Automatic Level Control (ALC) /Automatic Gain Control (AGC)

Automatic Level Control (ALC) /Automatic Gain Control (AGC): A circuit inserted in the preamplification stage of the recorder that quickly and automatically adjusts the recording levels to adapt to changes in the audio source signal. This function will work instead of the manual level adjustment capability and will boost a lower end signal as well as protect a hotter signal from distorting. Not usually associated with professional-level recording as the recordings tend to be noisy. This setting is often included on video cameras as well and, like for audio, should be switched to manual recording for best results. [ Audio Glossary ] [ Video Glossary ]
