Abstract

The chapter outlines the concepts of Sound Quality and Quality of Experience (QoE). Building on these, it describes a conceptual model of sound quality perception and experience during active listening in a spatial-audio context. The presented model of sound quality perception considers both bottom-up (signal-driven) as well as top-down (hypothesis-driven) perceptual functional processes. Different studies by the authors and from the literature are discussed in light of their suitability to help develop implementations of the conceptual model. As a key prerequisite, the underlying perceptual ground-truth data required for model training and validation are discussed, as well as means for deriving these from respective listening tests. Both feature-based and more holistic modeling approaches are analyzed. Overall, open research questions are summarized, deriving trajectories for future work on spatial-audio Sound Quality and Quality of Experience modeling.
