Patent ID: 8090111

Claim:
A signal separator for determining a first output signal describing an audio content of a useful-signal source in a first microphone signal, and for determining a second output signal describing an audio content of the useful-signal source in a second microphone signal, comprising: a source separator receives the two microphone signals from two acoustic sensors located in a room to receive audio signals from signal sources located in the room and to separate audio contents of at least two signal sources, the source separator obtains a first partial signal essentially describing an audio content of a first signal source, and represents the first output signal, and so as to obtain a second partial signal essentially describing an audio content of a second signal source; the source separator adjusts parameters of a processing specification for generating the first partial signal from the microphone signals such that a distortion of the first partial signal relative to the first microphone signal is smaller than a maximum distortion, and adjusts parameters of a processing specification for generating the second partial signal from the microphone signals such that a distortion of the second partial signal relative to the second microphone signal is smaller than a maximum distortion; and a signal remover removes the second partial signal from the second microphone signal in order to obtain the second output signal, wherein the second partial signal is reduced.
