Abstract
Spatial audio upmixing enables mixing spatial sound on a more granular per-channel level than is possible using conventional upmixing. A spatial bed is a multi-channel audio content that represents a complete sound field description, e.g., a virtual sphere of sound, for example surrounding a simulated reality listener in a simulated reality environment. A new spatial bed is generated by combining sections of at least two of such spatial beds. Other embodiments are also described and claimed.
