A method of processing an audio signal in order to overcome background noise extraneous to the audio signal. The method includes comparing a measure of the audio signal in a frequency component of the audio signal to a measure of the noise in a frequency component of the background noise, determining a gain responsive to the comparison and amplifying at least a portion of the audio signal, including at least one frequency segment not included in the frequency component of the audio signal, by the determined gain. |
