Listener adaptive filtering strategies for personal audio reproduction over loudspeaker arrays
Listener adaptive filtering strategies for personal audio reproduction over loudspeaker arrays
This paper describes the creation of dynamic filters for listener position adaptive personal audio reproduction with loudspeaker arrays. The proposed filters allow for the delivery of personalised audio programs to a pair of listeners. The filters are adapted in real-time to the listeners’ position, which can be estimated by a listener-tracking device. This is obtained by expressing the impulse response of each filter as a network of variable gain-delay elements that are updated so that the filters adjust the reproduced beam pattern to the listeners’ position, assuming that each loudspeaker behaves according to a point-source radiation model. This work introduces the formulation of the filters and presents numerical simulations of the system performance.

Abstract
This paper describes the creation of dynamic filters for listener position adaptive personal audio reproduction with loudspeaker arrays. The proposed filters allow for the delivery of personalised audio programs to a pair of listeners. The filters are adapted in real-time to the listeners’ position, which can be estimated by a listener-tracking device. This is obtained by expressing the impulse response of each filter as a network of variable gain-delay elements that are updated so that the filters adjust the reproduced beam pattern to the listeners’ position, assuming that each loudspeaker behaves according to a point-source radiation model. This work introduces the formulation of the filters and presents numerical simulations of the system performance.
