The 3D Future of Sound

Dr Edgar Choueiri at Princeton University is similarly developing 3d audio presentations over two audio channels. [1]

He has initially targeted audiophiles [2], and he has teamed with David Chesky (HDtracks.com) on a number of "binaural+" recordings. [3]

His video lecture and demo is nicely done (demo at 6 minute mark). [4]

The article makes it sound like that these techniques are ground breaking new, but in reality 3D software sound has existed for a long time already.

This would be nice for hearing aids too, just sayin.
