Automatic volume control for combined game and chat audio
View Patent ↗A system comprising audio processing circuitry is provided. The audio processing circuitry is operable to receive combined-game-and-chat audio signals generated from a mixing together of a chat audio signal and game audio signals. The audio processing circuitry is operable to process the combined-game-and-chat audio signals to detect strength of a chat component of the combined-game-and-chat audio signals and strength of a game component of the combined-game-and-chat audio signals. The audio processing circuitry is operable to automatically control a volume setting based on one or both of: the detected strength of the chat component, and the detected strength of the game component. The combined-game-and-chat audio signals may comprise a left channel signal and a right channel signal. The processing of the combined-game-and-chat audio signals may comprise measuring strength of a vocal-band signal component that is common to the left channel signal and the right channel signal.
1. A method comprising
in a headset comprising a game/chat distinguisher and a volume control circuit:
receiving combined-game-and-chat audio signals generated from a mixing together of a chat audio signal and game audio signals;
processing, using said game/chat distinguisher, said combined-game-and-chat audio signals to detect strength of a chat component of said combined-game-and-chat audio signals and strength of a game component of said combined-game-and-chat audio signals; and
automatically controlling, using said volume circuit, a volume setting based on one or both of: said detected strength of said chat component, and said detected strength of said game component.
2. The method of claim 1 , wherein:
said combined-game-and-chat audio signals comprise a left channel signal and a right channel signal; and
said processing of said combined-game-and-chat audio signals comprises a measurement of strength of a vocal-band signal component that is common to said left channel signal and said right channel signal.
3. A system comprising:
audio processing circuitry comprising a game/chat distinguisher, an envelope detector, and a volume control circuit, said audio processing circuity being operable to:
receive, at said game/chat distinguisher, combined-game-and-chat audio signals generated from a mixing together of a chat audio signal and game audio signals;
process, via said envelope detector and said game/chat distinguisher, said combined-game-and-chat audio signals to detect strength of a chat component of said combined-game-and-chat audio signals and strength of a game component of said combined-game-and-chat audio signals; and
automatically control, via said volume control circuit, a volume setting based on one or both of: said detected strength of said chat component, and said detected strength of said game component.
4. The system of claim 3 , wherein:
said combined-game-and-chat audio signals comprise a left channel signal and a right channel signal; and
said processing of said combined-game-and-chat audio signals comprises a measurement, by said game/chat distinguisher, of strength of a vocal-band signal component that is common to said left channel signal and said right channel signal.
5. The system of claim 4 , wherein said processing of said combined-game-and-chat audio signals comprises a measurement, by said game/chat distinguisher, of strength of a non-vocal-band signal component that is common to said left channel signal and said right channel signal.
6. The system of claim 5 , wherein said processing of said combined-game-and-chat audio signals comprises:
a combining, by a combiner circuit of said audio processing circuitry, of said left channel audio signal and said right channel audio signal resulting in a combined audio signal; and
measuring, by said game/chat distinguisher, strength of said combined audio signal over vocal and non-vocal bands.
7. The system of claim 3 , wherein said audio processing circuitry is operable to:
apply, by a gain circuit of said volume control circuit, a first gain to vocal-band frequencies of said combined-game-and-chat audio signals; and
apply, by said gain circuit, a second gain to a non-vocal-band frequencies of said combined-game-and-chat audio signals.
8. The system of claim 7 , wherein said volume control circuit of said audio processing circuitry 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 automatically controlled in response to one or both of: said detected strength of said chat component, and said detected strength of said game component.
9. The system of claim 3 , wherein said volume control circuit of said audio processing circuitry is operable to automatically control said volume setting based on a ratio of said detected strength of said chat component to said detected strength of said game component.
10. The system of claim 3 , wherein said audio processing circuitry is in a headset.
11. The system of claim 3 , wherein said audio processing circuitry is in a game console.
