Abstract
In general, techniques are described for signaling channels for scalable coding of higher order ambisonic audio data. A device comprising a memory and a processor may be configured to perform the techniques. The memory may be configured to store the bitstream. The processor may be configured to obtain, from the bitstream, an indication of a number of channels specified in one or more layers in the bitstream, and obtain the channels specified in the one or more layers in the bitstream based on the indication of the number of channels.

A device configured to decode a bitstream representative of a higher order ambisonic audio signal, the device comprising:
- a memory configured to store the bitstream;
- and
- one or more processors configured to:
- obtain, from the bitstream, an indication of a number of channels specified in one or more layers in the bitstream;
- and
- obtain the channels specified in the one or more layers in the bitstream based on the indication of the number of channels.
A method of decoding a bitstream representative of a higher order ambisonic audio signal, the method comprising:
- obtaining, from the bitstream, an indication of a number of channels specified in one or more layers in the bitstream;
- and
- obtaining the channels specified in the one or more layers in the bitstream based on the indication of the number of channels.
A device configured to decode a bitstream representative of a higher order ambisonic audio signal, the device comprising:
- means for obtaining, from the bitstream, an indication of a number of channels specified in one or more layers of the bitstream;
- and
- means for obtaining the channels specified in the one or more layers in the bitstream based on the indication of the number of channels.
A non-transitory computer-readable storage medium having stored thereon instructions that, when executed, cause one or more processors to:
- obtain, from a bitstream representative of a higher order ambisonic audio signal, an indication of a number of channels specified in one or more layers of the bitstream;
- and
- obtain the channels specified in the one or more layers of the bitstream based on the indication of the number of channels.
A device configured to encode a higher order ambisonic audio signal to generate a bitstream, the device comprising:
- one or more processors configured to specify, in the bitstream, an indication of a number of channels specified in one or more layers of the bitstream, and specify the indicated number of the channels in the one or more layers of the bitstream;
- and
- a memory configured to store the bitstream.
A method of encoding a higher order ambisonic audio signal to generate a bitstream, the method comprising:
- specifying, in the bitstream, an indication of a number of channels specified in one or more layers of the bitstream;
- and
- specifying the indicated number of the channels in the one or more layers of the bitstream.
