I'm hoping to get one of these printed for me soon . . . . (But in BLUE . . . colour is SO important in these situations? :lol: )

Check out the video.

I think the positional info generated is amazing . . . . .

Interesting :D

Focus of sound followed the turning camera ........ just like our ears .......
but ... would it not be the same result using two directional microphones ?
Cool gadget though. ((i))

Hi Peter,

Binaural is rather a special case. Sadly, it only REALLY works WELL with headphones - not to say the sound isn't "ok" with speakers, but it is really a headphone system, as this is where the positional detail is at its best.

The main proviso for complete satisfaction - is that you DON'T move your head. If you rotate your head, the entire stereo field rotates with it - which spoils the effect.

IIRC, Sennheiser pioneered the system called "Dummy Head Recording" back in the 70s, and actually produced and sold a "Dummy Head" with mikes built in to achieve this.

The device I mentioned, and hope to have "printed" is merely a minimalist version . . .

Interest in the concept largely died, though I believe Edgar Froece did an album using the technique, and the BBC also did broadcast a "Play without voices" in binaural - which was entirely a sound pastiche with NO recognisable dialog - called "The Revenge" IIRC . . . .

The generally accepted method for recording stereo from a single position is with a crossed-pair of mikes:

in this arrangement, the right hand mike is recording the LEFT channel :lol:

It IS possible to widen the mike spacing, but care has to be taken to avoid the "hole in the middle" that you tend to get ...

This is usually solved using a Decca-Tree arrangement. Mostly used for orchestras or larger groups of players, it is placed higher up than normal, and in addition to Left and Right Mics, uses a third mike for the centre (to fill the "hole"). More mikes can be used for special purposes as shown here: http://www.mixonline.com/news/profiles/ ... ree/365206

This is the 7" demo that Sennheiser put out in the 70s.

Although it's promoting their "Open Ear" headphones, it is a "Dummy Head" recording. Indeed, the best effect is said to be obtained using Open Ear Headphones.

Here's a pretty good one. (Y)



When using headphones, it's still only two speakers and two ears, but you do get the "feel" of the room.

Here's a shot at 3d sound from Yamaha.

That was really weird watching on the phone with my in-ear phones. The sound was all behind me, even though it kinda moved in the right direction. Like if my ears were 10 meters behind me! :lol:

Less weird in the studio cans, but IMHO it sounds 'too close' in lack of better words.
I guess the weirdness listening with the in-ear phones comes from the speaker elements actually being much closer to the ear-drum than the ones in the studio cans.

I suspect that I'm expecting more reverb and therefore think it sounds too close... dunno.

Cool stuff regardless! (Y)
