Abstract
In at least one embodiment, an audio system is provided. The audio system includes one or more microphones and at least one controller. The one or more microphones are positioned within a listening space to provide a captured audio input signal. The at least one controller is programmed to receive the captured audio input signal and to receive a first signal indicative of an audio level in the listening space. The at least one controller determines a gain amount based on the audio level and to adjusts the captured audio input signal.
Claims20
An audio system comprising:
- at least one microphone positioned in a listening space to provide a captured audio input signal;
- at least one controller programmed to:
- receive the captured audio input signal;
- receive a volume control signal indicative of a volume setting;
- receive a media input signal;
- determine a media level based on the media input signal and the volume control signal;
- determine a first gain level based on the volume setting;
- determine a second gain level based on the level of audio;
- determine a total microphone gain level based on the first gain level and the second gain level;
- and
- adjust the captured audio input signal based on the total microphone gain level.
A computer-program product embodied in a non-transitory computer readable medium that is programmed and executable by one or more controllers to adjust audio, the computer-program product comprising instructions for:
- receiving a captured audio input signal from one or more microphones positioned in a listening space;
- receiving a volume control signal indicative of a volume setting;
- receiving a media input signal indicative of a level of audio;
- performing one or more of:
- determining a gain level based on the level of audio and a volume setting;
- and
- applying the gain level to the captured audio input signal.
An audio system comprising:
- at least one microphone positioned in a listening space to provide a captured audio input signal;
- at least one controller programmed to:
- receive the captured audio input signal;
- receive a media input signal indicative of a level of audio in real-time;
- determine a first gain level based on the level of audio;
- and
- dynamically adjust the captured audio input signal in real-time based on the first gain level.
