ORDER FORMAT SIGNALING FOR HIGHER-ORDER AMBISONIC AUDIO DATA

摘要

In general, techniques are described for signaling an order format for higher-order ambisonic audio data. An audio decoding device including a memory and a processor may perform the techniques. The memory may be configured to store a bitstream indicative of a coded higher-order ambisonic (HOA) audio signal. The processor may be configured to obtain, from the bitstream, a harmonic coefficient ordering format indicator indicative of a symmetric harmonic coefficient ordering format for a source set of HOA coefficients from which the coded HOA audio signal is generated. The processor may further be configured to decode the coded HOA audio signal based on the symmetric harmonic coefficient ordering format indicator.
