Dear Dr. Choueiri,

I have written a novel entitled Burden of Privilege:The Secret Life of Geoffrey Collins. I am working to have it adapted as a motion picture. It will have several experiences for the audience that have never been done before visually or aurally. I have heard you are working with James Cameron on Avatar 2, 3. B of P will have visual and audio effects that will not even be found in Avatar (unless the script creates a reason for it and then I'm sure you'll make it happen). I know you are very much in demand but if you would ever take the time to speak with me, I would only ask 3 minutes of your time and would be glad to share what I believe is a revolutionary embellishment to your already existing 3D sound technology. It would involve the audience as never before. Please indulge me for a few notes of trivia: I was born in Trenton, NJ. My father saw Albert Einstein mowing his lawn in the 40's while driving to work one day through Princeton. I am also an environmental visual artist that has always been interested in earth related science, and am also a musician of sorts. If you wish to preview my novel, a synopsis can be found at www.sheppardpublishing.com It would be such an honor to hear from you.

Very realistic...it gave me the willies. I like brooding cellos...I'd love to hear something like that done with 3D audio.

WOW!!!!, just like BINAURAL!!!!!
May be in a couple of years , They will invent Holophonics Tm, that has been around for 32 years already.....LOL.

There's another Edgar who pioneered sound-moving-in-space: Edgar Varese.

Also, one of the spatial cues for sound moving behind the head is caused by phase cancellation at around 8kHz that occurs by the way the sound reflects off of the structure of the external ear.
The comment above, "Good stereo recording techniques will create great stereo." is dead-on.
Because the listening environment affects the final delivery, unless everyone has an anechoic chamber, driver placement that is exact to the millimeter, and something to hold the listener's head in a fixed position, there will always be a trade off between imaging width and depth and "wandering" images at some frequency ranges.

It sems a dream, but it's a real site to
enrich the enternet. I'm adoring it!

Amazing technology! It truly makes a difference, even on my crappy PC speakers. But in what way is this different from QSound technology? Their online demo's kinda offer the same wider-than-your-speakers stereo experience.
Hopefully your iTunes filter becomes available to the general public soon, would love to try it on some old but well recorded piece of music.

I am a young aspiring audio engineer, musician and student. I would love more than anything to have the ability to use this in my work and I would like to thank Edgar Choueiri for doing mankind such a service.

I "Stumbled" upon this link a couple of months ago:
http://www.youtube.com/watch?v=uzFswCpJPqg&feature=player_embedded#at=68
Which seems to have a very effective way of fooling at least MY brain into believing that it is hearing in three dimensions... with headphones. Very interesting technology.

What music or sound do you want to hear in 3D? Leave a comment and let us know.

Answer: The Classic Rock albums I grew up with. Beatles, Stones etc.

http://www.calgary-city-maps.com/classic-rock-official-website.html

I've been "constructing" timbral compositions in binaural space for years, using the MIT HTRF library. Each mono track is processed through a convolver and a specific position sample from the MIT library. In this way, all positioning information is obtained through a set of HRTF samples, rather than through the un-natural "pan" control -- in other words, the pan is centered for all 8 tracks. But the experience (on headphones only, of course) is of a startlingly realistic spatial environment. I've also experimented with 8 speakers in an octagon, but the tiniest movements of the listener's head result in extreme phase effects, unless the octagon is at least 10-20 feet in diameter. I'm skeptical of a speaker-based system that can provide the required exclusivity to the sound for each ear without also drastically restricting the listening position. I have a few assembled binaural recordings at http://timbreProductions.com that can be downloaded for headphones.

About 15 years ago, I saw a movie where they were testing / demoing a system where you rented a headset with a pair of built-in "directional" speakers, which did an _amazing_ job of 3D sound. The headset sat on your head, a bit like a crown, and the pre-movie demo of the technology was more than worth the cost of the headset rental. People were turning around to look for the source of some of the sounds, despite knowing intellectually that it was a demo.

