immersive audio,spherical harmonic expansion,spherical loudspeaker array

Approaches to achieving highly immersive audio reproduction are generally categorized into methods based on psychoacoustic models and those grounded in physical acoustic models. Physical acoustic models reconstruct the physical wavefronts surrounding the listener, thereby enabling the expression of depth perception in the sound image. This report provides an overview of a spherical loudspeaker array that facilitates real-time reproduction of virtual sound sources using spherical harmonic expansion of the sound field.
