Abstract
A system may comprise an input circuit, one or more filter circuits, one or more common signal detection circuits, and a controller. The input circuit may receive combined-game-and-chat audio signals generated from a mixing together of a chat audio signal and game audio signals. The filter circuit(s) may filter a first of the combined-game-and-chat audio signals to generate a first vocal-band signal and a first non-vocal-band signal, and filter a second of the combined-game-and-chat audio signals resulting in a second vocal-band signal and a second-non-vocal band signal. The common signal detection circuit(s) may detect strength of a signal component that is common to the first vocal-band signal and the second vocal-band signal, and strength of a signal component that is common to the first non-vocal-band signal and the second non-vocal-band signal. The controller may automatically control a volume setting based on one or both of the detected strengths.
