Automatic Gain Control (AGC)
Automatic Gain Control (AGC) is applicable to the hands-free operation and is used to keep audio output at nearly
a constant level by adjusting the gain of signals in some circumstances. This increases the effective user-phone
radius and helps with the intelligibility of soft-talkers.
Voice Activity Detection (VAD)
VAD can avoid unnecessary coding or transmission of silence packets in VoIP applications, saving on computation
