Pioneered in the sixties, Crosstalk Cancellation (CTC) allows for immersive sound reproduction from a limited number of loudspeakers. Upcoming virtual reality and augmented reality applications, as well as widespread availability of 3D audio content, have boosted interest in CTC technologies over the recent years. In this paper, we present a novel multiband approach to CTC, evolving and superseding our original work based on modeling of the system’s geometrical acoustics. This new solution, whilst keeping a simple processing model, offers improved CTC effectiveness, reduced residual coloration and wider bandwidth. The enhanced performance of our new approach has been confirmed by laboratory experiments.
