Holographic imaging

If these "doppler" errors are indeed there, and are "microscopic" how does one determine where they occur, read them at each occuring stage, and how is their (I'm assuming) delicate effect, effectively corrected and how is that delicate(?) correction calibrated at each stage?
In regard to the effect of moving the listening position in a typical listening room, I would guess that the issues of the sound changing due to the change in effect the room would have, and the issues of driver intergration might swamp the effect of such "doppler" issues.

"then an amplifier should sound "flat", because that is closer to the truth"

You lost me on this. Why do you think "flat" is closer to "the truth"?

What "truth" are you referring to?

Musicians perform and sound waves propagate in 3 dimensions last time I checked?

Not that "holographic" necessarily equates to truth either, but I can't see how "flat" could be closer to the real truth either.

Your not just yanking our chains for fun, are you?

"Not that "holographic" necessarily equates to truth either, but I can't see how "flat" could be closer to the real truth either."

Actually I can think of a way. That would be assuming "flat" refers to a projection of the original 3-D sound onto a flat plane, much as portions of the real earth are projected onto paper maps.

In this case, realize that projected representations of 3-d objects onto a map are inherently and by design distorted reproductions of the real thing.
