Princeton invention delivers 3D sound from ordinary laptop speakers

[VektaWarLord]

Did anyone els just realize at 4:31 that they had there earbuds in the wrong ears? : )

[caro2486]

edgar choueiri is called new einstein of modern time

he invented the plasma also

he is from lebanon

i have to say it , because lebanese people are very successful and integrate easily in their new countries and participate to make these countries advance in every field of life

ministers , congressmen , university chancelors , singers ( shakira , paul anka , massari , mika etc..) director of nasa , google ex-director and inventor of more than 80% of google's features etc....

[jfoley715]

It works better with headphones/ earbuds.

[desposyy]

damn...

[mishkacinco]

he looks like daron malakyan :D:D

[ryanadanderson]

So when doing this in a theater, like a cinema setting, would everyone need to be wearing headphones to feel like they are where the audio engineers want them to feel?

[ulisesrobles]

this is kind of an old thing, Pink floyd used this things in a few records and the algorithm for doing this is called CETERA (it's private). why is the "guy in the other room wearing headphones? wasnt it supposed to work even without them?

Search for "virtual barbershop"

[kludgedup]

@ulisesrobles Nope. That's different. That uses headphones. What's talked about in this video doesn't need headphones. The guy explains why about halfway through the video.

[edinayc]

Will this technique work for more than one person? seem like you have to be positioned precisely.

[burto]

I would not trust this man if weren't for his pipe.

[MetalUpYourEar]

Imagine using this for dubstep....

[AndrosForever]

@MetalUpYourEar I think I would be the first guy to experience multiple orgasms

[austenwack]

Interesting how headphones already...

[greenops]

@austenwack Yes headphones can do this, but no one records audio the correct way for sound to be truly 3d.

He is continuing work of others essentially (stuff like this watch?v=8IXm6SuUigI ) He's taking it further by trying to get this to work without headphones.

[austenwack]

@greenops Wow, okay. Well that's pretty cool and makes a lot more sense. Heh, thank you for clarifying, I appreciate it.

[QraQrJaq]

so awesome, i wanna start recording music like this! is the a neumann manaquin head?? thats gotta be expensive..

[gatepc]

High end 2 channels systems have already had the clarity and soundstaging capabilities to let you do this with standard recordings for the last 40 years or so. Granted you needed to spend a good amount of money on it. I'm speaking of systems roughly starting at the 5K mark and up.

[technoir08]

You know that pipe he's smoking is full of weed!



[VHS2DVDSYD]

watch?v=L9__kIwhBaE this will be real 3d sound!

[rhymeschemes]

I really, really hate videos like this.

I'm deaf in one ear. There is no such thing as "3D sound" for me.

Makes me jealous.

[tigernac]

wow, i pointed in the exact same places !!!!!!

[sidhudalwinder]

hai this is Dalwinder Singh Sidhu I was very happy to see your video. I did same thing by putting analog processor in front which senses the phse and amplitude and

deliver 3d sound .That one is under patent . Thanks

[Gart7]

Is this just a commercial for the neumann head?

[ilam3d]

I like it.

[AtTheSpeedOfCheese]

Dat man be smokin' dat pipe!

[icef1sh]

this is nothing new. I hate when people talk about a technological advancement and simultaneously talk about their own work, almost insinuating that they developed the technology.

[skyminex]

so if someone does a fart during a conference we can tell who did it?

[justromeo]

@skyminex only if you hear it. I can get all of you out of the conference room without a sound.

[DarienCaldwell]

Creative had this with their SoundBlaster sound cards 10 years ago. Not very new or extrordinary.

[cethommecharmant]

No mention of how the technology captures the depth of sound (eg, to identify whether a noise occurs directly above or below the listener). Shouldn't this be called 2D?

[PuraVid4]

I dont really hear it. I can tell where the sound is "supposed" to come from but it doesnt sound 3d. I hear it as if something is coming either from left speaker or right speaker. but Ive heard this often in music.

Is he able to get sound behind the viewer?

[AmyLoveFun]

@PuraVid4 I actually heard the fly behind my head.

