Uhm...yes...it is obvious and well known, that in many cases (though not all) the imaging and soundstaging is an artificial creation. And of course the image/soundstage of the real event would be different for listeners on either side of the musicians.
All obvious.
The curious thing is you keep using a term "holography" when we already have terms that refer to these effects in stereo playback: Soundstaging. Imaging. Any decent stereo system will reproduce the encoded soundstage/imaging artifacts of the source.
Yet you keep using the term as if to refer to SOMETHING DIFFERENT or BEYOND the soundstaging and imaging most of us hear.
Why don’t you just ask people if soundstaging/imaging is important to enjoying their systems? Why introduce a distinction...with no distinction...that only confuses things?
I was listening to some Gordon Lightfoot recently. His voice appeared floating between my speakers, with a sense of 3 dimensionality and body, very reminiscent of a real person who may have been sitting between the speakers.
That’s imaging.
What is different about that, vs the "holography" you are talking about?
