Default Volume and dynamic range question.

Hi all. Here's a question that came to my mind recently while listening to my
stereo. Let's say i set the volume knob to #3 for example. What loudness of
the music does this represent? It seemed to be set to a particular level, but
when a dynamic peak of the music came along, the volume increased accordingly.
So, what does a #3 setting mean? Is this the maximum volume level the music
will play at? If so, why do short term dynamic peaks sound louder? -Bob
Bernstein.

Default Volume and dynamic range question.

Thanks Kal... i THINK i "get the concept". If i understand correctly, each
numbered volume setting corresponds to a range of loudness depending upon the
dynamic range of the signal from the recording, right? So, if my preamp is set
to #3 is there any way to determine in db the corresponding volume range this
setting will produce given a particular signal? In other words, can we say
that setting #3 corresponds to a range between 10db minimum to 30db maximum
depending upon the dynamic range of the signal? And that setting #4 corresponds
to a range between 20db minimum to 40db and #5 even more, etc? And, is this
range always the same for every amp combination (ie. a fixed value), or, does
the range differ between different pre-amps? -Bob Bernstein.

The answer is that each setting determines a particular gain and it
can usually be defined by a single number, e.g., +22dB. That means
that all input is increased by 22dB and comes out 22dB louder.

As for the number for your amp/preamp, you would have to measure it
unless it was calibrated in some way. There are no specific
standards, so each amp/preamp is somewhat different.

the dynamic range is set by the initial recording (the CD) it is the
same at level#3 on your preamp as it is on level 4 as it is on level
10. just the volume level at an individual point in time on the
recording changes when you turn up the volume. eg when you turn it up
from 3 to 4 the volume increases by say 10dB, then the loud peak
increases by 10dB and the quiet passage increases by 10dB and,
importantly, the noisefloor increases by 10dB. The dynamic range
possible on a CD is about 96dB ( some manufacturers say its more) this
seems good until you realise that a lot of classical and jazz
recordings have long passages at 40dB or more below the peak level.
When you turn it up so that these parts are nice and clear the noise
floor becomes audible(and CD noise floor is a lot more ugly than a
vinyl or cassette). This is why new formats such as DVDA and SACD have
a much larger possible dynamic range.
Thats the theory anyway. In actuality hifi equipment usually doesn't
allow the full dynamic range through especially on percussive sounds.
This is called compression and as you turn the volume up on your
preamp the sound is compressed more. Better hifi equipment (not
necessarily more expensive)compresses the sound less.

Pardon me for jumping in with a tangential topic, but the noise floor of a
*properly dithered* CD should *not* be any more "ugly" than that of vinyl or
cassette. In fact, it should be much lower (number one) and it should be
much more consistent (number two). Even the best vinyl, excruciatingly well
maintained and cared for, has clicks and pops which I consider to be
extremely ugly and very distracting. The noise (distortion) increases
dramatically during loud passages. Cassette noise (especially with noise
reduction, even Dolby S, which is quite good) is modulated by the signal.
Furthermore, any frequency response and gain errors are magnified by the
expander circuitry.

If I'm going to be listening to an extended passage recorded at -40, I'd
much rather it be on a CD than on vinyl or cassette. The CD noise floor will
still be 50dB below the signal, compared to -20 or -30 with the best vinyl
or cassette. My hearing isn't what it used to be, but I'd be hard pressed to
hear a -90dB noise floor with my amplifier gain set to any sane playback
level -- Unless the CD noise floor was highly correlated noise, like a tone
or something (which I have *never* heard even on my worst CDs). Again, if
it's properly dithered, the noise floor should be completely uncorrelated.

As for whether SACD is really better than the CD format, there is another
thread on this newsgroup which points out a problem with the SACD standard
which makes it *impossible* to properly dither SACD audio. It appears the
creators might be fixing this problem, but only after it was pointed out to
them by a couple of the best engineers in the digital audio field. We may
have dodged a bullet there...

Ok your points are valid if you want to get technical. I was simply
trying to explain the limitations of the format without getting too
far into it. However the noisefloor on a cd is more ugly than
vinyl/cassette/analog tape, that is why we cover it with dither.
Dither is simply noise similar to cassette noise that is ADDED to the
audio signal it is not the noise floor of the cd.
As far as SACD (and I really think we are getting away from the spirit
of the initial post) people are way too worried about the
technicalities of the format. The noise floor of most microphones is
higher than that of sacd so it will be sort of dithered anyway. Also a
lot of people who are mastering for sacd use 192/24 equipment to edit,
dither, normalise etc and then make the final dsd conversion last
thing. This may seem like an impure path but at that resolution it is
fine. 192khz is deliberatly over-spec'd to allow for a bit of give and
take unlike cds which are a bare minimum spec.

Given that the amp does not clip, and has a noise floor lower than the
CD player, this is certainly true.