[neomp5]

i'm a very amateur sound designer, and i'm just picturing how much fun it would be to have software that would allow for mixing sound effects in 3d. how well does it work on the up and down axis? can you hear a sound rise?

[maluca1234]

All I know is that I could have edited the dialog of this video way better  :P

[TheFritoPundito]

As far as I can tell (I'm an auditory scientist) there isn't anything really new in this. Using HRTFs has been around for a while, as have crosstalk cancelling mechanisms. The localization demo he shows is not unusual - you can get angular acuity like that with almost any spatial algorithm. So I'll hold off on buying whatever it is that he is selllng.

[areyoucursed]

@TheFritoPundito I was thinking the same thing (not a scientist by any means, just an audio enthusiast). Isn't this just an implementation of binaural recordings? I was curious if his crosstalk algorithm was any different than ones already released. If you don't mind, can you link to a few articles/research papers regarding this phenomenon? I'd love to read up on it.

[Godknown]

I love when he said that in movies, the visuals are great, but the audio is lousy.

[MrDucktaper]

Is that the "Kingston" guy? o.O!

[davewatcher]

Can more that one person experience this at the same time?

[artifactingreality]

Just sounds like regular stereo to me.

[PajakTheBlind]

Professor Choueiri you're my hero!

So would it work with HRTF function plus applying the filter?

[PajakTheBlind]

Professor Choueiri you're my hero!

[recneps96]

Search virtual barbershop here on youtube... Also, why not just wear headphones?

[Godknown]

@recneps96 You will never get the same experience because [research on google]

[recneps96]

@Godknown I'm sure it's better, but it's not like we haven't had similar technology for a long time.

[neomp5]

@recneps96

it's not the technology so much as how it's used, and it creates a sound that no other method can even come close to. surround sound only creates a pale imitation of directionality.

[YoanSegot]

Realy cool, this technology has existed for years, called transaural sound (binaural, if used with headphones). You can go even further with ambisonic sounds and WFS. Check them out for some cool stuff!

[Agemrepus]

this works well with my headphones too

[sw204me]

My turtle beach headset does all this for me.

[GuinnessKMF]

Whoa, what's that visualization of audio at 5:44? Talk about that more...

[christopheraho]

@GuinnessKMF That looks like lens flare and not anything audio related. It's from the light pointing into the camera's lens.

[GuinnessKMF]

@christopheraho Hah! I never even noticed the camera was panning by a laser, you're absolutely right, it's just a really cool looking lens flare. The flare was just too cool looking to actually notice the subject of that shot.

[XxxStarShip]

@GuinnessKMF That's a laser measurement device...

[GuinnessKMF]

@XxxStarShip Correction, it's a "kickass lens flare generator"!

[marccisa]

It's incredible! I'm half deaf on my left ear so i usually have problems to localize sounds; i don't know how but i could localize all sounds from this video correctly without any problem at all. It's a great invention which can be used in many, many things.

[gevse]

A great teacher, gave me a B+, I thought I deserved an A-, he didn't bend. Good guy.

[CalvinKhurniawan]

This gives me goosebumps.

[1Pantikian]

holy fucking shit! that was amazing, im crying

[DominicRiv]

America has the best universities.

[misternils]

yo where is the love for headphones

[homestar86]

@misternils Did you even watch the video?

[SimonJHarpham]

This is most awesome. When can I get this as a plug-in for music editing software?

[BarrellyRoll]

Epic dude. You can just tell he's a damn genius.

[nailstorm]

wow it actually bothered my head when the 3d sound pieces were on

[chairguru22]

Nintendo DS, DSi, 3DS all utilize a 3D sound effect. Ever use it and test it in the settings? Try it.

[YPchicken]

I didn't see(or hear) much of a problem with ear fatigue, however, the effect wasn't extremely strong, although it was there. Probably because of my laptop speakers being located at the lower end of my laptop....

[ste1438]

@DanePaulStewart We should trust you instead the Professor of Mechanical and Aerospace engineering then - "severe ear fatigue" and a headache after a couple minutes of listening. LOL

[Callanizy]

How does this work for things behind and in front of you?

