    Abstract: In general, techniques are described for indicating reuse of a syntax element indicating a vector quantization codebook used in compressing a vector. A device comprising a processor and a memory may perform the techniques. The processor may be configured to obtain a bitstream comprising a vector in a spherical harmonics domain. The bitstream may further comprise an indicator for whether to reuse, from a previous frame, a syntax element indicative of a vector quantization codebook used when compressing the vector. The memory may be configured to store the bitstream.

    Abstract: In general, techniques are described for obtaining decomposed versions of spherical harmonic coefficients. A device comprising a processor and a memory may be configured to perform the techniques. The processor may obtain a non-zero set of coefficients of a vector representative a distinct component of a sound field. The vector may have been decomposed from a plurality of spherical harmonic coefficients that describe the sound field. The processor may also obtain one of a plurality of configuration modes by which to extract the non-zero set of coefficients of the vector, where the one of the configuration modes indicates that the coefficients include all of the coefficients except for at least one of the coefficients. The processor may further extract the coefficients of the vector based on the obtained one of the configuration modes. The memory may be configured to store the non-zero set of the coefficients of the vector.

    Abstract: In general, techniques are described by which to perform spatial masking with respect to spherical harmonic coefficients. As one example, an audio encoding device comprising a processor may perform various aspects of the techniques. The processor may be configured to perform spatial analysis based on the spherical harmonic coefficients describing a three-dimensional sound field to identify a spatial masking threshold. The processor may further be configured to render the multi-channel audio data from the plurality of spherical harmonic coefficients, and compress the multi-channel audio data based on the identified spatial masking threshold to generate a bitstream.
