I came across this interesting video with a discussion and demonstration of 3D stereo. It actually worked pretty well on my laptop.

Although he never uses the term, it basically seems like binaural recording, which has been done for decades...

Those who do not know the experiments of an elementary school me, are doomed to repeat them. smile

Really in elementary school I read about binaural recordings (when I wasn't learning to program computers). I theorized that if binaural recordings made with mics placed a head width apart played back well on headphones, then recordings made with mics placed where the speakers were would place back well through those speakers.

Unfortunately I didn't have two mics. So I took the RCA plugs on the speakers of my mom's Soundesign and attached mono 1/8" phone plug adapters to them, and used the speakers as mics. I'm guessing (now that I have a bit more knowledge) that the "crossover" on the tweeter kept it from contributing any usable signal, but bass to midrange was recorded pretty well. Listening to the playback from a position directly between the speakers gave a pretty haunting image of people walking around the living room and mumbling.

i remember a long time ago that Sennheiser put on the market a dummy head with microphones in the ears so one could make his own binaural recordings.
no idea if it worked well though.
