Patent ID: 8194881

Claim:
A system, comprising: a first transducer with a first directivity index and configured to detect a first audio signal, where the first directivity index is non-zero and the first audio signal has a first power level; a second transducer with a second directivity index and configured to detect a second audio signal, where the second directivity index is less than the first directivity index and the second audio signal has a second power level; to a detector configured to output a detection signal based on a comparison of the first power level and the second power level, the detection signal indicating presence of wind noise if the second power level is less than the first power level by a predetermined value, and indicating absence of wind noise if the second power level is not less than the first power level by the predetermined value; and a signal processor configured to output an output signal from the first audio signal, the second audio signal, or combinations thereof, based on the detection signal where the output signal is generated from a combination of the first audio signal and the second audio signal if the detection signal indicates the presence of wind noise or the detection signal is not output, the combination comprising a portion of the first audio signal above a predetermined frequency and a portion of the second audio signal below the predetermined frequency.
