An image capture device may include a microphone, a vibration sensor, and a processor. The microphone may obtain a microphone signal that includes an acoustic signal portion and a mechanical noise portion. The vibration sensor may obtain a vibration signal. The processor may upsample the vibration signal. The processor may determine a correlation value. The correlation value may be based on the microphone signal, the upsampled vibration signal, or both. The processor may determine filter coefficients. The filter coefficients may be determined on a condition that the correlation value is above a threshold. The filter coefficient may be based on the upsampled vibration signal. The processor may filter the vibration signal based on the filter coefficients to remove the mechanical noise portion and obtain a processed microphone signal. The processor may output the processed microphone signal.
