It has to be that the shape of the ear, relaying signals to the brain, is how we discern where sound comes from. That's why we turn our heads in the perceived direction of the sound to confirm. The recording made to duplicate hearing would have to take into account how much signal is perceived from which direction, and in what time alignment. The best way off the top of my head for this would be to take those antique RCA mics you have(well you only have one so you must get another), and configure an "ear" perceptive physical apparatus (shorten to ear-like thingy) or EPPA if you must, record, and then? Ahh, playback is hell right? Let's start by playing it back with pro logic IIx, so we will be at least sticking to some of the original theory. meanwhile, have another beer.
