The overarching aim of the project was to synthesise the sound field at a location in the recording volume using a limited number of RSMA recordings of the acoustic scene. Techniques were developed to that aim will include sound field extrapolation using spherical harmonic decompositions and object-based sparse approximations using a dictionary-based representation of the plane wave decomposition of the sound field. The planned research also includes work on transcoding the sound field for interactive binaural reproduction. Specifically, transcoding between interpolated higher-order Ambisonics and binaural audio will be investigated. The theoretical results of the project were be validated using real recordings.

“Spatial audio reproduction using analysis-based synthesis techniques”
This project aims to develop a spatial audio recording, coding, reproduction chain based on the analysis of sound scenes from recordings made with special microphone arrays. The project will investigate novel sound source localisation and separation algorithms and direct/diffuse separation from recordings; develop sound scene authoring tools and necessary methods for 3D and spatial sound source generation.

“Sound source localisation using open spherical acoustic intensity probes”
This project aims to design and develop open spherical microphone arrays to accurately measure acoustic intensity and use the acoustic intensity vectors for localising sound sources, even under highly reverberant environments.
