Electronic devices, methods of operating the same, and computer program products for detecting noise in a signal based on a combination of spatial correlation and time correlation
Noise, such as wind noise, for example, may be detected in an electronic device by generating first and second microphone signals. Cross correlation coefficients are determined for the first and the second microphone signals and autocorrelation coefficients are determined for the first and second microphone signals, respectively. A determination may be made with regard to the presence of a noise component in at least one of the microphone signals based on the cross correlation coefficients, the first autocorrelation coefficients, and the second autocorrelation coefficients.
