44 ENHANCED CODING AND PARAMETER REPRESENTATION OF MULTICHANNEL DOWNMDCED OBJECT CODING 5 ABSTRACT AN AUDIO OBJECT CODER FOR GENERATING AN ENCODED OL@JECT SIGNAL USING A PLURAFITY OF AUDIO OBJECTS INCLUDES A DOWNMIX INFORMATION GENERATOR FOR GENERATING DOWNMIX INFORMATION INDICATING A DIS- TRIBUTION OF THE PLURALITY OF AUDIO OBJECTS INTO AT LEAST TWO DOWNRNIX CHANNELS, AN AUDIO OBJECT PA- I 0 RAMETER GENERATOR FOR GENERATING OBJECT PARAMETERS FOR THE AUDIO OBJECTS, AND AN OUTPUT INTERFACE FOR GENERATING THE IMPORTED AUDIO OUTPUT SIGNAL USING THE DOWNMIX INFORMATION AND THE OBJECT PA- RAMETERS. AN AUDIO SVNTHESIZER USES THE DOWNMIX INFORMATION FOR GENERATING OUTPUT DATA USABLE FOR CREATING A PLURA.L0 OF OUTPUT CHANNELS OF THE PREDEFINED AUDIO OUTPUT CONFIGUMTION. FIE. 9
