Here we go again...

I need to correct one major error in your statement... The "Pseudo Voce"
recordings do not contain /any/ added reverberation. What you hear is how
acoustic playback of these /acoustically dead/ recordings would sound in an
acoustically appropriate listening space. This is no more "added
reverberation" than the sound of a concert hall is "added reverberation".

Ignoring the fact that we don't really know /exactly/ how these singers
sounded, why should an acoustical reproduction of an acoustical recording
/necessarily/ be less accurate than one transcribed electrically?

This is /not/ a rhetorical question, nor is it a question that has a simple
answer. Nimbus is /in principle/ playing the recordings as they were
intended to be played. The /only/ valid criticism (that I can think of) is
that their reproducing mechanism does not match that of any particular
record company's. (One assumes that a Columbia disk would have the best
fidelity on a Columbia player, an RCA on an RCA, and so on, given that
recording and playback would have been tweaked for the best fidelity or the
company's preferred "sound".)

Transferring the recording electrically does not automatically resolve these
issues. The engineer still has to decide on an overall EQ that gives the
perception of flat response. As for horn and cutter-/playback-head
resonances... he has to isolate and correct these.

Rather than continue to argue this, I would hope that some experienced
transfer engineer would tell us about his experiences with /acoustical/
recordings. I'm perfectly willing to change my opinion -- but I would like
some hard, objective facts first.

---------------
The digital transfers of (most of) Caruso's recordings were individually
equalized so that the detailed tonal balance matched that of modern
electrical recordings of the same works. To my ears, the sound of Caruso's
voice /did not/ match that of what I was used to hearing. It didn't sound
like him, and I really didn't like the voice. Yet people who had heard
Caruso sing live proclaimed the new transfers as more-accurate renditions.

---------------
Some comments on mono recordings... I generally don't like them, partly
because few are of truly high fidelity (the same could be said about too
many stereo recordings!), and, of course, they lack the spaciousness of
stereo. Generally speaking, though, the better the playback system, the
better mono recordings sound -- even more so than stereo recordings. And...
If you have a hall synthesizer, you can generate stereo ambience to the
sides and rear, which grossly improves the sound quality, without in any way
degrading the original.

The reverb is not in the recordings themselves. Therefore, it is added.
By which method is not important, and does not change the fact.

How do we know that? Does it say so on the original record labels, the way
some rock records from the '60s said "PLAY THIS RECORD LOUD"? (And I'm
sure the folks at Beltone have enjoyed their uptick in sales ever since.)

The concept of being required to hear/view something the way the original
hearers/viewers did is utterly ridiculous. It is like going to view the
antiquities at the Getty, and a guard stands at the door to remove the
eyeglasses from anybody who dares to try to get in wearing them.

I say it's broccoli, er, added reverb, and I say the hell with it.

Well, it sounds less like an actual person singing.

But there is a valid artistic argument, in that the playback method very
accurately reproduces what a person actually listening to a record in
1920 would have heard.

The question is whether you, as a listener, want to recreate the experience
of listening to a record in 1920, or want to recreate something as close as
possible to the original performance. (And sadly, as close as possible to
the original performance isn't really very close anyway.)

No, it is a _very_ valid criticism to say that their playback method is
less accurate at reproducing the original sound in the original studio.

However, since electrical playback methods are also very inaccurate at
doing that, the baseline isn't that much lower.

There are no hard objective facts. I can take an acoustic disc and I can
remove a couple of the worst horn resonances. But you still have a recording
that has a lot of horn artifacts, mechanical cutting artifacts, and on top
of that it's usually performed with odd arrangements, instruments, and
orchestral configurations in order to suit the limitations of the recording
horn.

So... even if you WERE to reproduce the sound in the original studio
accurately, it would still be very different than the sound that you
would hear from the same performers in concert.

Given that, you could make a valid argument that since it would be
impossible to reproduce such a nonexistent concert, that the most
authentic thing to do would be to make an accurate reproduction of
what a period disc playback would have sounded like.

This is referring to the Stockham work... and Stockham actually started
doing this before the beginning of the digital era. He wound up with
one of the first digital notch filter systems and he notched the hell out
of anything that looked like a narrowband resonance. He killed horn
resonances, room resonances, and possibly body resonances.

