Abstract:
1. Apparatus for generating at least one audio output signal representing a superposition of at least two different audio objects, comprising: a processor for processing an audio input signal to provide an object representation of the audio input signal, in which the at least two different audio objects are separated from each other, the at least two different audio objects are available as separate audio object signals, and the at least two different audio objects are manipulatable independently from each other; an object manipulator for manipulating the audio object signal or a mixed audio object signal of at least one audio object based on audio object based metadata referring to the at least one audio object to obtain a manipulated audio object signal or a manipulated mixed audio object signal for the at least one audio object; and an object mixer for mixing the object representation by combining the manipulated audio object with an unmodified audio object or with a manipulated different audio object manipulated in a different way as the at least one audio object; wherein the apparatus for generating at least one audio output signal representing a superposition of at least two different audio objects is adapted to generate m output signals, m being an integer greater than 1; the processor is operative to provide an object representation having k audio objects, k being an integer and greater than m; the object manipulator is adapted to manipulate at least two objects different from each other based on metadata associated with at least one object of the at least two objects; and the object mixer is operative to combine the manipulated audio signals of the at least two different objects to obtain the m output signals so that each output signal is influenced by the manipulated audio signals of the at least two different objects.
