Abstract

An audio signal decoder for providing an upmix signal representation in dependence on a downmix signal representation and an object-related parametric information includes an object separator configured to decompose the downmix signal representation, to provide a first audio information describing a first set of one or more audio objects of a first audio object type and a second audio information describing a second set of one or more audio objects of a second audio object type, in dependence on the downmix signal representation and using at least a part of the object-related parametric information.