I don't like the way those transfers sound either, but again I think he
took a valid technique and became a little bit too enthusiastic about it.
This is fairly common when any new technology appears.

The honest truth is that all of this stuff is a judgement call, since it
is clearly impossible to make anything approaching an accurate reproduction
of the original performance. So it becomes a matter of what the end
listener is most willing to live with.

If you don't like the Stockham reissue, or you don't like the Nimbus
reissue, or if you prefer them... they are all valid artistic judgements.
And it all comes down to artistic judgements.

Personally I would hope you would ignore all this stuff and start buying
more later big band radio transcription reissues because I need the money.

Norman White, who supervised the Nimbus acoustic transfers is a friend
of mine. Before joining Nimbus he was an opera singer and before that
he was an electronics engineer, so he is fairly well qualified to know
both sides of the arguments.

I agree that those transfers are a matter of taste, but if Norman can't
get them to sound good to someone who likes that sort of thing, I would
be very surprised if anyone else could do any better.

Acoustic recordings were intended to be played back acoustically. It is even
reasonable to suggest that Columbia '78s' sounded better played in a
Grafonola than in a Victrola. Nimbus' superhorn is a questionable element in
the re-recording chain, and their highly revererant room is fairly silly,
but those are another story.

So when I switch on my JVC hall synthesizer, the net result is /less/ like
the sound of a live orchestra? (Let's not get into an argument over the fact
that the hall synthesizer is optional, whereas the ambience on the Nimbus
disks is part of the recording. It has nothing to do with this particular
point.)

Agreed. And the issue is a sticky one, because acoustical recordings were
generally "dead" because reverberation blurred the sound.

Note, however, that there's a difference between reverberation /in the
recording/, and reverberation /in the room/ where the recording is being
played. The latter comes from the same direction as the direct sound (which
is generally undesirable), while the latter comes from multiple directions,
which a stereo or surround recording captures.

But that isn't necessarily what we want. Would Carouso, Sherman-Tank, et al,
have objected to someone listening to their recordings from 10' or so back,
and letting the room add some "bloom" to the sound? I don't think so. They
probably would have preferred it. (Does anyone know for sure?)

So we sort-of agree. Okay. So -- and this is an open question -- how would
you go about doing that? Nimbus has given us one possible answer. Are there
any others?

Well, that's true. But if you don't want that, don't buy the reissue made
that way.

I don't personally like the process, so I wouldn't buy those reissues at
all. But that doesn't mean the process isn't artistically valid or that
someone else might not prefer them.

I think the Nimbus process is very well done for what it is. You could
make arguments that a smaller horn would be a better idea and I would tend
to agree with that, though.

I like them because I enjoy the "bloom". I also have six-channel Ambisonic
playback. (UHJ recordings can sound overly reverberant in stereo. They
actually sound less reverberant when properly decoded. The same was true of
SQ recordings.)

I don't remember why they chose such a large horn. Bass? Volume level?

The ambience on the Nimbus CDs is not a part of the recordings
themselves. It is the result of the method used to play the discs: an
unusually large machine in a very large room, recorded with
microphones distant enough to pick up the considerable resonance of
the room and add it to the sound of the record being played. The
resonance is a part of the recording only in the sense that that is
how it has been reproduced. It's not on the discs themselves.

But the original recordings had no resonance. No reverberation.
Acoustical recordings are acoustically dead. There is no resonance.
None. I own many hundreds of them and am speaking from personal
experience derived from playing them. Caruso, Schumann-Heink,
Chaliapin, Galli-Curci, Battistini, Fritz Kreisler, Elgar conducting,
whoever: the recordings were made in acoustically deadened studios.
Adding resonance to the records' sound is not recreating something as
close as possible to the original performance. It is adding a modern
sonic element to the evidence we have of the original performance,
evidence which is derived from and recorded with an admittedly crude
technology (i.e. the acoustical process).

I can only think that a modern artificial reverberation machine,
which you mentioned, is essentially no different from re-recording
acoustical recordings in a modern setup when they are played in a very
large room and the results are recorded so as to include the resonance
of the room, as Nimbus did. They are different methods, one electronic
and the other based on acoustics, but are both a doctoring of the
sound of the original sources.

