Abstract
Examples of the disclosure enable spatial audio rendering in a different format to the format that is used for the spatial audio coding. In examples of the disclosure spatial audio and first spatial metadata in a first format are obtained. The first spatial metadata enables rendering of spatial audio in a first audio format. In order to enable rendering of the spatial audio in a different format the spatial metadata is converted to second spatial metadata corresponding to a second audio format. The spatial audio can then be rendered for the second format using the second spatial metadata.
Claims20
An apparatus for communication audio, comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus at least to:
- obtain an encoded spatial audio signal comprising one or more audio signals and first spatial metadata, wherein the first spatial metadata is configured to enable rendering of spatial audio in a first audio format based on the one or more audio signals;
- determine second spatial metadata using at least the first spatial metadata, wherein the second spatial metadata enables rendering of spatial audio in a second audio format based on the one or more audio signals;
- and
- enable rendering of the spatial audio in the second audio format using at least the second spatial metadata and the one or more audio signals.
A method for communication audio comprising:
- obtaining an encoded spatial audio signal comprising one or more audio signals and first spatial metadata wherein the first spatial metadata is configured to enable rendering of spatial audio in a first audio format based on the one or more audio signals;
- determining second spatial metadata using at least the first spatial metadata, wherein the second spatial metadata enables rendering of spatial audio in a second audio format based on the one or more audio signals;
- and
- enabling rendering of the spatial audio in the second audio format using at least the second spatial metadata and the one or more audio signals.
A non-transitory computer readable medium for communication audio comprising instructions stored thereon for performing at least the following:
- obtaining an encoded spatial audio signal comprising one or more audio signals and first spatial metadata wherein the first spatial metadata is configured to enable rendering of spatial audio in a first audio format based on the one or more audio signals;
- using, at least the first spatial determine second spatial metadata wherein the second spatial metadata enables rendering of spatial audio in a second audio format based on the one or more audio signals;
- and
- enabling rendering of the spatial audio in the second audio format using at least the second spatial metadata and the one or more audio signals.