The dynamic range
possible on a CD is about 96dB ( some manufacturers say its more)


No, the theoretical maximum is 93dB, regardless of what any
'manufacturer' may claim. OTOH, no one has ever been able to
demonstrate the existence of a master tape with more than 85dB dynamic
range, so this is hardly a problem!

this
seems good until you realise that a lot of classical and jazz
recordings have long passages at 40dB or more below the peak level.
When you turn it up so that these parts are nice and clear the noise
floor becomes audible(and CD noise floor is a lot more ugly than a
vinyl or cassette).


An old urban myth, but on any properly dithered CD (which is why it's
93, not 96dB), the noise floor is absolutely smooth - unlike that of
vinyl and cassette! It's also at least 20dB lower than is possible
with vinyl or cassette.

This is why new formats such as DVDA and SACD have
a much larger possible dynamic range.


As noted above, any more than 85dB is simply unnecessary, as there are
no master tapes which exceed this.

Thats the theory anyway. In actuality hifi equipment usually doesn't
allow the full dynamic range through especially on percussive sounds.
This is called compression and as you turn the volume up on your
preamp the sound is compressed more. Better hifi equipment (not
necessarily more expensive)compresses the sound less.


On any halfway decent gear, this applies *only* to the speakers. There
should be absolutely no compression occurring up to the speaker
terminals. It can be a serious problem with conventional box speakers,
but some makers such as Dynaudio and ATC go to great trouble to
minimise this effect.

As best I can determine, Sony's engineer's had already built eight-bit
processing into their workstations to deal with just this problem well
before "it was pointed out". Obviously since Sony's marketing people were
stressing "single-bit DSD" processing they didn't go out of their way to
publicize it.

But that doesnt' change the fact that DSD processing through the
record/decode cycle offers more natural sound than either cd or dvd-a. I
look forward to the day we understand why....I expect it has to do with
types of distortion as decoded by our ears (or more precisely lack
thereof)..but that's just a guess. Something besides just noise floor is at
work, that's for sure.

I realize this may be drifting off-topic, but I don't know how to move it
somewhere else. I do have to take issue with a couple of your statements,
however.

... the noisefloor on a cd is more ugly than
vinyl/cassette/analog tape, that is why we cover it with dither.
Dither is simply noise similar to cassette noise that is ADDED to the
audio signal it is not the noise floor of the cd.


All reputable digital audio engineers agree that dither must be added for a
digital audio system to be complete. In other words, if you build a digital
audio system without dither, you haven't finished the job. It would be like
building a car without the tires. You might be able to drive it that way,
but you can't say "rubber is just the thing we add to make the ride
bearable". It is for this reason that the inability to properly SACD is a
fatal flaw in my opinion. It's like building a supercharged 12-cylinder 64
valve auto without enough leaving enough room in the fender wells for tires.

That is a complete misunderstanding of the situation. Dither is not
some kind of band-aid, it's an *essential* part of the conversion
process. It does not 'cover' quantisation distortion/noise - it
*eliminates* it. A properly dithered digital recording has a noise
floor which is simply white noise, with none of the ugliness you get
with vinyl or cassette - and of course at least 20dB lower in value
than either of those obsolete media................

Dither is simply noise similar to cassette noise that is ADDED to the
audio signal it is not the noise floor of the cd.


No, you misunderstand its purpose, which is to decorrelate the noise
floor from the signal. It therefore *defines* the noise floor of the
CD. Further, it is most certainly *not* similar to cassette noise, it
is a carefully shaped signal.

As far as SACD (and I really think we are getting away from the spirit
of the initial post) people are way too worried about the
technicalities of the format.


Aside from the technicalities, what is there to discuss?

The noise floor of most microphones is
higher than that of sacd so it will be sort of dithered anyway.


It's higher than that of CD also, so what exactly is your point here?

CDs do however have a 'bare minimum' spec which exceeds that of *any*
analogue master, and converting to DSD from PCM makes a mockery of the
whole principle of DSD.

Eh, Stewart.....what SACD machine is in your system that you are basing your
perceptions on, huh?

Three years ago, two years ago, one year ago more people shared and
promulgated your views...most now own SACD players. They don't say these
kinds of things anymore. You would be better off buying a machine and
disks, hearing the difference, and then spending your engineering talents
trying to determine *why* SACD sounds better rather than denying that it
does.

This is your assertion. It simply doesn't stand up to the listening
experience of SACD users. SACD's are almost always made from direct DSD
recordings (best) or high quality original master tapes (second best). Some
newer pop releases are recorded at 24/192 on a DAW, which also seems to
work. Stuff that was mastered at 24/48 and even some at 24/96 and then
converted to SACD have their "digititus" come through...and these disks are
generally scorned by SACD users for their clearly perceived poor sound
compared to SACDs produced from the other sources.

Correction - most own DVD players which can play SACDs. It's a fine
example of convergent technogy, but it's uncertain how long SACD will
survive on its own.

