1. A method of generating a bitstream representative of a compressed version of audio content, the method comprising: obtaining, by a processor of a device, a plurality of spherical harmonic coefficients representative of the audio content; determining, by the processor and based on an analysis of the plurality of spherical harmonic coefficients, whether one or more of the plurality of spherical harmonic coefficients have information relevant in describing a sound field in three dimensions, wherein the plurality of spherical harmonic coefficients are representative of the sound field; specifying an indication, in the bitstream stored to a memory of the device and by the processor, identifying that the determined one or more of the plurality of spherical harmonic coefficients having the information relevant in describing the sound field are included in the bitstream, and that remaining ones of the plurality of spherical harmonic coefficients having information not relevant in describing the sound field are not included in the bitstream; specifying, in the bitstream and by the processor, the identified one or more of the plurality of spherical harmonic coefficients without specifying, in the bitstream, the remaining ones of the plurality of spherical harmonic coefficients having information not relevant in describing the sound field; determining, by the processor, a target bitrate for the bitstream including the identified one or more of the plurality of spherical harmonic coefficients; and bandwidth compressing, by the processor and according to the determined target bitrate, the identified one or more of the plurality of spherical harmonic coefficients in the bitstream.
