METHOD AND APPARATUS FOR WIND NOISE DETECTION |
摘要 |
A method of processing digitized microphone signal data in order to detect wind noise. First and second sets of signal samples are obtained simultaneously from two microphones. A first number of samples in the first set which are greater than a first predefined comparison threshold is determined. A second number of samples in the first set which are less than the first predefined comparison threshold is determined. A third number of samples in the second set which are greater than a second predefined comparison threshold is determined. A fourth number of samples in the second set which are less than the second predefined comparison threshold is determined. If the first number and second number differ from the third number and fourth number to an extent which exceeds a predefined detection threshold, e.g. as determined by a Chi-squared test, then an indication that wind noise is present is output. |
