An advanced spatial sound reproduction system with listener position tracking

The paper deals with the development of a real time system for the reproduction of an immersive audio field considering the listeners´ position. The system is composed of two parts: a sound rendering system based on a crosstalk canceller that is required in order to have a spatialized reproduction and a listener position tracking system in order to model the crosstalk canceller parameters. Therefore, starting from the free-field model, a new model is considered introducing a directivity function for the loudspeakers and considering a three-dimensional environment. A real time application is proposed introducing a Kinect control, capable of accurately tracking the listener position and changing the crosstalk parameters. Several results are presented comparing the proposed approach with the state of the art in order to confirm its validity.
