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.
Claims22
A computer-implemented method for creating a custom mix of different spatial audio objects, the method comprising:
- receiving a selection of a first input spatial audio object;
- receiving a selection of a first portion of a custom mix visualization where sound of the first input spatial audio object is to be rendered;
- receiving a selection of a second input spatial audio object;
- receiving a selection of a second portion of the custom mix visualization where sound of the second input spatial audio object is to be rendered;
- and
- generating a new spatial audio object that represents an array of virtual sound sources that define a sound field of the new spatial audio object, wherein sound of the first input object forms a part of the array of virtual sources, and sound of the second input object forms another part of the array of virtual sources.
A computer system for creating a custom mix of different of spatial audio objects, the computer system comprising
- a processor and memory having stored therein instructions that when executed by the processor:
- receive a selection of a first input spatial audio object;
- receive a selection of a first portion of a custom mix visualization where sound of the first input spatial audio object is to be rendered;
- receive a selection of a second input spatial audio object;
- receive a selection of a second portion of the custom mix visualization where sound of the second input spatial audio object is to be rendered;
- and
- generate a new spatial audio object that represents an array of virtual sound sources that define a sound field of the new spatial audio object, wherein sound of the first input object forms a part of the array of virtual sources, and sound of the second input object forms another part of the array of virtual sources.