I've never seen that system again, and I don't know what it was called, but it was amazing.

This page is astonishing. Prof. Choueiri presents his work as his own original research but his work is no different than other work that has been done by others in the last 25 years. Indeed, Manfred Schroeder did work in this field in 1961! Schroeder's work was improved upon by others in the 1980s and 1990s and Choueiri's recordings sound no different. It is amazing that he can get this much traction from a press that is asleep at the wheel. To present this work as new and original is raw academic dishonesty. Let's hope his reputation in plasma physics remains intact.

when is this filter to become available to broadcasters, and where do we find it

It'd be awesome if one could hear the music of Hans Zimmer, John Williams, or Michael Giacchino in 3D, this is the future of audio, right here!

Crosstalk cancellation is a well-known process. Dr. Choueiri's technique is a very smartly done version of it.

As Ty Ford noted, the sound sample you provided plays back in wide stereo, with a notable hole in the middle. There's no sound that comes from direct left or right, none from behind, and none from above or below.

Using headphones, one can do better with simple binaural recordings, and much better by adding head tracking.

To do better over speakers you'd need more than two speakers. Probably the best way to get good 360-degree (in azimuth/horizontal) playback requires 6 speakers arranged ina ring around the listener, and an Ambisonic decoder.

I would like to draw the attention of all concerned to the work of a prior worker in the field, A. Klayman, who designed the Hughes AK-100, an astonishing unit! Let us remember those who went before and paved the way...

The naming of "3D" to audio is not very good. 3D movies pop out of the screen at the viewer. This audio sample does not do that. Instead, it goes wide. That's not 3D. So what we have here is a marketing misnomer used, presumably, because 3D is a "hot" marketing word right now.

This sound is very similar to sound processed by the Bedini Audio Spatial Environment hardware box that I reviewed professionally for Radio World or Pro Audio Review in 1991. Here's more on it: http://www.bedini.com/base.htm

This is an absolutely amazing step forward for binaural audio. Hats off and high fives to Dr. Choueiri from everyone at Kall Binaural Audio here in Halifax!

I too came here looking for information on a 3D plugin for iTunes. Will this be available soon??

That gurgling water really made me have to go to the bathroom.

olivier messiaen's quartet for the end of time, holst's the planets, and miles davis' kind of blue seem pretty obvious to me as things i'd like to hear in 3-D.

I am also involved with 3D audio technology which was done in collaboration with Weiss Electronics

I can play any CD (including mix CDs made on your PC) and present them in a 3D format on relatively inexpensive equipment (though it does sound better on better speakers at least).

Actually it can also make an Ipod sound great but the source needs to be up-sampled to be processed by Maya.

http://mayaacoustics.web.officelive.com/default.aspx

We are in early stages of commercialization and it compares favorably to the samples I have heard here or on Astoundsound

I would be happy to demo this in Santa Monica, CA

all good and interesting, but the 11 year old's recording is what really got me.

Finally got to hear your 3D sound episode, downloaded it in iTunes and skipped to the section.  As a sound designer for my independently released Modular Synthesizer music, I am extremely interested in experimenting with these filters to see how effective and ineffective parts and aspects of my music will sound using this technology.  In addition, as a Live Sound Engineer I am interested in the affect this could have on a live theater show in increasing the realism of a performance.  When listening to the birds and the stream, the directionality is crisp.  This crispness seems to deminish with the addition of reverb, as in the Bach piece.  I almost think the Bach in 3D would be more effective dry.  Thanks for the good stuff.

Amazing! I would love to see this work it's way into everyday applications. TV, radio and computing.

Sounds to me as if there's a lot of out-of-phase information there. The soundstage extends out beyond the speakers on either side, but there is a pronounced hole in the middle.