Surely, Harry, you see that such anecdotal arguments aren't going to carry
weight -- 'SACD users' seem no less immune to expectation biases than
others. Their 'listening experience' is too often not backed up by anything
substantial.

I am convinced. Either that, or our ability to hear differences in noise

I and most others with SACD machines can put an orchestral SACD or a
stringed group of pop musicians on the machine and almost immediately tell
you whether it is a DSD recording or not. DSD recordings have a depth,
ease, and "naturalness" that *no* other medium has. Not tape (which has a
pleasant but artificial "warmth" to it). Not high-rez pcm (which has a
certain flatness to it).

Some
newer pop releases are recorded at 24/192 on a DAW, which also seems to
work. Stuff that was mastered at 24/48 and even some at 24/96 and then

Absolutely not! In many cases the source of the recording was "speculated
about" before it was confirmed. If you hung out around the Hi-Rez group on
Audio Asylum once in a while you might learn something. A case in point is
Sony's SACD of Glenn Gould's Well Tempered Klavier. I bought the disk
early on in my SACD explorations and thought "what the....". It sounded
bright and sterile like a poor cd, totally unlike any other SACD I had
heard. Well, guess what? It *was* a 16/48 "master" from the early eighties
(Sony doesn't say that on the disk). Others had the same experience who
pursued Sony, who finally admitted it was the digital "master". Why Sony
chose it only they know, but they got so much flack over the sound that in a
later release of a boxed set including both of his recorded versions, they
reverted to the taped master of the session.

No they don't. They know and enjoy SACD as a superior music reproduction

up and enjoy.

Note that a

on the fatal flaws of SACD, now that it's all out in the open and

"Fatal flaw" because it requires SACD-wide to do signal processing? The
whole system and its ability to deliver music is what counts. If the system
using SACD-wide still produces superior studio recordings, fine. If it
gives better classical and jazz recording even better. If SACD decoding
results in much less assault on our ears than redbook cd, even better still.
And all three seem to be the case.

Bruno's comments add nothing to what was already known.

And you continue to ignore the end result. A "fatal flaw" that doesn't
affect the end result is not all that "fatal", now is it? Semantics are not
a substitute for listening. I repeat, Stewart, what SACD machine and what
SACDs do you listen to at home, on your reference system?

You would be better off buying a machine and

As ever, you have it back to front, Harry. Having determined that
there is in fact no detectable audible difference, the interesting

I listen. I don't have to concoct convulted theories.

Of course, if you have an amp which is sensitive to the horrific and
endemic RF noise of SACD, then it probably *does* sound worse!


Fortunately, I have avoided such amps for years, as it generally doesn't
take SACD to make them sound unmusical.

I'm referring to a player I can (and have) borrow to use in my own
system. I've listened to DSOTM - which is a superb re-master, even in
2-channel, Ray Brown Trio Soular Energy, Isaac Hayes Hot Buttered
Soul, Billy Joel An Innocent Man, Bruno Walter Beethoven 6, Charlotte
Church, Ormandy Carmina Burana, Szell Peer Gynt/l'Arlesienne/Pictures
at an Exhibition, Michael Jackson Thriller, and Santana Abraxas.

In all cases, the SACD did not sound the same as the CD, due to
remastering, and sometimes the SACD was 'better', sometimes not.
Certainly, there was no *consistency* in the differences, such as
would indicate what one might expect from the technical differences,
such as a more natural percussion on the jazz and rock tracks.

Personally, I'd stack 'Red Book' JVC XRCDs against any of those for
sheer sound quality.

Three years ago, two years ago, one year ago more people shared and

SACD is *not* a substandard of the DVD standard, and most SACD players
are not DVD players. Ownership of a 'universal' player indicates no
preference for SACD, which is what you're trying to claim.

They don't say these kinds of things anymore.

Yes, they do.

That's a belief system, not a reality.

They may be puzzled and not understand why, but they generally shut

That would be because they *believe* that it sounds 'better', which is
fine. If only others would shut up when they have nothing to offer but
mere assertion.......................

Note that a
senior Philips engineer has now also joined in 'blowing the whistle'
on the fatal flaws of SACD, now that it's all out in the open and

There's no such thing - you mean DSD-Wide, which is after all just
another form of PCM, and much more difficult to work with than the
allaround superior 24/192 PCM.

The
whole system and its ability to deliver music is what counts. If the system
using SACD-wide still produces superior studio recordings, fine.


So can CD, so who needs DSD-Wide?

If it
gives better classical and jazz recording even better. If SACD decoding
results in much less assault on our ears than redbook cd, even better still.
And all three seem to be the case.


No Harry, you just *claim* that they are. Have you ever listened to
the superb jazz releases on JVC XRCD?

Bruno's comments add nothing to what was already known.


Quite so - but they come from a senior engineer closely associated
with SACD.

And you continue to ignore the end result.


Nope, you are the one who is attempting to ignore reality.

A "fatal flaw" that doesn't
affect the end result is not all that "fatal", now is it?


