METHOD AND ELECTRONIC DEVICE 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.
