A long term signal level of an audio signal is computed at a local device, wherein the audio signal was transmitted from a remote device and received by the local device. An automatic gain control (AGC) gain is computed at the local device based on the long term signal level. A noise factor indicative of a level of ambient noise at the local device is computed at the local device. A dynamic range compression (DRC) gain is computed at the local device based on the noise factor. An amplitude of the audio signal is adjusted at the local device based on the AGC gain and the DRC gain.
