sony PCM 701, analogue tape @ 15ips
and 30ips, 1630 U-Matic and Cassette. The Monitoring systems that this
studio employs are among the finest in the world, custom built and calibrated
by hand by an audio genius. Constant exposure to different kinds of music,
heard through an exceptional reproduction system, from different source
tapes, has given these engineers the experience to be able to judge audio.
Here is the testimony of one of their senior engineers. . .
"There appears to be an
unquestioning attitude to digital audio. It is generally and wrongly accepted
that digital recorders provide a true to original sound, however there
are many variables that can drastically alter the audio signal and there
is a widespread ignorance to the various permutations. On the simplest
level, one finds that comparable DAT players of different makes have markedly
different sounds. The variety of digital interfaces also gives rise to
further differences. The idea that a digital copy is an exact copy of
the original music is simply not correct. One can look at all of the variables
and reach a good compromise but manufacturers still have a long way to
go. There is also a growing feeling that the digital sound is conditioning
people to accepting the digital sound as the TRUE sound whereas in reality
digital systems impart a texture to the sound which is invariably 'restricted'
and 'stifled' as opposed to 'open' and 'breathing'. Sound engineers seem
to be subconsciously working around the problem, working towards a compromise
that 'sounds good on digital'."
The analogue infrastructure
The knowledge gained
in the manufacture and operation of analogue recording systems is invaluable
and irreplaceable. Research and development into further improving the
near perfect world of analogue audio reproduction has virtually stopped,
due to the destructive influence of digital. It is not only the patents
and designs that must be carried into the future, but also the personal
expert knowledge of engineers, gained over many years, which must survive;
knowledge which can never be replaced once lost - the knowledge of what
quality to expect from the best possible analogue reproduction system.
Analogue computing
Digital computing is
only an evolutionary step in the development of computers. There exists
today, the working components of a new type of analogue computer which
will revolutionize computing, and make digital computing obsolete. With
the establishment of analogue computing, all tasks that are now being
handled by digital computers will be switched to analogue computers, including
the recording and reproduction of music. Much experience has been gained
in the field of optical discs. High density optical discs will, without
doubt, be a major resource for data storage and retrieval when analogue
computers come on line. I he advantages of optical disc storage (when
the disadvantages of digital encoding are stripped away) are many; durability,
pitch stability, low distortion and track numbering to name a few. When
these advantages are combined with the perfection of analogue encoding,
we will have a system of playback and recording with a quality beyond
all expectations. Such a system however will be of no use to anyone if
the analogue infrastructure has been dismantled, and there is no one left
who knows first hand what real, true to life audio sounds like.
The mass destruction of
masters
For the moment, digital is here with us, and a terrible price is being
paid. l he entire history of recorded sound and music is being systematically
'saved' into digital formats . . . at 44.1 khz. This disaster is taking
place because of the life span of recording tape; the glues that have
been used to bind the magnetic material to the flexible substrate of most
recording tape have been found to be decomposing, putting at risk most
of the master tapes that have been recorded in the last 50 years. In what
seemed like a sensible move, all of these master tapes have been scheduled
for saving to digital; (also, conveniently, this ties in with the re-releasing
of the back catalogues of most record companies onto CD) I. What nobody
bothered to tell these companies, is that digital sounds like shit; and
so, thinking that they have permanently saved their masters, the record
companies are THROWING AWAY their original analogue master tapes. . .
to save space. When the penny drops it w ill be too late. All of~our favorite
music will be lost forever in a quanitized quagmire of brittle, cold,
shitty sound, and for no good reason, because analogue machines could
just as easily be used to preserve decomposing masters.
The proper place for CD
CDs are very useful,
just as cassettes are useful; they have a place in the audio chain, and
should be used and sold; BUT NOT TO THE EXCLUSION OF ANY OTHER FORMAT,
and certainly not to the exclusion of vinyl, which is the best mass produced
reproduction carrier ever made.
Who's in control?
You have to wonder how this sham has continued for so long, and of course,
we all know who is behind this insane state of affairs. The audio equipment
manufacturers have realized that if they design and manufacture the hardware
i.e. CD players, mini-disc, l)CC, they must control the manufacture of
the software I music) to ensure that their investment in time and R&D
pays off. Sony learned this the hard way, with the failure of Betamax;
it failed because there was no software available to watch; they tried
to push the system, licensing movies from film companies at huge cost,
but it was too late. NOW Sony owns Columbia Pictures, and every picture
they have ever made, so if they want to launch any type of new hardware
to play movies, the availability of software will be no problem, no matter
how good or bad the system is; they can even release films on reels of
spaghetti if they want to. Sony also own CBS records and the CBS back
catalogue. Phillips own Phonogram and A&M. This is a terrible situation,
not only because the production of music is in the hands of a small number
of giant companies that are also the exclusive manufacturers of all audio
equipment, but because these companies are deaf to sound quality, due
to their need to launch more and more new playback formats. Mixed with
the profits to be made from re releasing hijacked back catalogues, the
resulting brew is poisonous; companies that profit from reissuing old
music again and again into a never ending stream of different and inferior
devices to a public addicted to electronic novelty. GOD SAVE US ALL.
It's not too late
Most of the engineers and companies involved in the production of analogue
recording systems still exist and are working. If we stop the digital disease
now, music and sound in all of its intricacy will be saved for everyone. Keep
buying turntables and vinyl records. Keep buying cassettes. Boycott any release
that is on CD only for no good reason. Make sure that the labels you buy from
are not controlled by the manufacturers of music systems. It is the only way
we are going to save sound.
