Abstract
In one implementation, an apparatus includes an audio detection circuit, a central processor, and the switch. The audio detection circuit is configured to determine whether audio is present in an input signal and generate an audio presence indicator indicative of the audio. The central processor is configured to receive the audio presence indicator and a mute command. The central processor generates a switch command based on the mute command. The switch is configured to block the input signal from a digital signal processor in response to the switch command. The central processor generates a dynamic mute message that indicates audio is detected while a mute command is active.
Claims20
An apparatus comprising:
- an audio detection circuit configured to determine whether audio is present in an input signal and generate an audio presence indicator indicative of the audio;
- a central processor configured to receive the audio presence indicator and a mute command, wherein the central processor generates a switch signal based on the mute command and generates a dynamic mute signal based on the audio presence indicator and the mute command;
- and
- a switch configured to block the input signal from a digital signal processor in response to the switch signal.
A method comprising:
- generating an audio presence indicator indicative of whether audio is present in an input signal;
- receiving a mute command from a user input;
- generating, at a main processor, a switch command in response to the the mute command;
- generating, at the main processor, a dynamic mute message in response to the audio presence indicator and the mute command;
- and
- blocking the input signal from a digital signal processor in response to the switch command.
An apparatus comprising:
- a processor;
- and
- a memory comprising one or more instructions executable by the processor to perform:
- generating an audio presence indicator indicative of whether audio is present in an input signal;
- generating a switch command in response to a mute command, wherein the switch command prevents the input signal from being received at a digital signal processor;
- and
- generating a dynamic mute message in response to the audio presence indicator and the mute command.
