Abstract
An apparatus comprising means for: obtaining a bitstream comprising encoded spatial metadata and encoded transport audio signals; decoding transport audio signals from the bitstream encoded transport audio signals; decoding spatial metadata from the bitstream encoded spatial metadata; generating an encoding metric; and generating spatial audio signals from the transport audio signals based on the encoding metric and the spatial metadata.
Claims22
An apparatus comprising at least one processor;
- and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus to at least:
- obtain a bitstream comprising encoded spatial metadata and encoded transport audio signals;
- decode transport audio signals from the bitstream encoded transport audio signals;
- decode spatial metadata from the bitstream encoded spatial metadata;
- generate an encoding metric;
- and
- generate spatial audio signals from the transport audio signals based on the encoding metric and the spatial metadata.
(canceled)
A method comprising:
- obtaining a bitstream comprising encoded spatial metadata and encoded transport audio signals;
- decoding transport audio signals from the bitstream encoded transport audio signals;
- decoding spatial metadata from the bitstream encoded spatial metadata;
- generating an encoding metric;
- and
- generating spatial audio signals from the transport audio signals based on the encoding metric and the spatial metadata.