Remember that most recordings are mixed on speakers in a studio. Those studio speakers have crosstalk, just like the speakers in your living room. When the engineer mixes the recording, he (consciously or unconsciously) takes into account that speaker crosstalk in adjusting the mix. When the engineer is done, the recording, played back on *speakers* (with crosstalk) sounds the way the engineer, producer, and artists intend it to sound. When you play it back on your living room speakers (assuming they're decent speakers), it will still sound the way the mixing engineer intended. After applying Choueiri’s "filter" the playback will no longer sound the way the artists, producer, and engineer want it to sound.

So if you want something that sounds *different* from what the artists intended, by all means go for this technique. If you don't mind extreme separation with a "hole in the middle," by all means go for this technique.

Keep in mind, engineers have been working hard to get the "sound stage" to be as realistic as possible. They could have done this "phase alteration" trick years ago... others have played with phase alteration long ago, have noted the problems created (like the "hole in the middle") and have decided not to use it. The engineers, producers, musicians apparently did *not* think this was the most realistic option. And I agree.

I would love to hear:
1) sounds of the natural outdoors world (forests with birds, the seashore with gulls, etc.) but also of cities and manmade sounds from around the world e.g. traffic, trains, the space shuttle takeoff etc.
2) Evocative Music e.g. Debussy's La Mer, or R. Strauss's Ein Heldenleben

After listening to your broadcast, I have memories of hearing :Dark Side of the Moon: and Quadaphenia: and wanting more... True 3d in 2d is a studio trick if you know it. and transforming stereo into 3d really can be achieved with traditional layering of studio sound.,

location b bleed is limited by the capabilities of the sound....and those who can hear it.

If this can really do it through a mathematical plugin, it changes everything. I want it and if it is so transforming, I want it for free... then see who can make be best of it and still make it sound good in regular stereo...

left, right, center are defined. the difference in between make the sound you hear.

I would love to hear the crowd at some sort of game. Basketball would be good because there is court noise to hear.

Other things to hear would be:

a gunshot with sound bouncing off buildings nearby buildings.

Several people talking at once as at a party, can we discriminate and focus on one as we can in real life?

Can the laugh track of a show be put out with you, the listener, while the show goes on in front of you, with only two speakers?

This is very exciting.

The idea is very interesting, it definitely does add feel of space for the soundscape effects like water or forest.

However for music, specifically the Money by Pink Floyd, it doesn't sound that impressive compared to the surround mix of the same album.
The demo of Money does sound like the channels are being put a little out of phase (something that any good sound editor program can do, they sometimes call it narrowing or widening the audio panorama), which makes center weaker and makes sides stronger - exactly what one can hear in the demo. I am sure that the plug in does more than that, but this is how it sounds on a fairly well calibrated system.
It is also worth noting that song Money was mixed for the regular 2-speaker systems, so ultimately any "surround" information was already removed by the sound engineer.

However there is an amazing mix of Dark Side of the Moon in 5.1 sound, it does have all the spatial information and it does sound amazing on the well calibrated system. It would be very interesting to hear the result if the plug in could be modified to take a 5.1 sound mix and play in on a 2 speaker system while maintaining the spatial information of the sound - that would open up a lot of possibilities for those who enjoy surround sound, but do not have a space and money for a proper installation of 5.1 system.

OUTSTANDING! These sounds added to the 3D films would be amazing!

I write opera. I use a synthetic voice patch when I compose, as an aid in writing for voice. I would like to be able to write for Virtual Opera, 3D digital. One of the main obstacles, is a voice patch for chorus! It would be wonderful to be able to have a patch that could handle words -- a singing voice patch. Such patches exist, and, I believe, exist for several voices. I do not think they exist for chorus.

I am most impressed with Edgar's work, but then a person who works with rocket engines, creates a new sound experience and immigrates from Lebanon, it would have to be an Edgar kind of person. I give him 2 years tops and he will find a way to have his 3D sound affect the Olfactory nerves so one will be able to smell the piece as well. Can't stop there, then it's on to sence of taste. Doesn't take much effort when you listen to his demos that one can almost see the piece as well with your eyes closed. What's left - the sence of feeling. Oh, Edgar, what have you done? I also see in 2 years, better, cheaper and simplified audio systems with his technology making everything we use now to listen to recorded things on as obsolete as the 8 tracks; remember them? Get me a job working with you in Princeton Edgar.

