AN APPARATUS FOR DETERMINING A SPATIAL OUTPUT MULTI-CHANNEL AUDIO SIGNAL

摘要

AN APPARATUS (100) FOR DETERMINING A SPATIAL OUTPUT MULTI- CHANNEL AUDIO SIGNAL BASED ON AN INPUT AUDIO SIGNAL AND AN INPUT PARAMETER.THE APPARATUS (100) COMPRISES A DECOMPOSER (110) FOR DECOMPOSING THE INPUT AUDIO SIGNAL BASED ON THE INPUT PARAMETER TO OBTAIN A FIRST DECOMPOSED SIGNAL AND A SECOND DECOMPOSED SIGNAL DIFFERENT FROM EACH OTHER.FURTHERMORE, THE APPARATUS (100) COMPRISES A RENDERER (110) 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 BEING DIFFERENT FROM THE FIRST SEMANTIC PROPERTY.THE APPARATUS COMPRISES A PROCESSOR (130) FOR PROCESSING THE FIRST RENDERED SIGNAL AND THE SECOND RENDERED SIGNAL TO OBTAIN THE SPATIAL OUTPUT MULTI-CHANNEL AUDIO SIGNAL.