I agree, and I don't like either of them. At least Pristine allows you the
choice of one or the other, and you only have to pay for whichever one you
want. Testament (at least with their latest Klemperer Mahler 2nd release)
makes you take both and pay for both. Nimbus gives you no choice at all.

And indeed I don't. But I should be very cross indeed if the proliferation
of Nimbus tiled-bathroom recordings were to crowd the others out of the
marketplace. I believe I've seen them on iTunes; I wonder how they sell?

Nearly all of those were recorded by the big companies and are classical
repertoire. There were some acoustic recordings made in reverberant
surroundings, although most of the ones I have heard were on recordings
of popular music, so you might not have encountered them.

Columbia in the UK used a wood-panelled recording room which boomed
badly. You might have mistaken that for a recording fault, but it was
actually an attempt to get as much bass as possible into the horn. It
wasn't a very good acoustic, but it certainly doesn't count as 'dead'.

You need a really effective de-clicker and complex equalisation before
you can begin to hear the sound of the recording room through the noise
and frequency distortion. Many digitally de-clicked reissues of both
acoustic and electrically-recorded discs have the reverberant 'tails'
cut off as they disappear into the noise, but the tails were there on
the originals and you could hear them even as they dived below the noise
level.

And MUCH of they reason why they were recorded in such a dead environment
was to get the optimal intellibility from a recording that would be played
back through a big resonant horn.

ALL of these recordings have very artificial sounds and were made in
very artificial environments, because of the manner in which they were
expected to be played back.

So NO possible playback can ever be natural.

I'll pick the noise over the chopped tails any day, but that is just me

whoever: the recordings were made in acoustically deadened studios.
Adding resonance to the records' sound is not recreating something as
close as possible to the original performance. It is adding a modern
sonic element to the evidence we have of the original performance,
evidence which is derived from and recorded with an admittedly crude
technology (i.e. the acoustical process).

Isn't there some confusion here between "performance" and "recording"? The
lack of ambience was not so much an aesthetic decision as it was an acoustic
one.

By the same reasoning, I shouldn't be using a hall synthesizer.

Except, of course, that I have the choice of using the synthesizer. The

I'm going to be fussy about this, and say that the people who made the
acoustic recordings would have wanted them to be heard in a room that added
what was missing.

The output of the hall synthesizer goes to separate speakers -- it does not
pass through the main speakers. You also have full control of it. The reason
you don't like such processing is that you've probably never heard it used
correctly. When it's set up and adjusted correctly, you aren't aware of the
enhancement -- until it's shut off. I wish I could give you a demo.

At this point I'd like an example or two of reverberant Nimbi. I just
listened to The Golden Age of Singing Vol 4 and didn't notice excessive
echo.

When I worked at a radio station (WFMT in Chicago), a couple of
Caruso cuts were scheduled from Nimbus CDs. I thought the basic sound
reproduction was very good, very similar to what I got from the
original discs; but the added resonance of Nimbus's room made it sound
as if Caruso were singing in the empty Concertgebouw or Boston's
Symphony Hall and recorded from a distance in both cases. And that
resonance is not a part of the original discs. But try Caruso if you
can, and see what you think.

And the recording of this acoustic gramophone sounds no more like
being in the room with it than a recording of a grand piano in that
room sounds like being in the room with that piano.

In fact, many acoustic vocal recordings are not "acoustically dead." A
vinyl strike from an original metal pressing part played with a modern
pickup can pick up room sound (and some vocal "bloom") that is partly
submerged in the noise of a shellac pressing. In Nimbus' approach,
these mechanical noises (and any original room sound) are submerged in
the reverberation of their recording space.

In Read & Welch's "From Tin Foil to Stereo" (1959, 549pp Howard W.
Sams, Pub.) You will find this: "The Columbia recording experts (ca
1908) devoted much of their effort to record the difficult bass
registers and the resonance of the recording studio..." (page 184).

Every model from every brand of acoustic record player had a different
sound. Some horns were made of wood, some from metal, almost all of
them had different shapes. Console machines had a variety of patented
interior folding horns. Reproducers were constantly being upgraded and
tweaked to achieve the most brilliant and loudest sound.

