AUDIO CODER AND DECODER Russian patent published in 2019 - IPC G10L21/02 G10L19/08 G10L21/316 G10L21/364 G10L21/208 

FIELD: physics.

SUBSTANCE: invention relates to spatial audio coding means when audio information is represented by a plurality of audio objects comprising at least one dialogue object. Obtaining plurality of downmix signals, wherein the downmix signals are a downmix result of the plurality of audio objects comprising at least one object which is a dialogue. Additional information indicating coefficients which enable reconstruction of a plurality of audio objects from the plurality of downmix signals is obtained. Data are obtained which determine which of the plurality of audio objects is a dialogue. Ratios are varied using an amplification parameter and data which determine which of the plurality of audio objects is a dialogue. At least said at least one object representing dialogue is reconstructed using modified coefficients.

EFFECT: technical result is to improve the efficiency of audio coding.
