APPARATUS FOR GENERATING OUTPUT SPATIAL MULTICHANNEL AUDIO SIGNAL Russian patent published in 2014 - IPC H04S7/00 

FIELD: physics, acoustics.

SUBSTANCE: invention relates to means of generating an output spatial multichannel audio signal based on an input audio signal and an input parameter. The input audio signal is decomposed based on the input parameter to obtain the first signal component and the second signal component that are different from each other. The first signal component is rendered to obtain the first signal representation with the first semantic property and the second signal component is rendered to obtain the second signal representation with the second semantic property different from the first semantic property. The first and second signal representations are processed to obtain an output spatial multichannel audio signal.

EFFECT: reduced computational costs of the decoding/rendering process.