No, but it *does* affect the end result, which is of course why even
Sony does *not* use DSD for recording.

Semantics are not
a substitute for listening.


Neither are your baseless claims............

Largely true, but once again you fail to answer the point. Where the
mastering is identical, *no one* has yet shown an ability to tell SACD
from CD under controlled conditions. Given the poor technical
performance of SACD, that's actually pretty good.........

Do you think that the remastering folks might ever turn up and down the

they believe to be the most pleasing result? If so are there (m)any

It is more a limitation of the way the recording is made. 96dB is
pretty decent but rarely acheived.


Very true. A recent discussion between a couple of mastering
engineers said that they're lucky to produce about 40 dB of dynamic
range in a live, acoustic recording, with no compression or any other
funny business going on. A recent review of a DVD-A on
highfidelityreview.com mentions that the producers were very happy to
achieve nearly 70 dB of dynamic range in their recording.

Having said that, there are venues where large dynamic range, beyond
human audible limits, is achievable, if proper precautions are taken
(recording late at night, AC off, hall in a certain configuration).
Two examples are Skywalker Ranch's soundstage and the Meyerson
Symphony Hall in Dallas. The new Walt Disney Concert Hall in Los
Angeles may have similarly impressive figures, given its construction
specs (the hall is decoupled from the streets around it through a
floating concrete slab the hall sits on, for example) and apparent
clarity, but no one's measured it yet.

Having said those two things, one has to be careful with single
numbers like "40 dB", because that number, like SNR and THD+N and
dynamic range equipment specs, is perceptually useless. It doesn't
tell us what the spectrum of the noise is, and hence, beyond the
grossest things, we can't really predict what its effect will be. For
example, in many homes, the measured noise level may be relatively
high, but the distribution tends to be skewed towards the lower
frequencies, so the noise may not necessarily affect midrange
frequencies as much as a single number may lead you to believe. One
also has to be careful about how that number is measured --- is it
relative to digital silence, or only the most silent recorded part of
the recording?

Given more than 100 years of research into the ear/brain function, we

about the uselessness of sighted testing. In fact, while one can never

But your missing it doesn't make it an any

I am convinced.


I believe that the poor audio performance of SACD (on those occasions
where it really does sound different from CD) is entirely due to the
poor RF noise performance.

Either that, or our ability to hear differences in noise
floor (or to have it affect our perceptions of the naturalness of recorded
music) is much greater than previously thought.


Oh, I can hear noise at 20-30dB below the signal, although not
*directly* at the frequencies where this occurs with SACD. IMD
products in the baseband are of course highly audible.........

Also a
lot of people who are mastering for sacd use 192/24 equipment to edit,
dither, normalise etc and then make the final dsd conversion last
thing. This may seem like an impure path but at that resolution it is
fine. 192khz is deliberatly over-spec'd to allow for a bit of give and

CDs do however have a 'bare minimum' spec which exceeds that of *any*

Harry, this is mere assertion, and you know it.

Some
newer pop releases are recorded at 24/192 on a DAW, which also seems to
work. Stuff that was mastered at 24/48 and even some at 24/96 and then
converted to SACD have their "digititus" come through...and these disks are

I learn that lots of people make wild claims about things which have

There have always been, and always will be, poor recordings. This
instance will of course have had nothing to do with the original being
16/48, unless it was an old recording made with poor converters. Hey,
guess what - it was made at the dawn of digital audio, so there's
every chance that it was indeed a technically poor recording - it
might even be undithered.

You'll have to do *much* better than that, Harry!

What are being referred to as "convoluted theories" actually have a very
firm mathematical and digital signal processing basis. I will say that the
"fatal" flaws in SACD might be so small as to be irrelevant in everyday use.
Ten years ago, some respected engineer said that by the time Digital Audio
was all "true" 24-bit, we wouldn't need dither. I don't know if they'd make
the same statement today, but perhaps it's true for all practical purposes.
On the other hand, if I were designing a system, I would want it to be
theoretically flawless, even if the current technology leaves room for
improvement. Otherwise, guaranteed, some group of audiophiles or high-end
mag would "discover" the flaw and make a big deal out of it. Or -- more
likely -- a manufacturer with a marketing agenda would trot the flaw all
over their sales literature, showing how their technology is audibly better.
All of a sudden a whole bunch of high-end enthusiasts would "hear" the
difference! Don't get me wrong, I'm not dissing anybody. I'm a high-end
enthusiast myself. Unfortunately (for me) I'm also an engineer, which takes
all the fun out of it. You can't have opinions about the truth.

Eh, Stewart.....what SACD machine is in your system that you are

basing your
perceptions on, huh?

I have access to a Sony DVP-NS900V, a machine of unusual talent at the
price.

"Having access" is not the same as listening in your own system, is it
Stewart? And what disks have you listened to? Come on, share a little!


