1. A method of decoding a compressed Higher Order Ambisonics (HOA) representation of a sound or a soundfield, the method comprising:
receiving a layered bit stream comprising the compressed HOA representation, wherein the compressed HOA representation comprises a base layer and an enhancement layer;
decoding the compressed HOA representation from the layered bit stream to obtain a sequence of decoded HOA representations,
wherein the base layer comprises a first subset of the sequence of decoded HOA representations that corresponds to a first set of indices, and
wherein, for each index in the first set of indices, a respective decoded HOA representation in the first subset comprises only a corresponding ambient HOA component.
