Patent ID: 8731950

Claim:
An apparatus for providing one or more adjusted parameters for a provision of an upmix signal representation, which is an upmix audio signal representation, on the basis of a downmix signal representation, wherein several audio object signals are downmixed into the downmix signal, and an object-related parametric information, the apparatus comprising: a receiving processor for receiving one or more input parameters; a parameter adjuster configured to receive the one or more input parameters from the receiving processor and to provide, on the basis thereof, one or more adjusted parameters, wherein the parameter adjuster is configured to provide the one or more adjusted parameters in dependence on the one or more input parameters and the 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 that deviate from optimal parameters by more than a predetermined deviation; wherein the apparatus is configured to receive, as the input parameters, desired rendering parameters describing a desired intensity scaling of a plurality of audio object signals in one or more audio channels described by the upmix signal representation; and wherein the parameter adjuster is configured to provide one or more actual rendering parameters in dependence on the one or more desired rendering parameters and the object-related parametric information.