Mahler's Second or Eighth Symphony, and Wim Wenders' 3D documentary on Pina Bausch, PINA!

Pink Floyd's Dark Side of the Moon would be a very good choice. In fact the band deliberately presented that work as a 3-D experience. In the spring of 1973 I witnessed a full performance of Dark Side at (of all places) a hockey rink in Madison, Wisconsin. Speakers were place front and back, left and right, and the music was mixed in dynamic Quadrophonic sound. From my vantage point in the middle of the floor, just in front of the mixing board, guitar sounds swirled overhead, as red and green lines of laser light danced through the smoke filled space. Pink Floyd were truly rocket scientists, taking their audience on a visual and aural trip!

I am a musician, broadcast television engineer and systems design engineer for many years.

I remember going to the NAB convention (Nat'l Association of Broadcaster's Convention ) in Las Vegas back in the nineteen-eighties..

I picked up a CD touting "Dimensionality" for stereo processing.

While wearing headphones, the developers had created many interesting effects including things like an approaching helicopter beginning behind your head and gradually flying over and away in front. The effect was startling to say the least.

I believe they were using 'phase-correlation or cancellation-filtering to achieve the effect. It was remarkable but was perceived as a 'gimmick' and nobody adopted it.

Your technology is exciting. I cannot wait to hear a full-length musical concert to experience it.

Respectfully,

Nicholas Chase - producer / director / engineer / writer etc.....

I want everything on my library! I can't wait for an iOS app and iTunes plugin!
Anything from Bonobo, Zuco 104 or Koop!

Strauss' Zarathustra would be awesome.

Finally! Realistic reproduction of music. Let's hear a large pipe organ recording and, please, get this technology out to the masses ASAP.

Superb Edgar, I know rocket scientists who could never realize a final product, this has caught my attention. Please become successful and simplify our ridiculous over investment in more speakers is better attitude. I would like to see this in hospitals as therapy for those who cannot get out to hear the world outside, keep up the good work, I trust from your choices you have already made, your decision on what we will hear next will be equally considered.

Being an acoustic physicist myself, and conducting my own R&D in the field of psychoacoustics for over 23 years straight here is a real opinion: Edgar's work is fantastic for academic purposes and introducing students at Princeton to the fundamentals of psychoacoustics and what we typically refer to as "sound localization". Klaus Genuit with Head Acoustics in Germany, Bill Gardner with the KEMAR dummy head from MIT Media Labs among others have all gone down this path. and there is always room for improvement. For any real-world applications, unfortunately binaural dummy head "recordings" not a post production audio DSP solution capable of "processing" (not recording) any input mono or stereo audio to 2 channel out, are simply not compatible with workflow integration say for film mixing at a dub stage, and they most certainly, regardless of whatever compensatory audio DSP is completed AFTER the localization cue recording, will not pass QC testing nor will the localization hold true for the standard fold-down that is always done to create a two channel from a 5.1 audio mix session (commonly referred to as an LTRT for the Dolby 2 channel encode that decodes to LCRS for Pro Logis, or a stereo ITU fold-down). For any professional audio production work, not academic, this is the area that I have focused my life's research on, and we have complete workflow integration, have passed all QC testing at the largest film studios such as 20th Century Fox, and most importantly, all of our audio stays in phase, with negligible tonal colorization, and zero rolloff for what is called "mono compatibility" testing as is required by all dub stages or any post production work at any studio that knows what they are doing. So, having said that, please understand that what Edgar is doing could potentially one day be something where he could sell sound effect libraries for smaller independent studios to utilize for thier projects, however, this will take a VERY long time before he is ready to do that as all of his sound effects that he records will have to pass all QC testing, or it will get kicked off the dub stage, and although he corrects for phase, this causes a rolloff, and thus you will lose mono compatibility (usually for binaural dummy head recordings this happens in the upper frequencies, however, it really depends on several factors leading up to the phase issue in the first place). If you would like to learn about the R&D that I have been doing concurrently with years of software development, please check out my recent interview with one of the leading Pro Audio and Audiophile AV writers, Scott Wilkinson, at http://www.ultimateavmag.com/content/podcast-58-jerry-mahabub and you might better understand why we as humans perceive elevation azimuth and distance cues, and it takes a lot more than a dummy head and some corrective filtering...

