Title: CONCEPT FOR GENERATING A DOWNMIX SIGNAL
Abstract:
An audio signal processing device (1) for downmixing of a first input signal (X1) and a second input signal (X2) to a downmix signal (XD) comprising: a dissimilarity extractor (2) configured to receive the first input signal (X1) and the second input (X2) signal as well as to output an extracted signal (Û2), which is lesser correlated with respect to the first input signal (X1) than the second input signal (X2) and a combiner (3) configured to combine the first input signal (X1) and the extracted signal (Û2) in order to obtain the downmix signal (XD).
