Orientation-based playback device microphone selection

A non-transitory computer-readable medium, wherein the non-transitory computer-readable medium is provisioned with program instructions that, when executed by at least one processor, cause a playback device to:

• detect, via a set of microphones of the playback device, a sound input;
• determine a microphone response of the set of microphones based on the detected sound input;
• access a data storage comprising a set of microphone training responses, wherein each respective microphone training response of the set of microphone training responses corresponds to a respective position of a sound source relative to the playback device;
• compare the determined microphone response to the set of microphone training responses;
• based on the comparison, identify a particular microphone training response of the set of microphone training responses that correlates with the determined microphone response;
• determine a location of a source of the detected sound input based on the identified particular microphone training response;
• adjust a directional focus of the set of microphones based on the determined location of the source of the detected sound input;
• and
• after adjusting the directional focus of the set of microphones, capture additional sound input using the set of microphones.

A method carried out by a playback device, the method comprising:

• detecting, via a set of microphones of the playback device, a sound input;
• determining a microphone response of the set of microphones based on the detected sound input;
• accessing a data storage comprising a set of microphone training responses, wherein each respective microphone training response of the set of microphone training responses corresponds to a respective position of a sound source relative to the playback device;
• comparing the determined microphone response to the set of microphone training responses;
• based on the comparison, identifying a particular microphone training response of the set of microphone training responses that correlates with the determined microphone response;
• determining a location of a source of the detected sound input based on the identified particular microphone training response;
• adjusting a directional focus of the set of microphones based on the determined location of the source of the detected sound input;
• and
• after adjusting the directional focus of the set of microphones, capturing additional sound input using the set of microphones.