I don't know, but I don't hear any amazing 3D sound with headphones. I have heared much better examples of 3D sound, like the one from Aimar: http://www.youtube.com/watch?v=WYdIidUIbAs

We need this now. This is like showing us DSL and then expecting us to go back to dialup. I can't enjoy music anymore. Not now that I know we haven't been listening to a "clean" sound quality. The difference between 5.1 and this is staggering. Those that compared the two and pointed out their similarities must process sound waves much differently that I do because its night and day to me. I'm not really interested in listening to anything now unless its 3Dified. Godspeed to marketing. Sooner I can listen to music again.

Donald fagen; 'Walk Between the Raindrops'

I would like to make a thesis work of this topic... I really like acoustic and sounds... what do you recommend me... or how can I begin on this field???

My dream is to hear Wagner's entire "Ring" in 3D sound. What an incredible experience that would be!

Edgar, you deserve to receive the Nobel prize.

I believe I'm following the mechanism - sort of a phase cancellation similar to noise reduction headphones, but applied to only cancel the portion shared by both stereo speakers?

I'd like to request a music piece by SONOS called "Come Here Boy", very rich a cappella with varying mic distances, dynamic vocal range, solo and choral stereo blending, and electronic voice processing. It's on the album called Sonosings. Thanks very much. I'd like to know more about this process.

Have you tried anything along the lines of 'binaurual beats'?

http://en.wikipedia.org/wiki/Binaural_beats

Edgar's invention is the answer to all those "what if someone could...." questions. This 3D sound is my dream come true!! Please let me know when this could be obtained commercially.
Mr. Choueiri, not only you honor all those of Lebanese descent, you honour us all. Thank you!!

This plugin for iTunes should be made available on iTunes... I would love to purchase it! I figure $19.95... hell, I'd purchase it if it was $129.95! Great job and congrats!

I'd love to hear fireworks and Philip Glass in 3D - any composition would do but Knee Play 3 from Einstein on the Beach would be my first choice.
Also, the headline for the show tricked me...I thought I was going to hear Werner Herzog in 3D. You planted a seed there; a 3D Herzog monologue would be awesome.

I'd like to hear the great orchestral classics like Beethoven's symphonies, Smetna, Hayden, Brahms, Tchaikovsky, etc. What a rich experience that would be.

@Deb from Cambridge: Yes, I think that's the idea.

Oops, I meant to say "from the speaker of the other ear?"

Can someone explain this separation thing for me? How is this different from headphones, where we can't hear anything in one ear that comes from the speaker of the ear?

Wonderfully shimmering effect! That's the wettest water I've ever heard -- sensational, and such a tactile, remarkably defined audio experience. Thanks!

"Trippy enough?" Brother, 3D sound is an *incentive* to get high. I'm sparking up right now.

Brilliant... Please make anything from my Bloody Valentine's Loveless into 3D sound.

I'd love to hear fireworks and Philip Glass in 3D - any composition would do but Knee Play 3 from Einstein on the Beach would be my first choice.

I was eagerly listening to the story in hopes that this would finally let me understand why people were so excited about stereo sound all these years. And, as with everything before, it utterly failed me. The segment of the birds continued to sound as flat as ever. I have to wonder how many others like me don't experience this.

