ADAU1761 -- Beamforming with Wind Noise Reduction

Question asked by keddy on Feb 23, 2016



I got one customer doing BT Handsfree in the car environment. They have encountered one issue whereby the BT handsfree module is mounted below the air-con blower in one of the car model. They use 2 Mics and our adaptive beamforming algo with ADAU1761 to do the directional capturing of the voice. But for this particular car model, there is constant wind noise whenever the air-con louver is pointing down. I am wondering is there any way we can use the WNR algo to implement in ADAU1761 together with Beamforming to achieve the best result. Can you help to advice?



Thanks and Best Regards,
