CODER, DECODER, SYSTEM AND METHOD USING CONCEPT OF BALANCE FOR PARAMETRIC CODING OF AUDIO OBJECTS Russian patent published in 2017 - IPC G10L19/08 H04S3/00 

FIELD: physics.

SUBSTANCE: decoder comprises a parametric decoding unit for generating a plurality of first estimated audio object signals by upmixing three or more downmix signals. The parametric decoding unit is configured to upmix the three or more downmix signals depending on the parametric side information indicating information about the plurality of original audio object signals. Moreover, the decoder comprises a residue processing unit for generating a plurality of second estimated audio object signals by modifying one or more of the first estimated audio object signals. The residual processing unit is configured to modify mentioned one or more of mentioned first estimated audio object signals depending on one or more residual signals.

EFFECT: increasing the coding efficiency.
