I liked it way back when it was called stereo.

it's absolutely not simply stereo. It's called holophonic sound. And it requieres 2 separate microphones to capture the sound, at approximately the same distance from one another as the ears are on a head.

Try this one as well. It has the virtual haircut which is awesome. If you close your eyes, it's like you're almost there... http://www.youtube.com/watch?v=8IXm6SuUigI

also, I wish they could use this on videogames. it would make for a much better experience

Two separate channels are being played back, yes? That's called stereo. I've recorded with this technique before and while the *recording* methodology is slightly different...the *playback* is good ol' stereo. I'm not knocking it, I'm just saying: this is stereo.

True story: in 2002, I purchased a pair of tiny clip-on condenser mics with a portable power supply for the purpose of capturing sound effects in NYC. I clipped these two mics to either side of a baseball cap I was wearing, making sure the distance from each other was the approx distance between my two ears (just like Empire said). So I walked from our hotel (the Millennium on 44th and B-way) all the way down to ground zero, recording all the while to a MiniDisc recorder. It was quite a haul.

On the way back, I walked through Washington Square Park, where I was approached by a drug dealer who could tell I didn't belong there. He said to me, "you buyin'?" I said, "no, not today. I'm working." Then he notices the mics clipped to my hat. They're small but they're not invisible. He gets this solemn look on his face and says, "You a cop?" I laughed and said "No, I'm recording sound effects." Then he gets genuinely worried, asking "You recording me right now?" I said simply, "I'm afraid so." He turned right around and walked away. Sprinted, more like.

Then I ducked into the nearby restroom to check to see if my MD was still going and, lo and behold...it had stopped: our encounter was not recorded. DAMN!

But I did get quite valuable street sounds: buses, cars, people shouting, talking, all the sounds you'd expect to hear in NYC. And it was all recorded using this method. The stereo playback sounds exactly as though you're there.

2-speaker 3D sound in video games is far beyond this technique. This technique is great for video, but I don't see how it applies to video games really.

Video games do tricks with 2 speakers like adjusting the tone of invdividual sounds in the environment based on their orientation and elevation relative to your ears (AKA the mic) within the game scene. A good 2D sound engine is basically creating a holophonic sound mix in real time.

Too bad my bone conduction analog hearing aid only hears mono to enjoy the directional audio. However, I do love feeling bass (not the fish )!

They do and have for years, it's called EAX.

holophonic sound has been in use for at least a decade if not longer. I've made some holophonic recordings for my films and CDs, but it's been a challenge finding venues with the 7.1 systems in which is most effective.
