APPARATUS FOR PROVIDING ONE OR MORE ADJUSTED PARAMETERS FOR PROVISION OF UPMIX SIGNAL REPRESENTATION BASED ON DOWNMIX SIGNAL REPRESENTATION, AUDIO SIGNAL DECODER, AUDIO SIGNAL TRANSCODER, AUDIO SIGNAL ENCODER, AUDIO BITSTREAM, METHOD AND COMPUTER PROGRAM USING OBJECT-RELATED PARAMETRIC INFORMATION

摘要

PROBLEM TO BE SOLVED: To provide one or more adjusted parameters for a provision of an upmix signal representation on the basis of a downmix signal representation and object-related parametric information.SOLUTION: An apparatus for providing one or more adjusted parameters for a provision of an upmix signal representation comprises a parameter adjuster. The parameter adjuster is configured to receive one or more input parameters and supply one or more adjusted parameters on the basis of the one or more input parameters. The parameter adjuster is configured to provide one or more adjusted parameters in dependence on the one or more input parameters and object-related parametric information, such that a distortion of the upmix signal representation caused by the use of non-optimal parameters is reduced at least for input parameters deviating from optimal parameters by more than a predetermined deviation.
