Abstract:
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.
