of Berlin. The room contains the world’s largest speaker system with 2700 loudspeakers on 832 independent channels. Research trends in wave field synthesis include the consideration of psychoacoustics to reduce the necessary number of loudspeakers, and to implement complicated sound radiation properties so that a virtual grand piano sounds as grand as in real life.
