Research Project

Towards Objective Assessment of Spatial Audio Quality of Loudspeaker-Based Systems in Cars

Car audio system design and optimisation can be time consuming. The process could be shortened if tools for automatic assessment of perceived sound quality were available. This project concerns one of these tools, involving a model for objective assessment of spatial audio attributes, and subsequent manual optimisation of spatial audio quality playback in automotive sound systems.
