What are the best available products (microphone or array of microphones) available for highly directional sound recording in 3D? Can you convert them for 7.1 encoding? Anyone else would love to have such products?

Can I start? There's that word "best" again. Is there a best anything? What is the best music?

What is 3 d recording? If it must be converted to 7.1 how are you able to achieve it otherwise? I imagine you would need at least 4 speakers to create any sort of dimensional image. Ideally, I would think you'd need at least 16. Two front, four side, two rear, four in the ceiling and four in the floor. That's a 16 channel speaker system for a basic three dimensional sound. Even then, you wouldn't really be able to portray distance in the space directly surrounding you. Only the distance that exists from the walls and beyond. It would be "3d" but you'd still feel like you're in a bubble.

Anyone care to burst my bubble on this one? Am I way off?

I think I was not specific enough. Let me rephrase the question.

Suppose there is a microphone which is capable of recording from all directions in 3D then electronically separate and record sounds from distinct directions. For example, say there are 3 musical instruments at 3 different angles and some noise coming from a air-conditioner somewhere from the roof. This microphone should be able to record/separate 3 musical sources separately while eliminating noise from air con.

My Questions are
(i) have you known of any such microphone/system
(ii) Does such a microphone/system have any use for you?

Hmmmm....
Every recording I make is 3 dimensional.

Afterall, time is in fact a dimension. Width and Depth aren't a problem.

Discrete mic'ing of instruments is nothing new. Doing it from within a single mic isn't terribly new (as Boz points out.) The problem with the situation that you're describing is one with physics, not with mic'ing. You see, if there's an AC making noise at some single point within a room, the sound propogates throughout the room and fills all of the space in the room. Therefore, your other mics will pick up the sound of the AC regardless of which direction they're pointed.

There's a lot of information on discrete mic'ing - poke around here and you'll see a lot about it.
