An efficient implementation of acoustic crosstalk cancellation for 3D audio rendering

Abstract

The paper deals with the development of an efficient real time system for the reproduction of a spatialized audio field taking into account 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 audio reproduction and a listener position tracking system in order to model the crosstalk canceller parameters. Then, an efficient implementation of a time domain crosstalk cancellation algorithm is presented considering an improved version of the recursive ambiophonics crosstalk elimination algorithm. A real time application is proposed introducing a Kinect control, capable to accurately track the listener position and changing the crosstalk parameters related to its position. Several results are presented comparing the proposed approach with the state of the art in order to confirm its validity.
