Yes, if the playback is supposed to sound like that instrument IN THE ROOM WHERE
PLAYBACK OCCURS. But that isn't usually what we're interested in.


Your argument seems to be that transfering the instrument and the
original room into the listening room is possible because the direct
sound from the speakers dominates the listening experience. I
actually don't disagree with this.

I would not even disagree that the goal of verbatim reproduction
*should* ideally be to superimpose the original room onto the (given)
listening room. Just never been very convinced by any I've heard. Yet!


Verbatim reproduction is a false god?


It's the right god, but few people want to worship.


The alternative god, that the emotional content is a separate thing
to be captured, is also very seductive. I wonder how much they really
conflict? Lots still to learn, for me.

But, all of this really is irrelevant. The point that the original

poster
was making is that the whole process of recording and reproduction
exists to produce an illusion. You're just arguing about the accuracy
of that illusion. Either way it's not a real orchestra behind there,

it's a
simulation, and that simulation only varies in degree.


I hate to jump on you for this, Scott, but such a view is just a lame

excuse for
producing lousy-sounding recordings. See the interview with the world's

leading
recording "experts" in the current Abso!ute Sound. They don't know what

the hell
they're talking about. It's pathetic.


Blah, blah, blah... As I said. Recordings lie.

We choose which lie we like the most and go with it. Some may be better
than others, but there is no way that a microphone and a speaker can
reproduce sound the way that our ear hears it. Ears are pretty amazing
things if you think about it. The way that they can pick up faint sound and
perceive directionality is pretty amazing. Speakers give us an
approximation, but it ain't the real thing. Period.

What I'm really saying, though, is that since no speaker (reproduction) sounds
convincingly like an instrument (production), maybe we should concentrate on
making recordings we like the sound of & not be overly concerned that we
haven't achieved verisimilitude, which I maintain isn't achievable anyway.



It IS achievable, with existing technology.


No it isn't and not even approximately. First it could only
possibly work in the original room with nothing in it
having moved and even then it can't because there is
absolutely no way within the realm of the possible to
recreate the exact time varying pressure field at every
point in a room that existed there when generated in a
different way than by a loudspeaker. Too damn much
information by an enormous margin. Enormous isn't a big
enough word. All of that is required for versimilitude.

Plausible illusion is all that is possible and I doubt
anyone will complain if they are hearing something
believable and appropriate whether it is accurate or not.

And I will say that what we need is a way to totally reproduce the
three-dimensional wavefront coming from all directions toward the listener,
so that the actual pressure at any point in your room is exactly equivalent
to the pressure at that point in the section of the original room around the
listener. Until that happens (and it's going to happen someday), we don't
even have a very good approximation.

I'm sorry, but you're wrong.

If you would set up a W/X/Y Ambisonic array with really good mics, and play it
back through first-rate speakers, you'd be startled.

It is possible to come pretty damned close, in playback, to what you heard live.

How can that happen? The sound of the listening room will be
superimposed on the recording, unless you're suggesting anechoic living
rooms.

It is the difference between bringing you to the performance, and bringing
the
peformance to you.
The former requires an acoustically dead recording, while the latter requires
correctly recording and reproducing the original ambience. Totally different.


Someday you'll have to explain how you're seeing these as unrelated, because
I'm hearing you describe two variations of one activity. Somewhere we're
missing each other semantically.

Go out and make a B-format Ambisonic recording, as I've suggested (and have
done
myself), then come back and we'll talk.


Fine, but that B Format recording has to play back through speakers, & that's
where the illusion utterly fails to convince. A violin in the room & speakers
playing that same violin performance simply are not going to be plausibly
interchangeable. The problem is not in obtaining a reasonable recording. The
problem is in transducing that recording.

Why would you want something devilered to you, George?

BYW George, the problem is probably not the wires, magnets, and paper, but
rather trying out what to do with them. AFAIK in terms of total realism,
we're already screwed by the time the audio signal hits the output terminals
of the mic.

However, in the end music is about emotion, not sound waves accurately
impinging on our ear drums. At times I can get the same emotional experience
as live listening, from even fairly medocre reproduction of a modest
recording. To me, the emotion is primarily in the playing and the music.
Good reproduction just sometimes makes it easier. OTOH, if you're not in the
mood...

but we are not talking about haveing a enjoyable experiance
the way I read this thread is one camp is saying that they can deliver
the exact same aural fingerprint of a acoustic instrument through a
recording, I say it will never happen
not that we can't feel the excitment but one can not recreate the tone
of a instrument , not even remotly, in a recording

But what if the playback sounds like the original venue?

It won't.


There's something wrong
with that?


So you're distinguishing between a recording of an instrument & a recording of
an instrument in an ambient space? Is this the crux of what I'm not getting
about your contention?


Yes, that's exactly the point.

What is so confusing about this? As I said, the issue has been around as long as
we've had commercial recording.

Modern (ie, electrical) recordings are almost always made "live" -- that is,
they contain some sort of ambience -- either "natural" or synthetic -- that is
either supposed to represent the original venue, or simply sound pleasing. In
this sense, the listener is "brought to" the venue.

To put it the other way 'round, the listening room is not supposed to make a
significant ambient contribution to the playback.

you must have a very low regard for the actual sounds of acoustic
instrument to claim the experiznce of hearing one live can be fully
duplicated with a recording


First of all, I didn't make such a claim. I claimed that you could come
pretty
damned close, with existing technology. I stand by that statement.


not even remotly close IMO.

another matter.


I just don't know what to say to that. If you find anything
with what I've said incorrect in a technical sense how about
addressing it in a specific technical fashion instead of this
"you're wrong, I know better" stuff. You've said nothing
so far which indicates that you have a clue.

By the way, Bob -- You've never said whether you've actually made recordings, of
any sort.


I think I've stated the answer to that in numerous ways in
the past. Yes I have, of many sorts.

No, I asked you, who claimed to know it. If it is correct,

One of the reasons I have long been a supporter of Ambisonics is that it
resolves the conflict between simple miking and multi-miking -- you can make a
single-point recording that is free of the psychoacoustic artifacts that plague
conventional single-point recording.


It's different all right. Care to be more technically specific about
those psychoacoustic artifacts?

Simply because I've done both live and studio for almost 30 years, and
I know you're heavy into the reinforcement side, I think what these guys
are getting at (given both specific recording *and* playback parameters
are met) is not entirely impossible. At least they have the faith (desire)
to believe they'll one day prove it's possible. I doubt their faith will cloud
their reasoning... too much... g
