A listener adaptive optimal source distribution system for virtual sound imaging

A listener adaptive optimal source distribution system for virtual sound imaging
This paper describes the use of an optimal source distribution loudspeaker array for binaural reproduction. In this paper, the device is made adaptive to the listener’s position. This is obtained by using a fixed set of crosstalk cancellation filters created for a central listening position plus a listener-position dependent delay network, which varies the delay of each loudspeaker unit to maximise the cross-talk cancellation response at the listener’s position. The paper introduces the formulation required for the adaptive control and simulated results predicting the performance of the device for symmetrical and asymmetrical listening positions. It is also shown how the proposed formulation has been implemented on a Sherwood S7 OPSODIS soundbar.

Abstract

This paper describes the use of an optimal source distribution loudspeaker array for binaural reproduction. In this paper, the device is made adaptive to the listener’s position. This is obtained by using a fixed set of crosstalk cancellation filters created for a central listening position plus a listener-position dependent delay network, which varies the delay of each loudspeaker unit to maximise the cross-talk cancellation response at the listener’s position. The paper introduces the formulation required for the adaptive control and simulated results predicting the performance of the device for symmetrical and asymmetrical listening positions. It is also shown how the proposed formulation has been implemented on a Sherwood S7 OPSODIS soundbar.
