Abstract:
1. Apparatus for generating at least one audio output signal representing a superposition of at least two different audio objects, the at least two different audio objects comprising a first audio object and a second audio object, the apparatus comprising: a processor arranged to process an audio input signal, the audio input signal being an object downmix comprising the first audio object and the second audio object, to provide an object representation of the audio input signal, in which the first audio object and the second audio object are separated from each other, in which the first audio object and the second audio object are available as a first audio object signal and a separate second audio object signal, and in which the first audio object signal and the second audio object signal are manipulatable independently from each other; an object manipulator arranged to manipulate the first audio object signal based on audio object based metadata referring to the first audio object to obtain a manipulated first audio object signal for the first audio object; and an object mixer arranged to combine the manipulated first audio object signal with the second audio object signal, the second audio object signal not being manipulated by the object manipulator or arranged to combine the manipulated first audio object signal with a manipulated second audio object signal, the manipulated second audio object signal being manipulated by the object manipulator based on audio object based metadata referring to the second audio object in a different way as compared to the manipulated first audio object signal.
