Princeton Professor Pioneers 3D Audio (via WNYC’s Studio 360)

Edgar Choueiri, the Director of Princeton University’s Electric Propulsion and Plasma Dynamics Laboratory, has developed an algorithm to produce sound in three dimensions from any two speakers. Studio 360 brings us the story here: http://www.studio360.org/2011/apr/29/adventures-3d-sound/.

It differs from surround sound in that rather than simply bombarding you with sounds from different directions, this technology simulates the minute time difference it takes for a sound to reach each ear. The result is that the listener can effectively pinpoint exactly where in space around him the sound is coming from. It’s really incredible and really worth hearing, even on your laptop speakers. Experience it for yourself:
