Princeton invention delivers 3D sound from ordinary laptop speakers

Edgar Choueiri, a professor of mechanical and aerospace engineering at Princeton University, has developed a way to play true three-dimensional sound recordings over regular loudspeakers, such as those found in televisions and computer laptops.

The technique may one day be used to allow 3D televisions to produce lifelike sound and to help people with certain types of hearing impairments locate noises. Segments of the video above incorporate Choueri's 3D filter to demonstrate the phenomenon.

The filter is designed to work with loudspeakers - not headphones - and can be experienced through standard computer speakers. (Make sure the right and left speakers are on the correct sides.)

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

[GuinnessKMF]

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

[VektaWarLord]

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

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....

It works better with headphones/ earbuds.

[justromeo]

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

[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.

[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?