The modern sound engineer can resolve these issues if he/she uses his/
her ears, and knows what to listen for. Anyone who has heard any of
Ward Marston's historic vocal transfers, for instance, will know this
is true.

The one size fits all Nimbus approach (they even used that acoustic
playback system for electrical records!) unfortunately falls short in
every respect.

Not really. Those comments were based on my personal experience of
operating a de-clicker and listening to the results of other people's
attempts.

The comments on recording rooms are the combined results of 'reading
between the lines' of lots of different articles, listening to lots of
acoustic recordings and looking closely at the few photographs which are
available from that era.

Yes! Leaving side the descriptions of Nimbus's acoustical setup in
their CD booklets, which make it seem like something very, very
special, acoustical reproduction could be complex. One has only to
read The Gramophone pre-1926 to see the articles, even ads, advocating
various devices to improve reproduction. As I recall, "The Lifeboat,"
some kind of rubber gasket for tone-arms, was highly recommended for
altering ("improving") reproduction. And of course there was the
needle issue: "Loud"? "Medium"? "Soft"? One could buy any of them to
give different playback sound. Not to mention "fibre" -- cactus or
something else? The Phonograph Monthly Review in the USA was the same
after 1925.

The idea that just playing an acoustical recording on an acoustical
machine automatically resolves all reproduction questions of records
made that way is as fallacious as saying that a Fairchild or G-E or
Grado early stereo LP cartridge yields the same sound as a Shure V-15-
V or another top-of-the-line recent stereo one.

Indeed. And as I think others posted about this earlier, Thomas
Stockham (for we are talking about his 1970s/early 80s RCA LPs) was
quoted -- as I recall -- as saying that he fed the sound of Jussi
Bjoerling's voice into his computer and instructed the computer to
deconstruct the sound of Caruso's acoustical recordings and
"reconstruct" the voice in Bjoerling's vocal image. Because he
(Stockham) thought their voices sounded similar, and he wanted his
computer to recreate Caruso's voice as it would have sounded -- as
sung by Jussi Bjoerling. In Stockham's mind.

That is at least what I remember; and I am willing to be corrected
if my memory is faulty.

That sounds Just Plain Weird, as computers of that era weren't powerful
enough to do such things quickly. It's also aesthetically questionable, as
why would anyone want to make Caruso sound like Bjoerling? Or vicky-versy?

My understanding is that if, say, a Caruso recording of "Nissan datsun" was
being transferred, a modern recording of it was compared with the Caruso to
find the differences in "energy response" -- at what frequencies or bands
the modern recording had (relatively) more or less energy than the acoustic
recording. The acoustic recording was then EQ'd accordingly.

The "catch" of course is that some of these differences might represent
/real/ differences in the sound of their voices, rather than
recording-process errors. The effect would be to make Caruso sound more like
Bjoerling. Or whoever's recording was being used as a reference.

Thanks! I'll have to look for online samples, as the Nimbus Caruso I
have isn't from the specific collections. I did enjoy hearing the
Pearlfisher tracks on Highlights from Faust and French Opera with
Caruso, Farrar and Journet. Definite horn resonances but not excessively
reverberant, as far as I can tell without reference to a dry transfer.

The lack of ambience was an aesthetic decision based upon how the original
recordings were expected to be played back. Since we are not playing those
recordings back in the same way, that is not necessarily a thing we should
avoid trying to alter.

>By the same reasoning, I shouldn't be using a hall synthesizer.

You, however, are playing back modern recordings that are intended to be
played back in a somewhat dry room through two speakers, and consequently
using a hall synthesizer on them is NOT appropriate and is shameful
disregard for the wishes of the original producer. (Unless you are playing
them in some other way than intended, like through headphones for instance.)

Possibly, but that is not necessarily an argument for the Nimbus method,
so much as an argument for doing whatever other tailoring might make the
sound quality more pleasant.

I think what you are hearing isn't the resonance of the room but the
resonance of the playback horn and the playback diaphragm arrangement.

And no, it wasn't a part of the original discs, but it _was_ a part of
what a typical listener of those recordings a century ago would have
heard.

I don't like it at all, but it _is_ authentic.

This is ONE of the techniques that Stockham fooled around with, and there
was an AES conference paper on the subject. That technique was not used
on the RCA LP (and later CD) reissue that Stockham worked on, though.

