FIELD: coding and decoding of audio signals.
SUBSTANCE: invention relates to means for coding and decoding immersive audio signals. The bitstream contains a sequence of superframes for a sequence of frames of an immersive audio signal. Repeated order for the superframe sequence: insert encoded audio data for two or more frames of one or more downmix channel signals obtained from the immersive audio signal into the data fields of the superframe; and inserting metadata for recreating two or more frames of the immersive audio signal from the encoded audio data in the metadata field of the superframe.
EFFECT: increasing the efficiency of coding immersive audio signals.
