In general, techniques are described by which to perform bitrate allocation with respect to higher order ambisonic (HOA) audio data. A device comprising a memory and a processor may be configured to perform various aspects of the bitrate allocation techniques. The memory may be configured to store a spatially compressed version of the HOA audio data. The processor may be coupled to the memory, and configured to perform bitrate allocation, based on an analysis of transport channels representative of the spatially compressed version of the HOA audio data, and prior to performing gain control with respect to the transport channels or after performing inverse gain control with respect to the transport channels, to allocate a number of bits to each of the transport channels. The processor may also be configured to generate a bitstream that specifies each of the transport channels using the respective allocated number of bits.