Stockham didn't do anything quickly, he did things in short pieces with
enormous long runs on very small datasets. He was in every way one of the
great pioneers of digital recording and digital signal processing for audio.

And, sadly, everything I ever heard from his studio sounded pretty awful.

Right. On top of which the acoustic recording system was fearfully nonlinear
which means the relative frequencies at one level may be different than those
at a different level. So the whole idea is pretty misguided. Oh, well.

I assume your tongue is planted firmly in your cheek. (I hope it is!) Stereo
recordings cannot correctly reproduce lateral sounds. The synthesizer
generates rear and lateral sounds (according to measurements made in real
halls), and presents them through rear and side speakers. The result is a
great improvement in the illusion of realism, and this is done without in
any way altering the original recording.

September 30th 10, 01:12 AM
It strikes me that adding room characteristics to an old recording
carries with it a fundamental longterm flaw. That is, presumably it is
being done because technology has improved and so we are able now to
add some depth to the recording (for whatever reason). Well, wouldn't
it stand to reason that technology will continue to improve, and therefore
wouldn't it be wiser to simply provide the recording in it's fullest,
original detail (i.e., flat), so that said improved future technology
wouldn't have to also wrestle with undoing the (then) inferior tamperings
that we did?

In this case, I think I'd rather have the cleanest, untampered recording
possible, and I could add my own processing during playback if I really want
to hear it that way.

That's a perfectly reasonable point of view. But just try to get an
"audiophile" to purchase a room synthesizer and additional speakers. I would
guess that less than 1% of audiophiles use such devices -- which are no
longer manufactured -- despite the improvement they bring.

I don't think we're talking about archival preservation as far as
Nimbus is concerned. They just wanted to make acoustic records more
palatable to listeners who would normally avoid historic recordings.

As long as original pressings of historic recordings exist in
collections and archives, there will probably be some new device or
computer program developed that will reduce all of the noise and
retain all of the signal.

If you want to hear what the acoustic process was capable of
capturing, listen to "The Edison Trials" on Marston Records. These
vocal test recordings were blessed by never having been played until
they were transferred several years ago. There are recordings from
1912 that sound like electrical recordings with lots of room sound
ambience. Amazing stuff.

It's only _slightly_ in cheek. Because then we get to the question about
whether fake lateral sounds are worse than none.

I'm not sure the improvement is "great" and I have seen the technique
used since the days of the Fisher Spacexpander.

But it's an example of the kind of alteration unforseen by the original
engineers. If they knew you were going to do that, they might have mixed
very differently.

For archival storage, this is absolutely the case. The main goal is to
do no wrong and provide as close as possible to the original medium.

But for distribution copies this is not necessarily the case.. as long
as there is a best-possible copy somewhere, making distribution copies
that are more listenable (if less accurate) is a reasonable decision to
make.

The world of online downloading should make this possible... you should
be able to choose which distribution version you prefer and pick your
choice of an unprocessed or several different processed versions. This
is where online distribution really can shine and provide added value to
the end-user over CDs or LPs.

It's not fake. It's /supposedly/ a good approximation of what you'd hear in
a specific hall. (On the JVC and Yamaha synthesizers, hall #1 is the
Concertgebow.)

The SpaceXpander? You're kidding! Boing, boing, boing, boing.

The difference is huge. You'll obviously never heard a proper demonstration.

A valid point, perhaps. The "great killer of young recordings", though, has
long been artificial ambience /mixed in/ to the stereo channels.

Oddly, the synthesized ambience makes the recordings sound /less/
reverberant, /lower/ in subjective coloration, and generally reveals /more/
detail. Clearly, adding synthetic ambience "does something" that the ear
appreciates.

Full agreement here, which is one of the reasons I buy recordings on the

The Mapleson Cylinders did not have the benefit of being hidden away unplayed
for many years, but I certainly get a feel for what the ambience in the old

No offense, but where did you get that? I was talking only about hall
synthesizers.

Oddly, the best way to minimize the effect of the reverb is to play the
Nimbus recordings through a proper Ambisonc setup. As I said in an earlier
post, this moves the ambience to where it's "supposed" to come from, which
reduces the sense of excessive ambience. The same is true of SQ recordings.

