A method for generating stereo signals for at least two separate sound sources, in which a blind source separation (BSS) of at least two microphone signals is carried out for obtaining from the transmission functions of filters from a first filter device (W11(omega)). A second filter device (G11(omega)) is determined from the transmission functions of the filters with the help of the transmission function of the first filter device (W11(omega)), in which its transmission function corresponds to the quotients from a power density spectrum component (P11(omega)) of the respective sound source, and the total power density spectrum (Sx1x1) of the respective microphone signal (X1(k)) and filters of the at least two microphone signals, respectively, with at least two filters of the second filter device (G11(omega)) so for each microphone signal, two stereo signals are obtained. An independent claim is included for an acoustic signal for generating stereo signals. |
