摘要
A method and an apparatus for controlling gain in a multi-audio channel system as well as a voice processing system are disclosed. The method includes: judging whether signals on any audio channels are similar or correlated; sorting audio channels of similar or correlated signals into one group if the similar or correlated signals exist on the audio channels, and using the same Automatic Gain Control (AGC) unit to process signals of this group of audio channels; and using different AGC units to process other non-similar or non-correlated signals on audio channels. The gain control apparatus includes: a judging unit, a grouping unit, a control processing unit, and at least two AGC units. Therefore, in a multi-audio channel communication, the perception of the sound locations of similar or correlated audio channels is not damaged, and the non-similar or non-correlated audio channels doe not interfere with each other.
