Patent ID: 8553891

Claim:
An audio decoder for generating a first audio output channel and a second audio output channel in response to a parametric audio representation including a set of signal parameters and a spatial image parameter, the decoder comprising: a parameter processing unit configured to generate a first set of parameters and a second set of parameters based on the set of signal parameters, wherein the parameter processing unit is configured to generate a difference between the first sets of parameters and the second sets of parameters based on the spatial image parameter; a first signal synthesizer configured to generate the first audio output channel according to the first set of parameters; a second signal synthesizer configured to generate the second audio output channel according to the second set of parameters; and a delay unit configured to generate a delayed version of at least one signal parameter of the set of signal parameters, wherein the parameter processing unit generates the first set of parameters and the second set of parameters based on the at least one signal parameter of the set of signal parameters and the delayed version of the at least one signal parameter.