I'm referring to a player I can (and have) borrow to use in my own
system. I've listened to DSOTM - which is a superb re-master, even in
2-channel, Ray Brown Trio Soular Energy, Isaac Hayes Hot Buttered
Soul, Billy Joel An Innocent Man, Bruno Walter Beethoven 6, Charlotte
Church, Ormandy Carmina Burana, Szell Peer Gynt/l'Arlesienne/Pictures
at an Exhibition, Michael Jackson Thriller, and Santana Abraxas.

In all cases, the SACD did not sound the same as the CD, due to
remastering, and sometimes the SACD was 'better', sometimes not.
Certainly, there was no *consistency* in the differences, such as
would indicate what one might expect from the technical differences,
such as a more natural percussion on the jazz and rock tracks.


Decent list, but no DSD mastered disk among them, so you are not getting the
best SACD has to offer.

Were you comparing to separate redbook cd's? To a hybrid layer? What
titles did you find cd superior to SACD on, and how would you describe the
difference?

Personally, I'd stack 'Red Book' JVC XRCDs against any of those for
sheer sound quality.


A lot of people have done that .... and with one exception among several
dozen...they prefer SACD. Again, hang around Audio Asylum Hi-Rez for
awhile...and if you want to challenge them, challenge them.

Three years ago, two years ago, one year ago more people shared and
promulgated your views...most now own SACD players.

Correction - most own DVD players which can play SACDs. It's a fine
example of convergent technogy, but it's uncertain how long SACD will
survive on its own.

Last I heard, SACD was a subset of the DVD standard, and SACD players are
therefore logical mates with DVD players. Your point?


SACD is *not* a substandard of the DVD standard, and most SACD players
are not DVD players. Ownership of a 'universal' player indicates no
preference for SACD, which is what you're trying to claim.


Most SACD players today are DVD players as well. The earlier ones (mine
among them) were not but that did not mean that SACD is not a substandard of
the DVD standard....the DVD standard allows for it.

They don't say these kinds of things anymore.

Sure they do - if they have any engineering knowledge.


No they don't.


Yes, they do.

They know and enjoy SACD as a superior music reproduction
system.


That's a belief system, not a reality.


It seems to be a belief system then that spontaneously strikes 9 out of 10
who have heard SACD.


They may be puzzled and not understand why, but they generally shut
up and enjoy.


That would be because they *believe* that it sounds 'better', which is
fine. If only others would shut up when they have nothing to offer but
mere assertion.......................


I see. I see. They believe it sounds better but they refuse to talk about
it because they can't explain it to their engineering brethren like
yourself. Is that what you are saying?

I say good for them...they trust their ears over dogma.

Note that a
senior Philips engineer has now also joined in 'blowing the whistle'
on the fatal flaws of SACD, now that it's all out in the open and
company loyalty is no longer an issue.

"Fatal flaw" because it requires SACD-wide to do signal processing?


There's no such thing - you mean DSD-Wide, which is after all just
another form of PCM, and much more difficult to work with than the
allaround superior 24/192 PCM.


Yes, DSD-wide, sorry. And they use it because it (the whole DSD/SACD sytem
sounds better). In the early days they went to tape and back. Nowadays,
some use 192/24 on a one-time basis. But where available all-DSD is still
the first choice.

The
whole system and its ability to deliver music is what counts. If the

system
using SACD-wide still produces superior studio recordings, fine.


So can CD, so who needs DSD-Wide?


Anybody who wants better sound.

If it
gives better classical and jazz recording even better. If SACD decoding
results in much less assault on our ears than redbook cd, even better

still.
And all three seem to be the case.


No Harry, you just *claim* that they are. Have you ever listened to
the superb jazz releases on JVC XRCD?


I haven't, but many people have. And they virtually all feel SACD is
superior to XRCD, even XRCD24, even though that is in turn better than
ordinary cd.

Bruno's comments add nothing to what was already known.


Quite so - but they come from a senior engineer closely associated
with SACD.


Yep, so? All he is testifying to is that they have to use DSD-wide for
signal processing.

And you continue to ignore the end result.


Nope, you are the one who is attempting to ignore reality.


The reality is most people who have heard SACD end up buying a SACD player.

A "fatal flaw" that doesn't
affect the end result is not all that "fatal", now is it?


No, but it *does* affect the end result, which is of course why even
Sony does *not* use DSD for recording.


Bull****. Virtually all their classical recording done in the last three
years has been DSD.

Semantics are not
a substitute for listening.


Neither are your baseless claims............


I see...my opinion supported by fact in some aspects is worthless, while
your opinion supported by fewer facts and incomplete listening is superior,
is that it?

I repeat, Stewart, what SACD machine and what
SACDs do you listen to at home, on your reference system?


Asked and answered.


Good. Now fill in the blanks, please.

You would be better off buying a machine and
disks, hearing the difference, and then spending your engineering

talents
trying to determine *why* SACD sounds better rather than denying that

it
does.

As ever, you have it back to front, Harry. Having determined that
there is in fact no detectable audible difference, the interesting
thing is why SACD does not sound noticeably *worse*, given its
obvious technical inferiority...............

