ABSTRACT:
A system and method for automatically adjusting the gain of an audio system as a speaker's head moves relative to a microphone includes using a video of the speaker to determine an orientation of the speaker's head relative to the microphone and, hence, a gain adjust signal. The gain adjust signal is then applied to the audio system that is associated with the microphone to dynamically and continuously adjust the gain the audio system.
