Abstract

Claims (24)

1. 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.

2. The system of claim 1 comprising a combiner circuit, wherein:

said combiner circuit is operable to a combine said first and said second of said combined-game-and-chat audio signals to generate a combined audio signal; and

said controller is operable to automatically control said volume setting based on a strength of said combined audio signal.

3. The system of claim 1 , comprising a multi-band equalizer circuit that is operable to:

apply a first gain to vocal-band frequencies of said combined-game-and-chat audio signals; and

apply a second gain to a non-vocal-band frequencies of said combined-game-and-chat audio signals.

4. The system of claim 3 , wherein said controller is operable to:

generate one or more control signals that control said first gain and said second gain, wherein a state of said one or more control signals is determined based on one or both of: said detected strength of said first signal component, and said detected strength of said second signal component.

5. The system of claim 1 , wherein:

said chat audio signal is a monophonic signal having energy substantially contained in the vocal band from approximately 300 Hz to approximately 3000 Hz;

said game audio signals comprise a left channel signal having significant energy outside of said vocal band; and

said game audio signals comprise a right channel signal having significant energy outside of said vocal band.

6. The system of claim 1 , said controller is operable to automatically control said volume setting based on a ratio of said detected strength of said first signal component to said detected strength of said second signal component.

7. The system of claim 1 , wherein said system is a headset.

8. The system of claim 1 , wherein said system is a game console.
