Audio interface for immersive 3D-audio desktop applications
نویسندگان
چکیده
An immersive audio environment for desktop applications is presented. It allows the spatialisation of 3D sound fields around an almost free mobile listener. The sound field is reproduced by a several loudspeakers positioned along the desktop edges without using head tracking. The loudspeaker signals are derived by using the principle of the 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 reproduction and the efficency of different panning algortihms will be investigated.

متن کاملFundamental and Technological Limitations of Immersive Audio Systems
Numerous applications are currently envisioned for immersive audio systems. The principal function of such systems is to synthesize, manipulate, and render sound fields in real time. In this paper, we examine several fundamental and technological limitations that impede the development of seamless immersive audio systems. Such limitations stem from signal-processing requirements, acoustical con...
