Abstract:
A signal processing unit calculates a first difference in time of arrival of sound from a sound source to a first and to a second microphone comprising a microphone array and calculates a second difference in time of arrival, which is the difference between the first difference in time of arrival and an actual time, of arrival, and determines the position of the sound source based on the sum of the first difference in time of arrival and the second difference in time of arrival.

Claim (Index 35):
A method for calculating the direction of arrival of sound with respect to microphones in a microphone array, comprising:\n calculating a first difference in time of arrival value of sound from a sound source to a first and to a second one of a plurality of microphones comprising the microphone array, the first difference in time of arrival being an integer multiple of one sound inter-sample time, and calculating a second difference in time of arrival value of the sound from the sound source to a first and to a second one of the plurality of the microphones, the second difference in time of arrival being a fractional value representing a difference between the first difference in time of arrival and an actual difference in time of arrival of the sound; adding the first and the second differences in time of arrival to determine a value of the actual difference in time of arrival of the sound; and determining the direction of arrival of the sound with respect to the first and the second microphones in the microphone array based on the value of the actual difference in time of arrival of the sound between the first and the second ones of the plurality of microphones.
