A LOUDSPEAKER ARRAY FOR 2 PEOPLE TRANSAURAL REPRODUCTION
M SIMÓN, Filippo Maria Fazi · 2024
Transaural reproduction allows rendering 3D binaural audio through loudspeakers. Although this is a field that has been extensively studied for single-listener reproduction, reproduction of Transaural audio for more than one listener is still an open research question. This paper introduces a signal processing approach for performing 2-people Transaural reproduction using a combination of 2 single-listener cross-talk cancellation (CTC) beamformers, so that the CTC is maximised at one listener position and the beamformer side-lobes radiate little energy not to affect the other listening position. Off-line response predictions using measured transfer functions show a performance similar to that which would be obtained using more complex approaches, where the sound-field is controlled at the ears of both listeners simultaneously.
