Audio interface for immersive 3D-audio desktop applications

An immersive audio environment for desktop applications is presented. It allows the spatialization of 3D sound fields around an almost free mobile listener. The sound field is reproduced by several loudspeakers positioned along the desktop edges without using head tracking. The loudspeaker signals are derived by using the principle of wave field synthesis approach combined with different panning techniques to overcome the insufficient loudspeaker layout. Virtual sources can be positioned in azimuth, elevation, and distance too. However, the reproduction area around the listener and the possible source space is restricted to a defined area. The quality of the reproduction and the efficiency of different panning algorithms will be investigated.
