Abstract

Scene-based audio (SBA) also known as Higher Order Ambisonics (HOA) combines the advantages of object-based and traditional channel-based audio schemes. It is particularly suitable for enabling a truly immersive (360, 180) VR audio experience. SBA signals can be efficiently rotated and binauralized. This makes realistic VR audio practical on consumer devices. SBA also provides conductive mechanisms for acquiring live soundfields for VR. MPEG-H is a newly adopted compression standard that can efficiently compress HOA for transmission and storage purposes. It is the only known standard that provides compressed HOA end-to-end. Our paper describes a practical end-to-end chain for SBA/HOA based VR audio. Given its advantages over other formats, SBA should be “the format of choice” for a compelling VR audio experience.
