APPARATUS FOR GENERATING OUTPUT SPATIAL MULTICHANNEL AUDIO SIGNAL Russian patent published in 2014 - IPC G10L19/08 

FIELD: physics.

SUBSTANCE: apparatus (100) for generating an output spatial multichannel audio signal is based on an input audio signal and an input parameter. The apparatus (100) includes a decomposer (110) for breaking down the input audio signal based on the input parameter to obtain a first signal component and a second signal component, different from each other. The apparatus (100) also consists of a rendering unit (110) for rendering the first signal component to obtain a first rendered signal with a first semantic property and for rendering the second signal component to obtain a second rendered signal with a second semantic property different from the first semantic property. The apparatus (100) includes a processor (130) for processing the first and second rendered signals to obtain an output spatial multichannel audio signal.

EFFECT: providing high quality of perception when processing signals which create a background.
