Abstract (en)
[origin: DE10344638A1] The audio signal processing circuit (12) has a large number of input channels (16) carrying separate signals (Ek1-Ekm). The circuit may be a WFS (Wave Field Synthesis) rendering unit. It has a large number of output channels (14) carrying loudspeaker signals (LS1- LSn). A display device (18) provides the inputs for the audio signal processing circuit. Temporally non- overlapping audio objects are allocated to the same input channel. The input for the display device comes from the device generating the audio scene (10) with separate audio objects.
