A quantitative evaluation of media device orchestration for immersive spatial audio reproduction

摘要

Media device orchestration (MDO) is the concept of using an ad hoc array of devices to deliver or augment a media experience. This paper describes a multiple stimulus rating experiment designed to evaluate the overall quality of listening experience (QoLE) of a range of common home audio systems (mono, two-channel, and five-channel) and two audio MDO systems. Twenty-six experienced listeners performed the experiment in two listening positions (on and off sweet spot) for three program items. Kruskal-Wallis tests revealed significant differences in QoLE between the evaluated systems. Post-hoc Wilcoxon signed-rank tests suggested that MDO can perform similarly to two- and five-channel systems in the on sweet spot listening position, and improve the QoLE off sweet spot.
