DEVICE FOR OPTIMISING ONE OR MORE UPMIXING SIGNAL PRESENTATION PARAMETERS BASED ON DOWNMIXING SIGNAL PRESENTATION, AUDIO SIGNAL DECODER, AUDIO SIGNAL TRANSCODER, AUDIO SIGNAL ENCODER, AUDIO BITSTREAM, METHOD AND COMPUTER PROGRAM USING OBJECT-ORIENTED PARAMETRIC INFORMATION

摘要

FIELD: information technology.SUBSTANCE: device includes a parameter regulator. The parameter regulator receives one or more input parameters based on which it generates one or more adjusted parameters. The parameter regulator generates one or more adjusted parameters using one or more input parameters and object-oriented parametric information such that distortion of presentation of an upmixing signal caused by the use of non-optimum parameters, is reduced for at least input parameters deviating from optimum parameters by a value greater than a given deviation limit.EFFECT: reducing acoustic distortions when upmixing an audio signal.26 cl, 12 dwg
