Abstract
<p indent="0mm">Spatial sound aims to record, transmit, and reproduce the spatial information of the sound field and recreate the desired spatial auditory events or perceptions. It is a frontier field in acoustics and has undergone rapid advancement recently. It has also been widely used in scientific research, engineering technology, and cultural entertainment. The physical analysis of the sound field and the spatial auditory perception mechanism are two foundations of spatial sound. Signal processing is a technical approach for implementing spatial sound. Therefore, spatial sound handles fundamental and technical problems of sound field, hearing, and practical implementation in the crossfield of acoustics (physics), auditory perceptions, and signal processing. The principle, development, key scientific and technical problems, progress, and representative applications of spatial sound are reviewed in this article. Moreover, the technical and application prospects of spatial sound are addressed.
