摘要：An audio signal encoder (600) for providing a downmix signal representation(614) and an object-related parametric information (616) on the basis of a plurality ofobject signals (x 1 to x N ) comprises a downmixer (620) configured to provide one ormore downmix signals in dependence on downmix coefficients (d 1 to d N ) associatedwith the object signals (x 1 to x N ), such that the one or more downmix signals comprise asuperposition of a plurality of object signals, and a side information provider (630)configured to provide an inter-object-relationship side information (OLD, IOC) describinglevel differences and correlation characteristics of object signals (x 1 to x N ) and anindividual-object side information describing one or more individual properties of theindividual object signals (x 1 to x N ).
