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 of object signals (x 1 to x N ) comprises a downmixer (620) configured to provide one or more downmix signals in dependence on downmix coefficients (d 1 to d N ) associated with the object signals (x 1 to x N ), such that the one or more downmix signals comprise a superposition of a plurality of object signals, and a side information provider (630) configured to provide an inter-object-relationship side information (OLD, IOC) describing level differences and correlation characteristics of object signals (x 1 to x N ) and an individual-object side information describing one or more individual properties of the individual object signals (x 1 to x N ).