Two words...RADIO LAB!

How does this differ from ambiophonics and binaural recordings? I have a binaural CD that's nearly twenty years old.

How about shutting up for a few seconds so we can actually *hear* the bloody thing?

@Barry_NJ re: Ambiophonics. I was exploring Edgar Choueiri's research website on 3-D audio at Princeton and came across a FAQ that responds exactly to your question:

http://www.princeton.edu/3D3A/PureStereo/Pure_Stereose17.html#x39-1700017

Basically, Ambiophonics relies on a different speaker setup, is un-optimized for crosstalk cancellation, less realistic, more computationally intensive, etc.

I've spent considerable amounts of $$ (digital crossover, room equilizer, ribbon speakers, tri-amped speaker system) trying to improve the depth and width of my stereo soundstage, so I was very impressed by your listening samples. When can I purchase this 3d sound enhancement?

It would be nice if I could play the demos through my iPad.

Great! I have been working along these lines to apply it to lower budget film making, theater and audio sound track recording. Except for a few people who are working on meager budgets, the "Audophile" engineers who constantly guard the patents drive the costs of the recording software and hardware up to the stratosphere so that it never gets applied. This will be wonderful for Internet Sound but not if it sits on the shelf at Princeton or is only applicable to Spielberg or Lucas.

Parameters of crosstalk cancellation is depending the speaker positioning, room acoustic, the listener head and ear (HRTF). Hard (impossible) to imagine one setting for all listening situation.

Crosstalk cancelling is cool way to achieve better sounding consumer listening. My way is the 3D recording with new mic physics and configuration.

PLEEZE .. people have been monkeying with stereo since Edison. Good stereo recording techniques will create great stereo. Unfortunately great audio has taken a back seat in the past decades except in very narrow niches. This leaves an opening for "new" techniques and revelations.
The problem in general with manipulations that focus phase & sound in SPEAKERS, is that it creates a stereo sweet spot that only works in limited instances. For much greater control we already have 5.1, which is widely available, has wider sweet spot, can be compatible with music and movies and RETAINS the original artist choices as far as sound placement is concerned. So lets use what we've got to better sound reproduction. When SOME record company or independent starts issuing 5.1 audio only (mostly) DVDs we will have a new ball game.... product to sell, that is harder to down load, AND sounds better.
Listen to the 5.1 of Roxy Music Avalon.. brilliant.

I don't know what moved you to change your website but I can't figure out why it is better. KQED doesn't play your program any more so I can only get in on the website but it is very confusing.

How is this different from what Ralph Glasgal developed years ago, it's called Ambiophonics...

http://ambiophonics.org/

and

http://en.wikipedia.org/wiki/Ambiophonics

This is amazing! I can't wait for this to be available! Honestly I feel that 3D film is overrated and a Fad, But the listening experience that this filter could offer could change it all! Thanks for the great story!

The only market for 3D Sound will be as an add-on device. You will have to add it to every TV, receiver, MP3 player etc. that you want to hear the effect through.

3D Sound does indeed give a pleasant sense of spaciousness, similar to Bob Carver's Sonic Holography. But as a recording engineer, I also recognize the effect as being similar to what happens when a spaced array of microphones is used to capture a sound stage without paying proper attention to cancellation issues: very spacious sound, but with poor mono summing. The enhanced stereo sound stage collapses into a relatively puny mono. This is not a concern for normal home listening, but radio, movies and TV will not be quick to adopt a sound format that has such a difference in sound level between stereo and mono.

This is, indeed, fabulous. As a musician and dabbler in home recording I would LOVE to be able to acquire this algorithm or I Tunes app. Is it available?
(Again, thank you for a mind blowing experience. I had to re-listen to it on my computer to get the full effect.)

This is amazing work. I've felt for some time that Ipods and digital music generally strip out sound separation. I eagerly await for this sound system to be "available at a store near you".

This is fantastic. I would fully support this to catch on.

