Claim 4:
5. A method of decoding a compressed Higher Order Ambisonics (HOA) sound representation of a sound or sound field, the method comprising:
receiving a bit stream containing the compressed HOA representation and decoding the compressed HOA representation to determine perceptually decoded signals, at least an associated gain correction exponent and at least a gain correction exception flag;
determining gain corrected signal frames based on inverse gain control processing of the perceptually decoded signals, the associated gain correction exponent, and the gain correction exception flag; and
re-distributing the gain corrected signal frames, in order to determine a frame of predominant sound signals and a frame of intermediate ambient HOA components.
