Abstract
A method includes determining a first filtered signal based on an audio signal; determining a second filtered signal based on the audio signal; determining, based on the first filtered signal and the second filtered signal, a portion of the audio signal corresponding to a sharp noise; determining, based on the first filtered signal and the second filtered signal, a gain signal that, for the portion of the audio signal corresponding to the sharp noise, has a value that is smaller than a value of the gain signal for the remaining portion of the audio signal; and suppressing, based on the gain signal, the sharp noise from an amplifier input signal determined based on the audio signal.