Ultra cool. Can't wait to hear things I've listened to for years in this way like Sargent Peppers Lonely Hearts Club Band or Holst's The Planets. Or most anything! Whippoorwills(?) on the Wyoming plain.

When, oh when, can we get our hands on this technology? I'm always amazed that the latest innovations that could be utilized to enhance sound quality are quickly gobbled up by film, games, etc. and often don't even make it to music playback itself! Not only did CDs not get replaced by DVDs for music, but music went in the opposite direction, with CD quality being downgraded into compressed tracks that flattened soundstage, etc. (ITunes sells only compressed files). I'm wondering if the inventor is considering offering this software for sale as a digital download, so we can add it to our ITunes or other playback servers and finally have a step forward in the playback of our music. Great work!

It would be nice to hear a symphony with some dimension.

Song request:

Muse - "Exogenesis: Symphony Part 1 (Overture)"

Star Wars. Nuff said.

"What music or sound do you want to hear in 3D? Leave a comment and let us know."

Stravinsky's Le sacre du printemps!!!

Paul Klipsh long ago worked toward this. I believe all the examples prior were miraculous in themselves. Mr Choueiri appears to have tapped recent technologies to simplify it all. It was truly remarkable. It was completely gimmick and effect neutral. It seemed like I was in my beloved river searching for dragonflies as the bird erupted

The headset sound demonstration here is equally impressive. It succeeds in making the sound appear to be “out there” rather than inside one’s head. Obviously, there is no cross-channel crosstalk in a headset. I am guessing that in this modality crosstalk is actually added, as it is in the Dolby Headset system. I often use a headset when watching noisy movies out of consideration for other people in my light frame house. This would be a welcome enhancement. When is some version of this going to be on the market?

You can use 3D sound placement with musical cues to enable a blind person to fly an airplane. Pitches and rhythmic values, arranged in space and time could enable a blind person to take off, climb to altitude, level-off and return home and land safely.

From a fellow audiophile and amateur loudspeaker designer - very impressed, indeed. Another attribute of sound that I have felt was important was flat power response along with flat frequency response. If Dr. Choueiri’s method allows for against-the-wall speaker placement, then requirement for baffle diffraction step compensation disappears and power response = frequency response. Would love to hear B minor mass.

Listening to the outdoor water and birds recording was very calming and relaxing. With my eyes closed I had the perception of being in situ. I can imagine that this type of audio experience would have many applications for music therapy, say in hospitals.

Am I right in thinking that this concept would not work in a living room environment with a family sitting on a couch around a TV? If this technology does make it into living rooms, it seems that there would have to be a way to disable the feature during times when a large audience is gathered around a single focal point with vastly different points of perspective.

I believe Mathew Polk incorporated this idea of subtractive crosstalk into his SDA (Stereo Dimensional Array) line of speakers beginning in 1985. They utilized a second driver in each speaker to cancel the crosstalk from the opposite speaker. I paid $2600/pair for these speakers and still use them today.

I like the sound, but I can´t listening a true 3d... :(

There is no sound on my feets or above my head.

In this other video I feel the sound in 3d.

What creativity!
I also vote for the Nobel Prize
Edgar, you honor all those of Lebanese descent.

I know Edgar as a friend and I have experienced his 3D sound on several occasions. It is for real, and I believe it will revolutionize sound technology. Edgar is one of the smartest persons I know, and he's not the egghead you would expect him to be as a physics professor from Princeton. He's a down to earth, regular, nice guy who is very passionate about whatever he does. Edgar should be nominated for a Nobel prize for this invention.

Absolutely mindboggling! I cannot wait to hear my favorite concerts now comfortably from home, as up to now, it was always a disappointment when listening to the record or CD of a concert I had enjoyed on site.
John Nelson, our friend and Orchestra Director, currently performing St Matthews passion, in Paris and Chicago among others this year, will be enchanted.
Thank you, Edgar, for this magnificent contribution to the arts too.
