Abstract: A radio includes a first tuner and a second tuner. A processor compares a first perceivable volume level of a station tuned by the first tuner to at least one second perceivable volume level of at least one background station tuned by the second tuner. The processor enables automatic volume knob changes using a pre-calibrated lookup table that associates a volume step of the volume knob with a difference between the first perceivable volume level and the second perceivable volume level.

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.

Abstract: An automatic gain control derives the gain from the distance between the sound source and the microphone. The distance-based automatic gain control normalizes signal level changes caused by a speaker not maintaining a constant distance with respect to the microphone. Also, a proximity-effect compensation that derives the adaptive filter from the distance between the sound source and the microphone. The proximity-effect compensation corrects frequency response changes due to undesired proximity-effect variations. Determination of the distance between a sound source and a microphone permits accurate compensation for both frequency response changes and distance-related signal level changes.
