Playback Based on Acoustic Signals

A system comprising a first playback device, a second playback device, and a network device, the first playback device comprising:

• a microphone;
• a first network interface;
• at least one first processor;
• at least one first tangible, non-transitory computer-readable medium;
• and
• first program instructions stored on the at least one first tangible, non-transitory computer-readable medium that, when executed by the at least one first processor, cause the first playback device to perform first functions comprising:
• while the second playback device is playing back first audio content, detecting, via the microphone, an acoustic signal;
• sending, to the network device via the first network interface over a digital data network, data corresponding to the detected acoustic signal;
• receiving, via the first network interface over the digital data network, one or more first commands determined by the network device based on the sent data corresponding to the detected acoustic signal;
• and
• playing back second audio content based on the one or more first commands;
• the second playback device comprising:
• a second network interface;
• at least one second processor;
• at least one second tangible, non-transitory computer-readable medium;
• and
• second program instructions stored on the at least one second tangible, non-transitory computer-readable medium that, when executed by the at least one second processor, cause the second playback device to perform second functions comprising:
• receiving, via the second network interface over the digital data network, one or more second commands determined by the network device based on the sent data corresponding to the detected acoustic signal;
• and
• after receiving the one or more second commands, stopping the playback of the first audio content based on the one or more second commands;
• and
• the network device comprising:
• a third network interface;
• at least one third processor;
• at least one third tangible, non-transitory computer-readable medium;
• and
• third program instructions stored on the at least one third tangible, non-transitory computer-readable medium that, when executed by the at least one third processor, cause the second playback device to perform third functions comprising:
• determining the one or more first commands and one or more second commands based on the sent data corresponding to the detected acoustic signal;
• sending, to the first playback device via the second network interface over the digital data network, the one or more first commands;
• and
• sending, to the second playback device via the second network interface over the digital data network, the one or more second commands.

A system comprising a first playback device, a second playback device, and a controller device, the first playback device comprising:

• a microphone;
• a first network interface;
• at least one first processor;
• at least one first tangible, non-transitory computer-readable medium;
• and
• first program instructions stored on the at least one first tangible, non-transitory computer-readable medium that, when executed by the at least one first processor, cause the first playback device to perform first functions comprising:
• while the second playback device is playing back first audio content, detecting, via the microphone, an acoustic signal;
• sending, to a network device via the first network interface over a digital data network, data corresponding to the detected acoustic signal;
• receiving, via the first network interface over the digital data network, one or more first commands determined by the network device based on the sent data corresponding to the detected acoustic signal;
• and
• playing back second audio content based on the one or more first commands;
• the second playback device comprising:
• a second network interface;
• at least one second processor;
• at least one second tangible, non-transitory computer-readable medium;
• and
• second program instructions stored on the at least one second tangible, non-transitory computer-readable medium that, when executed by the at least one second processor, cause the second playback device to perform second functions comprising:
• receiving, via the second network interface over the digital data network, one or more second commands determined by the network device based on the sent data corresponding to the detected acoustic signal;
• and
• after receiving the one or more second commands, stopping the playback of the first audio content based on the one or more second commands;
• and
• the controller device comprising:
• a third network interface;
• at least one third processor;
• at least one third tangible, non-transitory computer-readable medium;
• and
• third program instructions stored on the at least one third tangible, non-transitory computer-readable medium that, when executed by the at least one third processor, cause the controller device to perform third functions comprising:
• sending, via the third network interface to the second playback device, one or more second instructions to cease playback of the second audio content.
