MPEG-SAOC AUDIO SIGNAL DECODER, METHOD FOR PROVIDING AN UPMIX SIGNAL REPRESENTATION USING MPEG-SAOC DECODING AND COMPUTER PROGRAM USING A TIME/FREQUENCY-DEPENDENT COMMON INTER-OBJECT-CORRELATION PARAMETER VALUE |
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. |
