摘要
In general, techniques are described by which to perform spatial relation coding of higher order ambisonic coefficients using expanded parameters. A device comprising a memory and a processor may perform the techniques. The memory may be configured to store at least a portion of a bitstream, the bitstream including a first indication representative of an HOA coefficient associated with the spherical basis function having an order of zero, and a second indication representative of one or more parameters. The processor may be configured to perform parameter expansion with respect to the one or more parameters to obtain one or more expanded parameters, and synthesize, based on the one or more expanded parameters and the HOA coefficient associated with the spherical basis function having the order of zero, one or more HOA coefficients associated with one or more spherical basis functions having an order greater than zero.
