System and method for microphone gain adjust based on speaker orientation
First Claim
Patent Images
1. A digital processor programmed to undertake logic for dynamically establishing a gain of an audio system, the logic being stored on a computer readable medium and executable by the digital processor to implement a method including:
- receiving a video stream representative of at least one person and at least one microphone;
deriving person-microphone position signals using the video stream;
using at least some of the person-microphone position signals, generating audio gain adjust signals for input thereof to the audio system;
recording at least one calibration person-microohone position signal;
recording at least one calibration audio level contemporaneously with the calibratiotperson-microphone position signal;
using the calibration signal and calibration level, generating at least one mapping correlating head orientations to respective gain adjust percentages; and
at least in part using the gain adjust percentages, establishing an audio gain of the audio system.

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.
