Geometrical Acoustics Approach to Cross Talk Cancellation

Crosstalk Cancellation (CTC) is a signal processing technique allowing for immersive sound reproduction from a limited number of loudspeakers. Pioneered in the sixties, CTC has lately gained much attraction due to upcoming Augmented Reality and Virtual Reality applications and generalization of 3D audio content. In this paper, we present a novel time-domain approach to CTC based on modeling of the system’s geometrical acoustics. Our solution provides a simple processing model, as well as means to address robustness issues and adaptation to arbitrary listener positions.
