FIELD: physics, acoustics.
SUBSTANCE: invention relates to processing signals in an audio frequency band. The apparatus for generating at least one output audio signal representing a superposition of two different audio objects includes a processor for processing an input audio signal to provide an object representation of the input audio signal, where that object representation can be generated by parametrically guided approximation of original objects using an object downmix signal. An object manipulator individually manipulates objects using audio object based metadata relating to the individual audio objects to obtain manipulated audio objects. The manipulated audio objects are mixed using an object mixer for finally obtaining an output audio signal having one or multi-channel signals depending on a specific rendering setup.
EFFECT: providing efficient audio signal transmission rate.
