Default When did you switch to CDs, and why?

There were good all-digital recordings from the onset.
Does anybody remember Telarc?


I do, although I can't remember specific titles now.


You should certainly remember the recording of Holst's band music.

I can't believe that someone is actually saying this.


I made simultaneous recordings with the Nakamich version of the PCM-F1

harder and brighter-sounding), so they could not have both been perfect.


When I first started listening to CDs, I did notice that they sounded

harder
and brighter ... just like live music. It didn't seem like a defect to me.

Yes, but there are no native digital audio transducers. Air
has to move something. And assuming a conventional path with
A/D and D/A converters, the accuracy of converting to or
from numbers is what you're concerned with. It's getting
pretty good, and probably better than any analog transducer,
but it's not perfect.

and brighter ... just like live music. It didn't seem like a defect to me.


The first thing I noticed about CDs was that there was no
surface noise. While I don't let the occasional tick bother
me, none was really an ear opener. Since I don't know what
it sounded like in the control or mastering room, I really
can't say anything about the accuracy.

Some of the first classical music I ever bought in *any* format. A
Marine buddy got me started listening to it, reinforced by friends who
played it while we played role-playing games and while wargaming on the
sand table.

Telarc put out some damned fine material. My first was Tchaikovsky's
"1812 Overture," second was Beethoven's "Wellington's Victory." Yeah, I
was into the recorded firearms. ;^)

My gaming buddies got me into Wagner. That had me going to some Telarc
and a lot of Deutsche Grammophon, who put out some pretty danged good
digital conversions of analog recordings.

Yeah, I forgot about the Eric Kunzel one. I have that one, too.

Back then I wasn't all that into classical music, other than
experimenting with some of the stuff that was somewhat familiar to me
from movies and such, but it kind of grew on me. Then when I started on
the path to my music degree, I found that I was getting to truly enjoy it.

I'm still primarily a rock/blues listener, but I'll listen to just about
any genre at this point because of that experience. And I'm still a huge
Richard Wagner fan--enough to make him the subject of a few term papers.
Let me correct that--I'm a huge fan of his *music* but his personal life
was not one I'm interested in emulating. It looked, ummmmmmm... Painful.

Hard, perhaps, but not impossible. Since the accuracy of digital is

finite,
there will be some possible analog system that can fully exploit whatever
accuracy it provides. Beyond that, no improvement in the conversion is
possible.

A conversion can only be so good. There is an ideal conversion to digital,
beyond which the conversion cannot be improved. It's not like pure analog,
where you can tweak infinitely. For any given analog waveform, there is an
optimal conversion to digital. Once a converter achieves that optimal
conversion, no further improvement is possible.

The advantages of CDs were known long before there was any way to manufacture
them, And the advantages of digital recording in general have been understood
for a hundred years. It was just the engineering part that had to catch up.

It can indeed be perfect, because it need only match the resolution of the
digital domain.

For any waveform, no matter how complex, there is a single, optimal conversion
to a given implementation of the digital domain. Once you achieve that optimal
conversion, no further improvement in the conversion is necessary or possible.
And it is possible to achieve that optimal conversion in the real world. So
beyond a certain point, converters work perfectly, and nothing better will
ever be possible or needed.

me, none was really an ear opener. Since I don't know what
it sounded like in the control or mastering room, I really
can't say anything about the accuracy.


I recall my first experiences with CD, listening to a recording that had no
background noise. On a few early occasions I cranked up the volume on the
assumption that it was set too low, only to be blasted by the music when it
actually started. Unlike LPs, you could not guess at an appropriate volume
setting based on background noise, so sometimes you were surprised.

Probably not, but remember that by the time the CD came out, there had been
a century's worth of development in getting that bouncing rock to work right.
That's a very hard thing to do also. Electromechanical transducers always
are.

All things considered, digital stuff has come a long way since the eighties.
A lot of work has gone into making it sound good, probably even more than went
into the century's worth of record development.

Very true.

And I'd include in that the human factor. It took a while for some of us (many of
us?) to really get a full sense of what we had with the new digital medium.

