WIND NOISE REDUCTION, FLEXIBLE BEAMFORMING, AND DIRECTION OF ARRIVAL ESTIMATION BY MICROPHONE PLACEMENT
摘要:
An image capture device includes a housing, a processor, and three or more microphones. The housing includes a forward wall including a sensor, a rearward wall located opposite the forward wall, and a top wall connecting the forward wall and the rearward wall. The three or more microphones are configured to capture sound. The three or more microphones include a first microphone, a second microphone, and a third microphone. The processor is configured to receive the sound from the three or more microphones and to estimate a direction of arrival, reduce or remove wind noise, perform beamforming, or a combination thereof. The first microphone is located on or within the forward wall, the second microphone is located on or within the top wall, and the third microphone is located on or within the top wall and spaced apart from the second microphone.
