Conferences can often have participants that sound too loud or too quiet, due to different audio levels being set by third party clients and the variation in audio levels from different headsets.

Meeting Server uses Automatic Gain Control (AGC) to adjust the audio level that it receives from individual participants in order to deliver as consistent an audio level across the conference as possible. AGC will be applied to any endpoint (physical endpoints or soft clients) connected directly to the Meeting Server, with the exception of those listed in the note below.

AGC is disabled by default, for details on enabling AGC see How do I enable Automatic Gain Control?

AGC was first introduced in version 2.8 as a beta feature, it is a fully supported feature from version 2.9.

Note: AGC will NOT be applied to the following:

- TIP calls or AVMCU (because this is a mixed audio stream),
- Skype participants connected to AVMCU, as the AVMCU controls the audio,
- distribution links between Meeting Servers (because this is a mixed audio stream),
- audio transmitted by the Meeting Server.
