Low-complexity, listener’s position-adaptive binaural reproduction over a loudspeaker array

Low-complexity, listener’s position-adaptive binaural reproduction over a loudspeaker array
Low-complexity, listener’s position-adaptive binaural reproduction over a loudspeaker array
This work presents a method for binaural reproduction over a loudspeaker array that adapts to the listener’s position by using a cross-talk cancellation approach that is updated in real-time. This is obtained by combining the audio signal processing system together with a computer vision mechanism that estimates listener’s position. A novel approach to adapt the cross-talk cancellation filters is introduced here, which employs filters created for a central listening position using a free-field propagation model and far field beamforming techniques, hence
requiring little memory and processing. The paper introduces simulations to show the effectiveness and robustness of the formulation together with free-field measurements of performance using a 16 loudspeaker compact array.

Abstract

This work presents a method for binaural reproduction over a loudspeaker array that adapts to the listener’s position by using a cross-talk cancellation approach that is updated in real-time. This is obtained by combining the audio signal processing system together with a computer vision mechanism that estimates listener’s position. A novel approach to adapt the cross-talk cancellation filters is introduced here, which employs filters created for a central listening position using a free-field propagation model and far field beamforming techniques, hence
requiring little memory and processing. The paper introduces simulations to show the effectiveness and robustness of the formulation together with free-field measurements of performance using a 16 loudspeaker compact array.
