ABSTRACT:
A signal processing system is provided which receives signals from a number of different sensors which are representative of signals generated from a plurality of sources. The sensed signals are processed to determine the relative position of each of the sources relative to the sensors. This information is then used to separate the signals from each of the sources. The system can be used, for example, to separate the speech signal generated from a number of users in a meeting.
