FIELD: computer equipment.
SUBSTANCE: invention relates to means for encoding and decoding audio data. Receiving both encoded audio data obtained by encoding an audio signal from an audio object in a frame of a given period of time, and a plurality of metadata for said frame. Encoded audio data is decoded. Performing display based on audio signal obtained as a result of decoding, and metadata. Each metadata from the plurality of metadata is metadata for a plurality of samples in the audio signal frame, up to a given number of samples in the frame. Metadata comprises location information indicating an audio object position. Metadata comprises metadata for use in interpolation processing of gain factors for audio signal samples, wherein said gain factors are calculated based on said metadata.
EFFECT: technical result consists in improved efficiency of coding.
