Generation of a downmix signal

摘要

An audio signal processing device (1) for downmixing of a first input signal ( X 1 ) and a second input signal ( X 2 ) to a downmix signal ( X D ) comprising:
a dissimilarity extractor (2) configured to receive the first input signal ( X 1 ) and the second input ( X 2 ) signal as well as to output an extracted signal ( U 2 ), which is lesser correlated with respect to the first input signal ( X 1 ) than the second input signal ( X 2 ) and
a combiner (3) configured to combine the first input signal ( X 1 ) and the extracted signal ( U 2 ) in order to obtain the downmix signal ( X D ).
