Patent ID: 8238574

Claim:
A computer-implemented method for determining a time delay for time delay compensation of a microphone signal from a microphone array in a beamformer arrangement, comprising: determining in a processor, for a given time, an instantaneous estimate of a position of at least one of a wanted sound source and a direction of arrival of a signal originating from the wanted sound source; determining in the processor whether the instantaneous estimate deviates from a preset estimate of at least one of a position of the wanted sound source and a direction of arrival of a signal originating from the wanted sound source according to a predetermined criterion, wherein the predetermined criterion comprises a check whether the instantaneous estimate deviates from the preset estimate by at least a predetermined deviation threshold; if the predetermined criterion is fulfilled, setting the instantaneous estimate for the given time as the preset estimate in a memory location for the preset estimate; and determining in the processor the time delay for time delay compensation of the microphone signal based on the instantaneous estimate.
