摘要

Summary the apparatus to determine an estimate of position for an audio source and method to determine.A first signal of microphone of a first microphone and a second signal of microphone, a second microphone.An estimate of position for an audio source in an environment of audio apparatus to determine an estimate of position for an audio source includes two microphones (M1,M2) and an acoustic element (203) that provides an acoustic effect to the sound of the sound source positions to the first microphone (M1).The acoustic effect is asymmetric in relation to an axis (201) between the microphones (M1, M2).A circuit of position (305) estimates two possible positions on different sides of the axis to the sound source in response to the times of arrivals in the microphones (M1, M2).An estimator (307) provides a measure of the acoustic effect that is indicative of a degree to which a first microphone acoustic effect signal corresponds to a characteristic expected effect CAu00fastico for sound sources on one side of the axis (201). Another circuit (309) provides the estimate of position to select between the two possible positions in response to the measured acoustic effect.The approach can resolve ambiguities in the determination of a position associated with the position determination based on time of arrival in the two microphones. 1 / 1
