Abstract
A decoder for generating an audio output signal having one or more audio output channels from a downmix signal having one or more downmix channels is provided. The downmix signal encodes one or more audio object signals. The decoder has a threshold determiner for determining a threshold value depending on a signal energy and/or a noise energy of at least one of the of or more audio object signals and/or depending on a signal energy and/or a noise energy of at least one of the one or more downmix channels. Moreover, the decoder has a processing unit for generating the one or more audio output channels from the one or more downmix channels depending on the threshold value, by computing eigenvalues of a downmix channel cross correlation matrix, wherein each eigenvalue except largest eigenvalue is compared to the threshold value, and omitted if they are smaller.
