Method for decoding distorted radio signals in multichannel audio signals

Abstract

The present invention relates to a method for decoding multi-channel audio broadcasts, in particular two-channel stereo audio broadcasts, with a respective payload per channel, wherein for each of the payloads transmitted frequency spectrum of a signal source by different temporal occurrence and different levels in the different channels spatial impression or a location information for the corresponding signal source is generated. In this case, during the reception of the multichannel audio program in time segments in which the reception is so disturbed that a direct multi-channel reproduction is no longer possible,
