Patent ID: 8811629

Claim:
A system comprising an input circuit, one or more filter circuits, one or more common signal detection circuits, and a controller, wherein: said input circuit is operable to receive combined-game-and-chat audio signals generated from a mixing together of a chat audio signal and game audio signals; said one or more filter circuits is operable to: filter a first of said combined-game-and-chat audio signals to generate a first vocal-band signal and a first non-vocal-band signal; filter a second of said combined-game-and-chat audio signals resulting in a second vocal-band signal and a second non-vocal-band signal; said one or more filter circuits is operable to: detect a strength of a first signal component that is common to said first vocal-band signal and said second vocal-band signal; detect a strength of a second signal component that is common to said first non-vocal-band signal and said second non-vocal-band signal; said controller is operable to automatically control a volume setting based on one or both of: said detected strength of said first signal component, and said detected strength of said second signal component.
