  A3D
       
           (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.
