Abstract

In order to improve flexibility of surrounding stereo system, a novel system for 3D audio rendering is proposed in this paper based on multi-beam steering, which is composed of five beam units using linear loudspeaker arrays. By controlling accurately time delay or phase of loudspeakers, beam can be formed in a desired direction. The simulation results show that the proposed method is reasonable and effective.
