Many of those classic recordings were made in 3-channel. For producing LPs, of course, only two channels were used. The center channel was mixed into the L & R channels. The SACDs can be played back as "multichannel" or "stereo".

You'd still have the time differences from L and R
Trifield, I think that's what some call it anyway, has a cult following. I've never heard it. Closest I've experienced is plain jane Pro-Logic with the rears off. Given the quality of my C channels in the past it did more harm than good. My impressions might have been very different with identical amplification and speakers to L and R.
Meridian, Lexicon, Yamaha, Citation (Harman Kardon with Logic7 derivation), Proceed, ... :b
Draw a point on a piece of paper. Now from different heights draw a line to the point. Measure those lines. They have different distances. Thus anything traveling along those lines will have different travel times. These delays in arrival times give us clues about distance, position and height.
Almost without exception, during the first decade of stereophonic recording, the engineers would opt for 3-channel recording, and would then downmix to two-channel for the lacquer-master or the tape copying master.
As Lee mentions above, we're now getting access to the 3-channel recordings through SACD (and Blu-ray), and I agree with him: they sound more realistic. The sound is simply more solid - an additional stream of sound energy is added, painting more body to the music, quite simply.
And it's also what the original developers of stereophonic recording stipulated as absolutely necessary for the illusion to work its wonders. But the limitations of technology stood in the way, as it was simply too expensive to expect people to purchase three-channel tape machines (LPs were limited to two). So, from the start, stereophonic got hobbled, and being aware of that certain high-end companies sought to still deliver a 3-channel simulation. Meridian swears by it still, with its Trifield.

Literally just found this excellent thread, by people who actually work at the coal face of recording: http://forum.recordingreview.com/f8/what-causes-height-44128/

The people in that link are not at "the coal face of recording." They are neophytes, twiddling with their garage band units in their playrooms, receiving the occasional wink from more notably knowledgeable people, such as the person writing that "this height you speak of - let me pull out a left handed cigarette for you."
Exactly what I mentioned before and started experimenting with (extensively),
and starting back in 1987-88.
As you play with the position of the center microphones in the vertical axes,
and experiment with their recording heights that can also be help by physical structures, as helpful sound techniques, and finally by adjusting the center channel speaker's height in your listening sessions, you can create anything you want. Even Height. :b
Quality microphones with the right directivity pattern, from different designs, and imaginative technics using physical structures in helping to capture the height of the recording venue, are right there at our dispositions, already.
It is only up to us to add that third center channel speaker to our front soundtage in order to recreate the full panoply of the 3D holographic soundstage in all planes; horizontal, vertical, and laterally in depth.
And then play with its own physical height (center speaker), and choose the appropriate music recording selections, or get back at it and recreate new quality and realistic recordings from real acoustical live venues with these 'magic' (great) musical performances from the best musicians, conductors, orchestras (Classical), bands (Jazz, Blues, ...) of the World.
This is hard work ...!! :b
Since Tim has been yammering for some good "technical" stuff, here is "real" material: http://www.google.com.au/url?sa=t&r...tZ3zBA&usg=AFQjCNE_qDkz1zKpmT-KubBl32Hb83VF7A
Note particularly the quite massive set of references at the end of it: appears that more than one researcher believes you can get something other than stereo ...

No, they don't. That's precisely the point. They give you clues about distance only, because that's the only thing the microphone can pick up. It has no way of discerning from what position the delayed signal is coming, unless there are two mics, one closer than the other. So left/right has clues. Up/down does not.. There is really nothing to dispute in that.
Tim
Take for example a singer like Holly Cole (Canadian Jazz female singer), and set her up standing up with the center microphone on a boom five feet from the carpeted floor.
Left and right and rear (drummer) musicians, with their mics lower for their instruments, and others at various heights for accompanying vocals, and the sense of the space on all plane axes.
Then, position your center channel speaker in a similar arrangement at home, like I said before;
about couple feet higher than its two 'flankers' (R & L loudspeakers).
Also, experiment with one, two, three, or even four subwoofers fot the full spaciousness of the recording venue; in particular from a concert hall where a classical symphonia (symphony) is playing.

Like the Boa Constrictor the more you tangle the tighter the grip. Just take that triangle you described in the horizontal plane and rotate it 90 degrees into the vertical plane...same thing, same effect.

I'm not aware of having described a triangle, but if you take the two points of stereo, of you rotate the mics 90 degrees, then rotate the speakers 90 degrees to match, you will, indeed, get a vertical image. Even on planar speakers. Otherwise, therei's nothing to rotate.
Tim
Of course. Record vertical channels and play them back through a vertical system, and you'll get a vertical image. Anybody out there have left/right high/low speakers in their system? Are you making your own recordings to take advantage of it?
Tim
Tim
Tim,
Should we also rotate ourselves?
Considering all these rotations I think that next time I will look at planar speakers I will get sea-sick!Similar threads
