With the advent of binaural technology and cross-talk cancellation for loudspeakers, simulations of the traditional surround sound systems have been made possible through the placement of virtual sources in the same locations as their physical counterparts [1]. While oftentimes these simulations perform reasonably well, ambiguities and differences can arise due to practicalities such as generalised HRTF models, source-listener misalignments and naturally induced listener’s head movements. The resultant issues, such as front-back confusion, are generally obstructive towards a fully-immersive listening experience.This paper is concerned with improvements made to a listener-adaptive, cross-talk cancelling sound bar that is designed to simulate a 7.1 surround sound system. A novel approach for improved localisation of the rear sources is reviewed, involving the implementation of a head-rotation compensation system to its binaural encoding module.