I listen. I don't have to concoct convulted theories.


But you do make wild assertions based on your personal perception
under uncontrolled conditions.


Wild only to you, Stewart. Not to most who have heard SACD.

Of course, if you have an amp which is sensitive to the horrific and
endemic RF noise of SACD, then it probably *does* sound worse!


Fortunately, I have avoided such amps for years, as it generally doesn't
take SACD to make them sound unmusical.


Largely true, but once again you fail to answer the point. Where the
mastering is identical, *no one* has yet shown an ability to tell SACD
from CD under controlled conditions. Given the poor technical
performance of SACD, that's actually pretty good.........


Well, where I own identical recordings from identical mixes (Swing Live, and
3 Doors Away from the Sun), the SACD is even superior to DVD-A, but this
might be due to the difference in players. And on current remixes using the
Meitner Box which usually outputs DSD and high-rez PCM simultaneously, the
SACD layer beats the CD layer (listen to Vince Guardi's Charlie Brown
Christmas and you'll see what I'm talking about). I'm seeking opinions
from Universal Player owners now on the Audio Asylum to see what they might
have to say about this phenomenon.

Maybe you're hearing the "fatal flaw" and you *like* the sound. Sort of like

I strongly agree, I don't claim to have golden ears, but I can hear
the improvement. It's not subtle.


And assuming it isn't, you know it's due to SACD...how?

I listen. I don't have to concoct convulted theories.

You're right but his theories aren't that bad. They're kind of
convincing actually, but my ears are a lot more convincing!


It's one thing to be convinced that you hear something; it's another
to be convinced you know *why* you're hearing it.

Do you think that the remastering folks might ever turn up and down the
dials, switches, etc. in an attempt to produce a sound that would offer what
they believe to be the most pleasing result? If so are there (m)any
available examples. I'd like to lay me ears on a couples of them!

What are being referred to as "convoluted theories" actually have a very
firm mathematical and digital signal processing basis. I will say that the
"fatal" flaws in SACD might be so small as to be irrelevant in everyday

use.
Ten years ago, some respected engineer said that by the time Digital Audio
was all "true" 24-bit, we wouldn't need dither. I don't know if they'd

make
the same statement today, but perhaps it's true for all practical

purposes.
On the other hand, if I were designing a system, I would want it to be
theoretically flawless, even if the current technology leaves room for
improvement. Otherwise, guaranteed, some group of audiophiles or high-end
mag would "discover" the flaw and make a big deal out of it. Or -- more
likely -- a manufacturer with a marketing agenda would trot the flaw all
over their sales literature, showing how their technology is audibly

better.
All of a sudden a whole bunch of high-end enthusiasts would "hear" the
difference! Don't get me wrong, I'm not dissing anybody. I'm a high-end
enthusiast myself. Unfortunately (for me) I'm also an engineer, which

takes
all the fun out of it. You can't have opinions about the truth.


I'm not speaking of the presence of high-frequency noise....in the
ultrasonic range or the need for dsd-wide for signal processing. I'm saying
it is convoluted to use those arguments to claim that SACD doesn't sound any
better than CD.

The proof is in the listening...and a growing number of audiophiles are
reaching the conclusion that SACD sounds more like real music than cd. This
seems especially true of the older generation raised on vinyl and whom
appear more experienced with attending classical and acoustic concerts.
Those among the younger generation who seem not to have heard much music
other than CD and rock concerts sometimes don't like SACD because they find
it "soft". They lament the lack of "edge" that many CDs have...they think
music should have this edge. It should not and in real life does not.

Nobody in the engineering community has yet explained *why* SACD strikes
most experienced acoustic concert goers as more lifelike both upon first
hearing and upon repeated hearing. Yet this is the most common reaction
among people when they first hear it. Until this phenomenon is explained,
the assertion that SACD is inferior because of its shifted noise level and
use of SACD-wide signal processing is just irrelevant to the real issue that
interests audiophiles. Why does it sound so good? The`only`obvious
explanation is the reduced mid-frequency and lower-frequency noise floor.
Yet conventional theory says the CD noise level is already below the level
of audible perception..as Stewart keeps pointing out. Something is amiss in
our knowledge base.

So don't have opinions about the truth. But find the truth. My only gripe
is that the energy spent by people like Stewart trying to convince us that
we are hearing things because he can't explain it with current engineering
knowledge is misplaced: it would be better spent honestly seeking to get at
the answer as to "why". And that is especially annoying when he has hardly
the experience with it that many others do. Perhaps the neurophysioligists
and auditory specialists rather than engineers will have to be the ones to
provide the answers.

As I've mentioned in this group before (at least a couple of times)
it's much easier to demonstrate the inferiority of CDDA rather than
the SUperiority of SACD, if indeed that is the case. One does this by
recording the output of the SACD recording, and showing that it cannot
be re-recorded in CDDA without audible degradation. i.e. you can't
slip such a copy by an SACD enthusiast without him noticing.

