    摘要: An audio signal decoder for providing an upmix signal representation on the basis of a downmix signal representation and an object-related parametric information and in dependence on a rendering information comprises an object parameter determinator. The object parameter determinator is configured to obtain inter-object-correlation values for a plurality of pairs of audio objects. The object parameter determinator is configured to evaluate a bitstream signaling parameter in order to decide whether to evaluate individual inter-object-correlation bitstream parameter values to obtain inter-object-correlation values for a plurality of pairs of related audio objects, or to obtain inter-object-correlation values for a plurality of pairs of related audio objects using a common inter-object-correlation bitstream parameter value. The audio signal decoder also comprises a signal processor configured to obtain the upmix signal representation on the basis of the downmix signal representation and using the inter-object-correlation values for a plurality of pairs of related objects and the rendering information.

    摘要: An audio processor for providing a plurality of loudspeaker signals, or loudspeaker feeds, on the basis of a plurality of input signals, like channeled signals and/or object signals. The audio processor is configured to obtain an information about the position of a listener. The audio processor is further configured to obtain an information about the position of a plurality of loudspeakers, or sound transducers, which may be placed within the same containment, e.g. a soundbar. The audio processor is further configured to dynamically adapt an allocation of objects and/or channel objects and/or adapted signals, like adapted channel signals, derived from the input signals, like channel signals or channel objects, or like upmixed or downmixed signals, to loudspeakers. The adaptation of the location depends on the information about the position of the listener and on the information about the positions of the loudspeakers. In other words, the audio processor decides which loudspeakers should be used in the rendering of the different channel objects or adapted signals. The audio signal processor is further configured to render the objects and/or the channel objects and/or the adapted signals derived from the input signals, in dependence on the information about the position of the listener, on the information about positions of the loudspeakers and in dependence on the allocation, in order to obtain the loudspeaker signals, such that a rendered sound follows a listener.