Gone were the HF abberations of the LP that established a pleasant sense of faux
dimension; gone was tape hiss that gave us stocastic resonances that could
contribute various things (and mask others); and suddenly we lost the often useful
LF roll-off of tape (and many other sometimes useful distortions).

Not that tape and vinyl automatically give you a good recording, but by limiting
choices they did give a certain starting point.

with modern, higher-quality digital, you can't rely on the medium to help hide the
inherent flaws in the system (microphones and speakers and their locations in space,
primarily).

Whether you want it or not, with digital everything is there (or at least a lot
more). It's up to us to find new ways -- often developed over time in our
engineering subsconcious -- to define and maintain the illusion that is recording.

What is important to retain is that, in the digital realm, one cannot tweak
things forever. Once a conversion is optimal, no improvement is possible, and
no further tweaking makes any difference.

This is in sharp contrast to the analog world, where one can tweak and tweak
and always approach perfection a little more closely.

The irony is that analog systems can be perfect in theory, but never in
practice, whereas digital systems can never be perfect, even in theory, but
they often make it possible to approach perfection more closely than analog
systems do because analog portions of a system are vulnerable to physical
constraints, whereas digital components are not.

Seen from the digital side, that's true. Seen from the analog side, it's never
true (not even in theory).

A given waveform has one optimal digital representation, which is "perfect,"
because it cannot be improved upon in the digital realm. That representation
will never be perfect from an analog standpoint, because you cannot represent
an infinite number of points on a curve with a finite series of numbers.

What this boils down to is that, once you've developed an ADC that produces
the optimal digital representation of a waveform, any further development of
the ADC is a waste of time, because the digital representation can never get
better.

So if you have a $50 ADC that produces this optimal digital representation,
building a $5000 ADC accomplishes nothing.

Which in turn means that it's entirely possible that some modern ADCs are now
"perfect" from a digital standpoint, because they produce optimal digital
representations of their input waveforms. Which means that arguing further
about conversions serves no purpose--they are as good as they will ever be.

If you want to go further, you need a more detailed digital representation
(more samples with greater bit depth), and then you can build a fancier ADC to
create the necessary numbers.

I don't know if perfect ADCs for 16 bits and 44,100 Hz exist, but it's
certainly quite plausible to think that they do. In which case, there's
nothing more to be done for CD-quality sound.

square wave through the system without massive overshoot. Things are better
now.


So are they better, or perfect? Are there ADCs now that can produce an optimal
digitization of a majority of waveforms actually encountered in real-world
audio recording?

If not, then there's more work to be done on the analog side of the ADCs. If
so, then the only future improvement would be in increasing sample rates and
bit depths, and the current digital representations are as good as they will
ever get.

I consider it self-evident. A digital data stream is an approximation of the
waveform it represents. There will always be one--and only one--optimal
digital representation of that waveform. Once this representation is obtained,
nothing more can be improved.

That is the nature of digital systems, and it's one of the characteristics
that I notice that people with analog backgrouns have trouble with. My
background is digital, so I know the digital limitations very well, whereas
I'm much weaker with the ramifications of analog representations.

This is the hard question to answer, indeed.

But... the Weiss converters sound a little different than the Prism converters
which definitely sound different than the Grimm. So... if one of them is
indeed perfect, the question is which one.

You are looking at this from an extremely narrow point of view.

No, I'm looking at it from the point of view of someone who understands

and
has used digital systems all his life.


Most people in the audio and video worlds know analog, not digital, since
analog preceded digital and is still the most important part of any system
that interfaces with the physical world. But sometimes their

misunderstanding
of the digital domain can work against them.


All right... Explain the difference between digital and analog. I've asked
the members of this group to do this several times, and none has ever gotten
it correct.

Rut roh, Raggy.
Yes. Yes, you have.
Mxsmanic, you need to pack a lunch--we could be here a while.

I am not going to get into a discussion. I simply want to see whether or not
he understands. Nothing more.

Yes. Or perhaps none of them is yet able to do a perfect conversion. I don't
know.

I suppose you could examine the results by hand and calculate whether or not
the numbers coming out are indeed the best representation of the signal going
in. But is that really worth it?