The same should be true, to a lesser extent, when using a hall synthesizer.
As odd as it might seem, adding synthesized ambiences actually makes just
about any recording sound /less/ reverberant.

No, he's using a box that _adds_ rear channel reverb to existing recordings.

The "reverb" you hear in the Nimbus transfers is just the natural result of
playing a recording back through a big horn.

Unfortunately not, there are enormous numbers of internal reflections.
That's why the response of a typical horn system looks like a hedgehog.

And the more broadband you try and make it, the worse it gets. Horn
systems work really well for narrow bandwidths, not so good for full
audio bandwidth.

Yes, however, the Klipsch designs have the advantage of another 20 years of
engineering, and some careful mathematics. On top of this, they are
2-way or more designs, to the bandwidth in each horn is comparatively limited
and that helps a lot. But the frequency response _is_ spiky as hell, and
those spikes move around and you move around the room.

Paul Klipsch was obsessed with the notion of getting the highest possible
efficiency from loudspeakers, because he believed that doing so would give
the lowest possible system distortion and cost by reducing the amount of
amplifier power required. In 1945, this was a very reasonable and wise
design philosophy. In 1985, however, amplifiers were a lot better and
it was no longer a good idea at all.

He also believed that if a speaker were 100% efficient it would
have a perfectly flat frequency response.

I think that that would in fact be true if the speaker also had
a perfectly flat resistive impedance to match to the amplifier output.
But getting a flat impedance would be hard!

But a perfectly flat power response need not imply a proper
spatial distribution of all frequencies.

Well, that _is_ true. If it is converting _all_ electricity to pressure
it necessarily has to have a perfect frequency response.

But it can be 99% efficient and still have a pretty dreadful response.

That's another different (but also substantial) issue.

That's also completely true, and that's really more of an issue with
modern real-world drivers than anything else.

In fact, the off-axis response problems of modern small horns used only
as HF drivers cause more sonic problems than any of the group delay issues
or compression distortion in most cases.

Well, if it were 100% efficient at every frequency... <grin>

Some people also believe that a speaker's efficiency -- in the sense of how
little it has to move to reproduce sound at a particular level -- is related
to its transient response. I don't believe that's correct.

In 1945 that was also a good generalization to make; the smaller your moving
mass is and the better the magnetic coupling is, the better the transient
response and the better the efficiency will be.

This isn't 1945 any more and now we have a lot of very different driver
configurations that we didn't have back then.

That's often the case, but not necessarily true in every situation.
Starting in the early 1990s people like Earl Geddes learned how to create a
diverse range of horn designs that were based on new solutions of the
acoustic wave equation. Up until then only a few such horn design families
had be found, and they had other limitations such as a lack of constant
directivity with frequency. Earlier Constant Directivity designs (e.g. some
designs by Keele) had used standing waves in the horn to obtain uniform
power response over their coverage pattern.

I just bought this set on your recommendation, guys, and it's great! I
would love to know what processing went into it.

It's really interesting: the announcer, who is presumably well off to the
side, sounds very hollow and comb-filtered, while the performers who are
on-axis to the horn sound remarkably clean. There is some honk in there
but by acoustic record standards it's top notch.

I'd be curious if there was an attempt at notching out modes in the horn
by the folks doing the reissue. If so, I'd assume that the modes were
different off-axis and so the notching made the announcer's voice worse
even as it made the performer's voice better. If there wasn't any attempt
at notching, then the effect is strictly the result of poor off-axis response
of the horn.

And maybe some comb-filtering due to floor bounce.

More likely wall-bounce. Most recording lathes were driven by a weight
motor which needed a four foot space beneath it for the weight to
decend. The horn could not be near the floor and any distant floor
reflection would be blocked by the performer's body.

I came across an interesting acoustic recording with real clog dancing,
which raises the interesting question of how it was recorded:

< http://www.poppyrecords.co.uk/HXP107/hxp107.htm>
Track 8

Having been a clog dancer myself, I can say that this sounds like the
geniune thing which might have to have been performed on a stone-faced
platform raised to horn height. (Believe it or not, clog dancing on the
top of a small stone pillar was a competitive sport)
