Electronic devices, methods, and computer program products for detecting noise in a signal based on autocorrelation coefficient gradients |
摘要 |
An electronic device can be operated to detect noise, such as wind noise. A microphone signal is generated by a microphone. Autocorrelation coefficients are determined based on the microphone signal. Gradient values are determined from the autocorrelation coefficients. The presence of a noise component in the microphone signal is determined based on the gradient values |
