3D Audio From Ordinary Speakers (Video Demo)

This video takes a look at Edgar Choueiri, a professor of mechanical and aerospace engineering at Princeton University, who has developed a way to play three-dimensional sound recordings more accurately 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.)

Here’s another interview with Choueiri:

I haven’t seen any longer musical demos using this technology, but this looks like it could be a great tool for electronic musicians.

  1. its easy to imagine how useful this is for electronic music. I think soundscapes could sound amazing with 3d .

    I hope this guy makes a lot of money off this.

  2. Very acoustically pleasing 3D piece at the end of the interview, during the credits of the first clip! it seems to employ this 3D technique as it sounds very nice in my listening triangle formed by the studio monitors here. This is a fantastic technological breakthrough on so many fronts that it is very difficult at once to pin-point all of those areas that will benefit from the implementation.

    I do sincerely hope this technology moves into the consumer market sometime in the next year or so. It's on its way. Check this out: http://www.princeton.edu/3D3A/News.html

  9. Bolt them to the underside of your chair to experience Sensurround (perfect earthquake effects for cheesy 1970s disaster movies).

  10. Its nothing 100% new. In the late 1960s, Aiwa and Sony offered headphones with a pair of microphones mounted on the headband. around two-inches above the ears. These allowed pseudo-binaural recordings to be made.

    Binaural recording is a method of recording sound that uses a special microphone arrangement and is intended for replay using headphones. Dummy head recording is a specific method of capturing the audio, generally using a bust that includes pinnae (outer ears). Because each person's pinnae are unique, and because the filtering they impose on sound directionality is learned by each person from early childhood, the use of pinnae during recording that are not the same as the ultimate listener may lead to perceptual confusion.

    What is new at this experiment is that is possible to play it at speakers. But for me the demo in the video doesn't work as the same binaural with headphone.

    Check this with you headphones…

  16. That's the whole point, if I understood correctly: the effect is much more difficult to achieve with loudspeakers than with headphones, because of the crosstalk.

  17. Interesting, but I'd really like to hear more examples and less talking about how fantastic it is.

    If this works over standard speakers, why can't they post more demos?

  19. it sounds like this doesn't change how you record things or mix them, but is just an effect used at the output stage.

    I'm not sure how this would work in real life scenarios. If you had more than two speakers, like on a car stereo, wouldn't things get weird really quick?

  26. OK, great, but what if you can't sit in the "sweet spot", for instance in a room full of people watching tv, and you're sitting in front of the left or right speaker?
