In one embodiment, a method includes extracting, by a processor, components from an audio signal to generate a modulating signal. The audio signal is generated by an endpoint operable to capture audio proximate the endpoint. The method also includes filtering, by the processor, the audio signal to generate a band-limited audio signal. The method also includes modulating, by the processor, the band-limited audio signal by the modulating signal to generate an enhancement signal. The method also includes combining, by the processor, the audio signal and the enhancement signal to generate an enhanced audio signal.
