Frequency-based customization of multizone sound system design

Abstract

Methods for generating multizone soundfield have a wide range of applications. The desired dominant frequency bands to be generated and perceived, however, are not the same for different applications. Previous work proposed a low complexity algorithm for multizone wideband sound field generation using a frequency variable dictionary in a Lasso-LS optimization. This work demonstrates the flexibility of the novel algorithm in imposing variable number of active speakers to provide the desired reproduction accuracy at variable frequency bands. The deployment of this technique can lead to the customization of multizone sound system design based on both signal frequency content and listeners' perception.
