AB  - By controlling sound delivery at the listener’s ears, Crosstalk Cancellation (CTC) allows for 3D audio reproduction from a limited number of speakers by simulation of binaural cues. Originally pioneered in the sixties, CTC is currently an active field of research due to increased interest in Augmented Reality (AR) and Virtual Reality (VR) applications and widespread availability of immersive audio content. In this paper, we present an extension of our multiband, geometrical acoustics inspired, CTC solution able to support a freely moving user. Unlike the static case, support of a moving user requires the ability to update CTC filters in real-time. Being rooted in the time-domain, our solution offers natural support for continuous adaptation to changing conditions. The effectiveness of the proposed solution is verified by laboratory experiments.
