When I do such a test with my SASS, using headphones, I get a really nice
180 degree depiction, the only weakness being that front and center sounds
like it's coming from above.
As I go around behind the mike, mostly it sounds as if I've turned around
and proceeded back in front of the mike. This is typical of all binaural
setups, unless they're tweaked for individuals. Even then, rear sounds often
are projected toward the front.
This is one reason that I've decided to use my SASS recordings primarily for
180 degree frontal playback (with some convincing 3D or height effect). This
can be simply accomplished using two conventional full-range speakers, each
placed out to the side (as I've described previously). One clear advantage
of using speakers is that sound sources originating front and center come
through sounding like they're front and center, as opposed to headphones
which often render them overhead center.
While a lot of research is being done that could eventually extract a full
360 degree arc from two tracks (possibly including lots of 3D or height
effects), it is much more reasonable at this time to investigate ways to use
4-track recording to produce an encompassing playback soundstage.