[pimroes]

"This dummy head is recording this conference. Lucas is listening in another room in 3d." If they where so confident about there setup, why is the setup like this? x--------x x--------x x---X---x Instead of like a 3d-setup like this? ----x--x x----------x -----X----- x----------x ----x--x From the left-right speaker you hear on which side of the table they sit, and from the volume how far a way. This setup is a joke, and so is this "proof-of-concept" video..

[nskpsycho]

@pimroes but you know that it worked so maybe in their next video they will do as you please =D

[TheBerkeleyBear]

@pimroes your warrant is too incoherent to be taken seriously.

[sadeviant]

why is it that every time somebody "discovers" 3d sound it's always phase cancellation and they act like they're the first ones to know about it

[bgardineer4]

@sadeviant: This technique is unique because it uses frequency-dependent regularization, and therefore exhibits very little sound coloration for listeners both inside and outside of the sweet spot. True, the so-called "perfect" crosstalk cancellation filter was discovered long ago, but it's hardly perfect in practice. In fact, it actually sounds atrocious when you hear it. Furthermore, most phase cancellation 3-D audio systems require 6 or more speakers; this one requires only two.

[Phryxus13]

I don't hear a single difference..

[Cravall]

How is this 3D? You can't hear up or down, everything happens on your exact head level.

[nskpsycho]

@Cravall it's a start i guess =P

[wimbletone]

oh gooossshhhh i love this

[froilen13]

let the sound horing begins...

[Pez0023]

this whole experiment is really neat and all but it is all based on the fact that you are going to sit in one place and not get up to go anywhere. i see a possible connection to Kinect with its head locating technology

[sagewah]

I've still got an aureal soundcard that did this better a long time ago - and still would be if creative hadn't litigated them to death.

[bummers]

watch?v=LJwUVCXH-gM <-- this is even better!

[SquishyTHDM]

@bummers That requires headphones, and is a totally different concept.

[bummers]

@SquishyTHDM You right, it is a totally different concept, but it sounds better.

[SJGster]

In theory, would it be possible to run this filter on my music, so I don't need headphones to get the full stereo effect? Can I do that now, with some free software?

[ArcticFox1000000]

Q Sound did all this stuff 20 years ago

[therealmishkin]

this is what I would pay money for: have a tool that eliminates sounds from a side, so when you go to the movies you hear nothing from your back or if you work next to a loud person you can tune that sound out.

[CANxWExBExFRIENDS]

this really isnt that innovate, this technology was already invented by bose

[Gramsdaman]

@CANxWExBExFRIENDS bose headphones are hugely flawed, all they have going for them is "oh god, i can't hear anything" they have a huge missing frequency range, that they cover up with TONS of bass (because life is full of bass, right?).

Portapros for life.

[RJCleveland]

Same with the idea of putting two microphones on a fake head, to get a better soundstage. It's called binaural recording.

[RJCleveland]

"3D sound" filters have been around for years and years. Someone should let this guy know.

[lodoss900]

ever since I drop LSD and watched Gladiator and experience 3D Sound

I have been waiting for the technology to catch up.

finally!!

[octopuzziy]

shit my speakers are backwards

[nosneb1]

@octopuzziy Try turning off any audio enhancements. I had the same problem, until I turned it off.

[EthanJDeLano]

love the pipe.. haha

[IDreamInCode]

That doesn't work at all on my crappy Lenovo laptop speakers.

[DownOnMyLuck]

@IDreamInCode I have a pair of M-Audio AV40's and the regular stereo fly sounded better.  The conference room was a little more impressive maybe, but I don't see how that couldn't be done in stereo.

[IDreamInCode]

@DownOnMyLuck I'm thinking each set of laptop speakers are going to be so different there will be no way to program correctly for the differences without running an extremely intense calibration for each setup.

Even from one Lenovo to the next on the same line would have different audio properties. Hell, the amount of dust settling in my right speaker would also change the algorithm.

