i've been reading the comments on choueiri's work, many dismissive. folks who seem to know all about such things claim it's old stuff, not a breakthrough. all i know is i listend to his demonstration on my cheap laptop speakers, and could heaqr the fly buzz AROUND my head. has that really been possible before from 2 forward-facing speakers? maybe i'm missing something, but maybe the know-it-alls are so eager to shoot him down that THEY are missing something. i remember that in the 1800s, the director wanted to close the patent office, since everything had already been invented!

This seems most useful for live recordings. Most studio work is multi track sessions and often the musicians are not even playing at the same time.

Some years ago, about a decade or so, I was experimenting with surround sound offerred by the Hughes Laboratoris and someting kept tapping to my rear and I was curious just what it was. It turned out to be the realism of the Hughes surround sound. I could have sworn someone was trying to get my attention. That how utterly realistic it was.
Now, I was wondering, is this program still available?

It is great that 3D sound is on the rise. Our True 3D www.cmorrow.com has a growing installed base in Europe and North America. There is Dolby Labs atmos, A&G's systems in Italy and the numerous wave field synthesis systems.

We live in a 3d sonic environment. Everyone is 3D sonically literate. It would make sense to have a 3d sonic summit. How about sponsoring it Studio 360?

1) This method is using XTC to create binaural cues at your eardrums, and thus it is quite different from Acoustic Holography, which attempts to recreate the entire soundfield in a room.
2) Yes, XTC has been around for a long time, but Dr. Choueiri never claimed to have invented it. The problem with Schroeder's original XTC system was the spectral coloration. If you read Dr. Choueiri's paper, you'll see that it was his novel method of frequency-dependent regularization that allowed him to greatly reduce the spectral effects while still getting a large amount of crosstalk reduction.

I'm student and new to MATLAB. I need to do a project to form a program that can produce 3D sound by using MATLAB.

recently i had done the sound that moving from left to right and right to left by using ITD and IID.

But I wonder that how can I do it with the sound Moving from top to bottom and back to front？

thanks in advanced!!!

The water sounds in 3-D are terrific. Kudos to Dr. Choueiri. My first introduction to Stereo music was probably around 1969 when I listened to Iron Butterfly's In-A-Gadda-Da-Vida on my newly purchased stereo system. What a trip!

I just vividly remember hearing Led Zeppelin's "Whole Lotta Love" in stereo in 1969...and Pink Floyd's "Several species of small furry animal gathered together in a cave and grooving with a Pict" in 1970. Sounded like magic to me - fuzzy noise going from one speaker to another; footsteps chasing a fly doing similar.

And now in 3D: oh, blow your cool, man...B-)

I can remember very vividly about 1983 when my local npr station playing an spooky horror type audio play. Now Its a little foggy here. I think was based on a book. They didn't call it 3D but the sound did fill the room.At least around the radio.

I'd like to hear a piece recorded by the late and great Tony Schwartz. Sorry, don't recall what he called it, but it was a solo wind instrument in a large empty space (terminal?) with a woman in high heels walking through. It was featured in a Kitchen Sister's piece in NPR's Lost and Found Sound.

Would love to hear Beethoven's Ode to Joy in 3D

Impressive. I enjoy the discussions on technology regardless of the relative vintage of the idea or seemingly simplicity of the application, and appreciate the work any one has done in their own free time to explore something they are interested in. I would like to hear Wendy Carlos, Sonic Seasonings in 3-D.....

Hi Gary,

Another way to look at it is that many people have wrestled with the problem ever since Alan Blumlein invented stereo in the 1920's. Did you look at Edgar Choueiri's paper, "Optimal Crosstalk Cancellation for Binaural Audio with Two Loudspeakers”? He talks about the issues with past attempts at 3D sound including head-related transfer function, the Haas effect (inter-aural time difference), etc. What he does builds on these past attempts and adds another dimension (pun intended) to them.

This is really outrageous. Every 10 years or so some new genius comes along and invents binaural sound. Crosstalk cancellation has been with us since the beginning. Nor do rocket scientists have any advantage in audio reproduction. This technique cannot be used for 3D movies, because it is not suitable for large audiences; nor is it necessary, because we already have 12 channel surround sound. Please research these pieces a little better before putting them - and us - on.

Hello I just your 3d sound examples it sounded just great, I would love to hear a remix of sgt peppers in 3D sound. Will that be Happening some time in the future? thank you guy

Very impressive work of engineering.
My fully analogue system is holographic on its own through careful speaker placement and component selection. Playback of your recording was far to forward and sounded like early stereo, either on the left or right with little blending in between. These effects subdued when listened to on a less accurate system.
May I suggest that the finished filter incorporate a variable blend function from fully discrete to off. That would make the filter tunable to room set-up.
I liked your home lab.

You asked what we want to hear in 3D. I'd like to hear inside the womb--if not human, then dogs. Sounds of nature such as in forests. But I imagine the bigger demand for 3D sound will be from 'adult entertainment' industry and from the military for training recruits about the overwhelming sounds of battle. Come to think of it, history buffs might like the 3D sounds of recreated famous battles like Gettysburg or Waterloo. Myself, I'd prefer the Monty Python versions.

I still have my circa-1984 Carver receiver, but I could never get the "Acoustic Holography" function to really work.

Ambiophonics redux. Or perhaps fulfilled.

Can this technology be purchased or do you have volunteers who you use for market research etc. How does Joe Plumber get to try it out ?

Is the 3D audio significantly different from Carver Audio's Acoustic Holography? It seems much the same to me; perhaps the algorithm is different, but the idea seems the same. No?
