1. A device for decoding encoded higher order ambisonics (HOA) coefficients representative of a soundfield, the device comprising: a memory configured to store the encoded HOA coefficients representative of the soundfield; and one or more processors, when configured to decode the encoded HOA coefficients stored in the memory, being configured to: receive, as part of an encoded bitstream including the encoded HOA coefficients, an audio object representative of the encoded HOA coefficients; receive bit-allocation metadata indicative of an allocation of a number of bits of the encoded bitstream to the audio object of the soundfield; extract, based on the bit-allocation metadata, the number of bits from the encoded bitstream to parse the audio object from the encoded bitstream; render, based on the audio object, one or more speaker feeds; and output the one or more speaker feeds to one or more speakers.
