Object-Based Audio Reproduction using a Listener-Position Adaptive Stereo System

This work introduces a listener-position adaptive stereo reproduction system 10 that allows for the reproduction of 2D object-based audio and for a more accurate 11 localisation when the listener is located outside the sweet spot. The adaptation is 12 composed of two parts; a compensation system that updates the loudspeakers feeds 13 so that the loudspeaker input signals are delivered to the listener with the same 14 magnitude and phase independently of the listening position, as it would occur in 15 a symmetric listening configuration, and an object-based rendering system using 16 conventional panning algorithms. Robustness simulations show that an accurate 17 localisation is possible when the audio objects are panned in the angle seen between 18 the listener and the two loudspeakers. This has been further assessed by objective 19 and subjective localisation experiment
