Claim 10:
11. A method of processing a compressed representation of a spatial audio signal for generating a reconstructed representation of the spatial audio signal, wherein the compressed representation comprises a channel-based audio signal with a predefined number of channels and metadata, the metadata comprising direction information and energy information, with the direction information comprising indications of directions of arrival of one or more audio elements in an audio scene and the energy information comprising, for at least one frequency subband, respective indications of signal power associated with the directions of arrival, the method comprising:
generating audio signals of the one or more audio elements based on the channel-based audio signal, the direction information, and the energy information; and
generating a residual audio signal from which the one or more audio elements are substantially absent, based on the channel-based audio signal, the direction information, and the energy information.