Even better would be comparing the SACD recording to the signal from
the analog tape from which it's made. If the SACD output can be
reliably identified--and preferred--then we have something interesting
to pursue!

Merry Xmas,

Not moving the goalposts. Just common sense if you are going to criticize
legitimately.

And you know perfectly well there are DSD recordings. The first year or so
the workstations were pure one-bit DSD and most recording to this day
utilizes no signal processing but records "straight in". Again, you are
substituting semantics to obscure the basic truth.

Were you comparing to separate redbook cd's? To a hybrid layer? What
titles did you find cd superior to SACD on, and how would you describe

Both to separate CDs and the hybrid layer, where available. I'm not

In other words, you've got something to hide. Could it be that you haven't
done many (any?) careful comparisons. Could it be that you have avoided DBT
but are still offering assertions as "truth". Most of us on this and other
forums are perfectly willing to discuss specific recordings and our
impressions of them and comparisons to them. And we offer these "opinions"
as just that, observations, impressions, opinions. Nobody is "locked in".
In that way we can share impressions: in that way consensus or arguments can
ensue; and in that way one can judge for themselves how universal or "nicne"
a set of impressions are and if there are differences, whether or not there
are variables that might explain them.

Personally, I'd stack 'Red Book' JVC XRCDs against any of those for
sheer sound quality.

lot of them, including some very technically savvy ones) with much more
experience with SACD who have reached other points of view are simply not
worth listening to? How do you spell "threatened"? If you opened yourself
up a little, you might be surprised that there *are* others who share your
view....they just happen to be in a distinct minority.

Except that there is no consensus at all in support of your view. There
are at least as many recording engineers who prefer SACD as prefer 24/192
based on an informal sampling at AES. Many work now with 24/192 because
that is what they have but are looking forward to getting their SADIE and
GENELEC workstations.

In the early days they went to tape and back. Nowadays,
some use 192/24 on a one-time basis. But where available all-DSD still

They are assertions and opinions and have never been offered as proof. You
are the one making technical claims *aginst* my opinions and assertions. I
have offered support and disclosed the basis for my assertions and opinions.

such as a more natural percussion on the jazz and rock tracks.

Decent list, but no DSD mastered disk among them, so you are not getting

the
best SACD has to offer.


Yeah fine, Harry, you'll always move the goalposts, just as with the
DBT threads. Did you miss my comment that there's no such thing as a
true DSD recording?


Not moving the goalposts. Just common sense if you are going to criticize
legitimately.

And you know perfectly well there are DSD recordings. The first year or so
the workstations were pure one-bit DSD and most recording to this day
utilizes no signal processing but records "straight in". Again, you are
substituting semantics to obscure the basic truth.

Were you comparing to separate redbook cd's? To a hybrid layer? What
titles did you find cd superior to SACD on, and how would you describe

the
difference?


Both to separate CDs and the hybrid layer, where available. I'm not
going to get into a detailed breakdown, it would be pointless with
you.


In other words, you've got something to hide.


No Harry, it's a given in any 'debate' with you that you'll jump
around all over the place to score points, regardless of the basic
truths of the matter. I am only interested in sound quality, and to my
ears, SACD simply doesn't offer *any* advantage over straight CD -
aside from the multichannel ability. Of course, we have the even
better DVD-A for multichannel, so no problem with real progress. DSD
has already been shown to be a technical dead end for recording, and I
doubt that SACD will last that much longer.

Could it be that you haven't
done many (any?) careful comparisons. Could it be that you have avoided DBT
but are still offering assertions as "truth".


Nope, I *always* do DBTs where differences are subtle. While this
isn't particularly easy with CD/SACD, I do my best to 'bias-proof' the
comparisons. I am *not* going to get into a pathetic 'bar by bar'
argument with you, when I know that you have done no such blind
comparison.

Most of us on this and other
forums are perfectly willing to discuss specific recordings and our
impressions of them and comparisons to them.


Sure you are - and they are pointless lip-flapping.

And we offer these "opinions"
as just that, observations, impressions, opinions. Nobody is "locked in".
In that way we can share impressions: in that way consensus or arguments can
ensue; and in that way one can judge for themselves how universal or "nicne"
a set of impressions are and if there are differences, whether or not there
are variables that might explain them.

Personally, I'd stack 'Red Book' JVC XRCDs against any of those for
sheer sound quality.

A lot of people have done that .... and with one exception among several
dozen...they prefer SACD. Again, hang around Audio Asylum Hi-Rez for
awhile...and if you want to challenge them, challenge them.


I've done my own listening comparisons, and I'm well aware of the
technical drawbacks of SACD, so I'm not interested in the weird and
wonderful opinions of the inmates of the Audio Asylum.

In other words, those intelligent listeners on other forums (and there are a
lot of them, including some very technically savvy ones) with much more
experience with SACD who have reached other points of view are simply not
worth listening to?


