DEVICE AND METHODS FOR ADAPTATION OF AUDIO INFORMATION AT SPATIAL ENCODING OF AUDIO OBJECTS Russian patent published in 2017 - IPC G10L19/08 G10L19/16 

FIELD: acoustics.

SUBSTANCE: invention relates to means for adaptation of input audio information encoding one or more audio objects. Input audio information includes two or more input downmix audio channels and additionally contains input parametric supplementary information. Adapted audio information includes one or more adapted downmix audio channels and additionally contains adapted parametric supplementary information. Device contains a downmix signal modifier for adaptation, depending on the adaptation information, of two or more input downmix audio channels to obtain one or more adapted downmix audio channels. Besides, the device comprises a means to adapt parametric supplementary information for adaptation, depending on the adaptation information, of the input parametric supplementary information to obtain the adapted parametric supplementary information.

EFFECT: technical result is improvement of efficiency of adaptation of audio information to a specific target application scenario.
