Abstract:
An apparatus for reproducing an audio signal includes a first reproducer configured to reproduce a first portion of the audio signal in a first frequency band based on the first data. A provider is configured to provide a patch signal in a second frequency band, wherein the patch signal is at least partially uncorrelated with respect to the first portion of the audio signal or is at least partially a decorrelated version of the first portion of the audio signal, which has been shifted to the second frequency band. A second reproducer is configured to reproduce a second portion of the audio signal in the second frequency band based on second data and the patch signal. A combiner is configured to combine the reproduced first portion of the audio signal and the patch signal.
