RENDERER CONTROLLED SPATIAL UPMIX Russian patent published in 2018 - IPC H04S5/00 H04S7/00 G10L19/08 

FIELD: data processing.

SUBSTANCE: invention relates to spatial upmix means. Processor output signal is generated based on a processor input signal. Number of output channels of the processor output signal is higher than a number of input channels of the processor input signal. Each of the one or more processors comprises a decorrelator and a mixer. Core decoder output signal having a plurality of channels comprises the processor output signal. Core decoder output signal is suitable for a reference loudspeaker setup. Core decoder output signal is converted into an output audio signal, which is suitable for a target loudspeaker setup. At least one or more processors are controlled in such way that the decorrelator of the processor may be controlled independently from the mixer of the processor. One of the decorrelators of the one or more processors is controlled depending on the target loudspeaker setup.

EFFECT: technical result consists in improvement of efficiency of coding.
