A room-compensated virtual surround system exploiting early reflections in a reverberant room

In this paper we propose a novel methodology for rendering a surround sound in a prescribed area using a loudspeaker array, which exploits the early reflections on the walls of the room. With respect to the state of the art, the proposed technique is able to take advantage of the knowledge of the acoustic scene (i.e. room geometry and reflective properties of the walls) in order to reduce undesired wall reflections. Simulative results show that the use of room compensation enables an improved accuracy of the virtual surround.
