A3D Definition

(Aureal 3-Dimensional?) A technology developed by {Aureal} that delivers sound with a three-dimensional effect through two speakers.  Many modern {sound cards} and PC games now support this feature. A3D differs from the various forms of {surround sound} in that it only requires two speakers, while surround sound typically requires four or five.  It is sometimes less convincing than surround sound but is supposedly better in {interactive} environments.  For example, PC games in which sounds often move from one speaker to another favour A3D, while pre-recorded video favours surround sound. {Home (http://www.a3d.com/)}.