I've seen this promise/demonstration 10 years ago of 3D sound, and it gave about the same results.

[leightonhs]

very interesting

[swidd2]

So listening with headphones creates a sound filter/barrier for perfect 3D sound experience?

[CaptainSpork1337]

@swidd2 They can do. He talks about being able to locate each instrument as if it were coming from a specific location around your head. You can do this with a high quality set of headphones that have what is referred to as a good "soundstage."

[BBBSparky1]

Anyone else not notice a difference with the fly?

[d46512]

That looping music is so cliche in documentaries these days

[CheeseLoverBob]

Ugly Windows ClearType Helvetica rendering at the beginning. :/

[gonxok]

4 people are deaf.

[XNRiX]

@gonxok i was about reply the same ....

[akhiltuffy]

oh man, FPS are going to be so much more fun now. SO MUCH MOAR FUN!

[chriswickens]

He smokes around tape reels...Not really a good idea, especially from someone who's working on this technology and is that intelligent.

[JaykeisBrutal]

@chriswickens When you have a beard that is that amazing, you can do whatever you want!

[chriswickens]

@JaykeisBrutal You sir, are correct. I neglected the power of said beard!

[CheeseLoverBob]

@chriswickens Probably something the video’s producers told him to do. He’s still a genius.

[tommymandel]

This is reminiscent of Q-Sound, a technology developed in the 80's, that could make sounds appear to come from way outside the physical location of the speakers. Google it It was used on some records i played on. Our guru-engineer/producer thought it did its magic through bizarre phase manipulation algorhythms.This Princeton guy's innovation may be in his type of cancellation/filtering, but I was underwhelmed by the sound on this video. Sorry, but keep up the good work!

[tommymandel]

re: my previous post: GooTube won't let me post a url but the usual h and t and m and L, the colonic and Slash times two and the w's, followed by a dot and qsound with another dot, a com and slash and index, another dot, and HeyThat'sMe (just the capitalized initials) (but lower case) should getcha there...

[mrzack888]

this wuld be perfect for gaming, cuz im 2 cheap to buy surround sound for my gaming pc. and for pple that use earsets when playing CS.

[MrBananaMann]

@mrzack888 You might have not understood the video. If this comes out, surround sound will become obsolete, as surround sound is not 3D at all.

[jessejungle]

Wow... the last 40 seconds of audio was sweet.... I <3 my Mackies!!

[hjdutch]

im deaf in one ear, what is this?

[sabad666]

teach me how to dabke?

[cyphern]

What is the third kind of cue? He mentioned the differences in time and volume, but the third one was never discussed.

[Govannan]

@cyphern Could've been cut by the video producer for time constraints or because it was hard to understand or something.

[cyphern]

@Govannan I suspect that is why it was cut.

My curiosity about #3 is heightened because I am deaf in one ear, yet i retain an admittedly-diminished ability to locate the source of sounds . Since both of the methods mentioned require two functional ears, either the third method requires only one ear, or i'm just not fully deaf in that ear and still get a weak signal below what i consciously notice.

[gregarious24]

I had cinnamon toast for breakfast.

[detectiveinspekta]

I did work on beamforming so it could detect listeners. From this it could do the usual post-processing and wala! 3d sounds.

[plasmoske]

So basically it's stereo.

[JonnyMartinMoreschi]

@plasmoske Of course, but anyone can simplify...he explained it.

[plasmoske]

@JonnyMartinMoreschi shutup or bashed

[ToyanDicch]

I'm now worried that either my ears don't work or my brain is damaged, as I heard nor 'felt' any difference in the 3D sound to the standard sound. I think I'm broken.

[colloredbrothers]

@ToyanDicch

neither did I

[detectiveinspekta]

@ToyanDicch You need headphones. You did not understand what the guy was saying, you only cared about hearing some sounds.

[ToyanDicch]

@detectiveinspekta According to the bloke you need a left and a right speaker. According to the diagrams, you need a left and a right speaker in front of you. That's what I have.

[WxMLovatt]

Brilliant!

[ChineseKiwi]

that said, the samples could of been better with for example, having the listener at the centre of a conversation ala a binaural-like recording.

[trzaskubejbe]

It is just too sad that this guy is gonna get assasinated by some surround speakers manufacturer.

[pixLable]

This was amazing! And it did work on my lap top :D.

For people not experiencing it maybe your stereo separation is too low or maybe you're too far away from the lap top.

[ChineseKiwi]

@pixLable also works better if you have a laptop where the soundbar is going horizontally as opposed to vertically.

[ChineseKiwi]

*sigh* What 3d sound in this sense is alluding to is SOUNDSTAGE DEPTH and IMAGING. In a lot of surround sound DSPs, there is often a 'flat' image in which all the instruments and vocals are an equal distance away, which isn't real llife and is really '2D' sound. Remember IT IS 3D sound if you think about it. 2D is width x length right? Well, 3D is length x width x DEPTH. In this case, the depth perception of the sound.

Damn this 'WOW' generation and expects to be instantly pleasurised.

[Mecella21]

This sucjked

[mattCwu]

I was expecting to hear 3d sounds on my laptop speakers...

[zoo1619]

@mattCwu Me too. I was excited, but now dissapointed.

[tcdoe]

kind of disappointed that all the sounds were not '3D'.

in my system (2 high quality alesis speakers and sub.)

i didn't hear anything novel.

[dominiccss]

@tcdoe same

[Aepotheosis]

@tcdoe Maybe you weren't listening well enough. I noticed it fine. Or hey, that could just be the placebo effect.

[ChineseKiwi]

@tcdoe mainly because you already have a sense of soundstage depth with correctly positioned speakers. With '3D sound', it's the IMAGING and audio positional cues that counts, not so much completely surround. EVERYONE is missing the point of this and understanding of this. Everyone's thinking of what 3D sound is is flawed and as I've explained, it IS 3D if you think about it. What this does is better correct the imaging via soundstage depth and imaging.

[ut2k4wikichici]

FPS games have the best Audio and have been doing this for years, the best 3d sound i have heard is from a Stereo Headset.

[WizHard]

@ut2k4wikichici What the beard man tries to do, it having 3D sound with speakers and not headphones.

In the video he explains that this is two different cases : with headphones stereo channels are separated, but with speakers a sound destinated to your left ear will also arrive to your right ear. And vice versa breaking the 3D effect. They used a simple physics phenomena to cancel this effect.

The idea is great, but I suspect it only work with very precise speakers configuration and listener.

[Spo8]

Can we please talk about what happens at 5:43? I do not understand it and I would like to.

[SpeakMouthWords]

@Spo8 I think it's just an effect of the lens of the camera. But it sure looks like some crazy hologram thing.

[btothe18]

Awesome guy. I wanna research with this dude.

[watsxn]

this only works if they have stereo speakers, or properly setup surround sound

[seraph2099]

one thing he didnt mention.. 3D sound has existed for years.. its called HEADPHONES...

[Rav3nXTC]

@seraph2099 You're stupid, right? He's trying to create 3D sound for speakers. Of course you can imitate 3D sound through headphones but that's not the idea of his project. He wants 3D sound from speakers. Get your head checked, fuck face.

[seraph2099]

@Rav3nXTC HAHAHHA you made me laugh man.

I'm clearly trolling but yes the last time I checked my head.. I was wearing headphones.

[V2Blast]

@Rav3nXTC You could have said the same thing without insulting him, you know.

[Mentisia]

@seraph2099 it's called socializing, do you know it?

[maxxap]

you see that beard, you know you're in safe hands.

[Chubigans]

@maxxap that is a beard of academic excellence

[slicedoranges]

@maxxap Typical YouTube retard.

[bobogaulout]

@maxxap don't forget about the pipe, you can't ignore a guy who smokes a pipe

[fridgelamp]

It's amazing this guy has so much passion for what he does. I hope this catches on.

Also, sick pipe brah.

I would love to see this technology released. I currently get a similar effect with my Polk SDA (Stereo Dimentional Array) speakers from the mid 1980's. The sounds