Not if they haven't done *blind* comparisons, no.

How do you spell "threatened"?


As above...............

If you opened yourself
up a little, you might be surprised that there *are* others who share your
view....they just happen to be in a distinct minority.


You seem to have this impression that I care. Without the results of
*blind* comparisons, these opinions, whether agreeing or disagreeeing,
are of no value to me.

They know and enjoy SACD as a superior music reproduction
system.

That's a belief system, not a reality.

It seems to be a belief system then that spontaneously strikes 9 out of 10
who have heard SACD.


The MacDonalds argument never works, and the jury is certainly out
among audio industry professionals.............

That isn't a McDonald's argument. It is rather a Zagot guide....by people
who've actually eaten at the restaurants in question.


Industry professionals can't agree on SACD, so the sighted opinions of
a vocal few amateurs are hardly of interest to anyone who wants some
*real* information on the subject.

They may be puzzled and not understand why, but they generally shut
up and enjoy.

That would be because they *believe* that it sounds 'better', which is
fine. If only others would shut up when they have nothing to offer but
mere assertion.......................

I see. I see. They believe it sounds better but they refuse to talk about
it because they can't explain it to their engineering brethren like
yourself. Is that what you are saying?


Nope, I'm saying that they've never done comparisons under controlled
conditions.

Hasn't kept them from buying machines and SACDs and enjoying them, and for
the most part preferring them over ordinary CD.


And your point is? Aside from RF noise, SACD is certainly not *worse*
than CD, so why wouldn't they enjoy them? Of course, without proof of
*difference*, any expressed preference is simply label snobbery.

I say good for them...they trust their ears over dogma.


No Harry, neither you nor any of your pals actually *trust* their
ears, only their eyes...................

Ho hum. Ho hum. Same old record, intended to substitute for "where's the
proof:" via DBT. Where's you *proof* that SACD is no better than CD?


My blind comparisons suggest that mastering is *vastly* more variable
than any differences which you could track down to extended bandwidth.
The extended resolution at low frequencies is of course irrelevant,
since 16 bits is already much more than is on any master tape. Note
that most '24 bit' PCM converters are actually 1-bit devices, so they
are in effect just the same as DSD. Note also that the best are
low-bit hybrids, just like DSD-Wide, and for the same reasons.

Note that a
senior Philips engineer has now also joined in 'blowing the whistle'
on the fatal flaws of SACD, now that it's all out in the open and
company loyalty is no longer an issue.

"Fatal flaw" because it requires SACD-wide to do signal processing?

There's no such thing - you mean DSD-Wide, which is after all just
another form of PCM, and much more difficult to work with than the
allaround superior 24/192 PCM.

Yes, DSD-wide, sorry. And they use it because it (the whole DSD/SACD sytem
sounds better).


No, they use it because DSD doesn't work, and company pride wouldn't
allow them to junk it in favour of the allaround superior 24/192 PCM.

Except that there is no consensus at all in support of your view.


Nor in support of yours..................

There
are at least as many recording engineers who prefer SACD as prefer 24/192
based on an informal sampling at AES.


Quite so - as I said already. Nothing like the '9 out of 10' that you
were claiming for your Audio Asylum pals.

As previously noted, straight DSD is *never* used nowadays, and
DSD-Wide simply has no rational place when 24/192 is available.

DSD-wide is still preferred over the alternatives by most of those with
access to the technology. They think it sounds better. You don't believe
me, go right ahead and ask them.


You already said that it's a 50/50 split in the AES - try to keep your
story straight, at least in the same post..............

And I have asked them - they are as divided as you earlier suggested.

A "fatal flaw" that doesn't
affect the end result is not all that "fatal", now is it?

No, but it *does* affect the end result, which is of course why even
Sony does *not* use DSD for recording.

Bull****. Virtually all their classical recording done in the last three
years has been DSD.


No, they use DSD-Wide, which is *not* true DSD. They simply refuse to
lose face by switching to the superior (and much simpler) 24/192 PCM.

This is totally irrelevant to the sound of the final product.


Not if the final product is a 24/192 DVD-A, it's not! With that
excellent standard, you truly can have an *exact* copy of the original
studio master, which you can't with SACD.

Harry, until you listen under DBT conditions, these are mere
assertions with *no* evidential base whatever. Take them to the
Asylum, by all means....................


They are assertions and opinions and have never been offered as proof. You
are the one making technical claims *aginst* my opinions and assertions. I
have offered support and disclosed the basis for my assertions and opinions.


No, you've just claimed that others share your opinions. This has no
value if those opinions are based only on sighted listening.

Here goes the old "give me proof via DBT" or you are not allowed to present
your opinion in opposition to mine gambit. Moderators....???


I'm not presenting an opinion - I'm giving you facts about DSD, facts
about SACD, and the inconclusive results of my blind comparisons. Just
what reliable and repeatable information are you offering in return?

Merry Christmas, one and all!
