Calibration of Audio Playback Devices

A method comprising:

• outputting first audio content by a speaker of an audio playback device;
• receiving an indication of the first audio content by a microphone of the audio playback device;
• determining a first acoustic response of a room in which the audio playback device is located based on the received indication of first audio content by the microphone;
• applying a mapping to the first acoustic response to determine a second acoustic response, wherein the second acoustic response is indicative of an approximated acoustic response of the room at a spatial location different from a spatial location of the microphone;
• and
• adjusting based on the second acoustic response audio content output by the speaker.

A computer readable storage medium including instructions for execution by a processor, the instructions, when executed, cause the processor to implement a method comprising:

• outputting first audio content by a speaker of an audio playback device;
• receiving an indication of the first audio content by a microphone of the audio playback device;
• determining a first acoustic response of a room in which the audio playback device is located based on the received indication of first audio content by the microphone;
• applying a mapping to the first acoustic response to determine a second acoustic response, wherein the second acoustic response is indicative of an approximated acoustic response of the room at a spatial location different from a spatial location of the microphone;
• and
• adjusting based on the second acoustic response second audio content output by the audio playback device.
