APPARATUS FOR DETERMINING SPATIAL OUTPUT MULTI-CHANNEL AUDIO SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for determining a spatial output multi-channel audio signal based on an input audio signal and an input parameter.

SOLUTION: An apparatus 100 includes a decomposer 110 for decomposing an input audio signal based on an input parameter to obtain a first decomposed signal and a second decomposed signal which are different from each other. Furthermore, the apparatus includes a renderer 120 for rendering the first decomposed signal to obtain a first rendered signal having a first semantic property and for rendering the second decomposed signal to obtain a second rendered signal having a second semantic property which is different from the first semantic property. The apparatus includes a processor 130 for processing the first rendered signal and the second rendered signal to obtain a spatial output multi-channel audio signal.
