APPARATUS FOR GENERATING OUTPUT SPATIAL MULTICHANNEL AUDIO SIGNAL

摘要

FIELD: physics, acoustics.SUBSTANCE: invention relates to means of generating an output spatial multichannel audio signal based on an input audio signal. The input audio signal is decomposed based on an input parameter to obtain a first signal component and a second signal component that are different from each other. The first signal component is rendered to obtain a first signal representation with a first semantic property and the second signal component is rendered to obtain a second signal representation with a 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: low computational costs of the decoding/rendering process.5 cl, 8 dwg
