Calibration of audio playback devices
First Claim
1. An audio playback device comprising:
- a microphone;
a speaker;
a processor comprising instructions, which when executed, cause the processor to;
output by the speaker first audio content;
receive by the microphone an indication of the first audio content;
determine a first acoustic response of a room comprising a microphone location response, in which the audio playback device is located, wherein the determination of the microphone location response is based on the received indication of the first audio content by the microphone, wherein the microphone is on or proximate to the playback device;
applying a mapping to the microphone location response to determine a corresponding second acoustic response comprising a mapped room 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,wherein the mapped room response comprises a historical room response from a set of historical room responses that has a lowest difference as compared to the microphone location response; and
adjust based on the second acoustic response second audio content output by the speaker.

Abstract
An audio playback device comprises a microphone, a speaker, and a processor. The processor is arranged to output by the speaker first audio content and receive by the microphone an indication of the first audio content. A first acoustic response of a room in which the audio playback device is located is determined based on the received indication of first audio content. A mapping is applied to the first acoustic response to determine a second acoustic response. 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. The second audio content output by the speaker is adjusted based on the second response.

1. An audio playback device comprising:
-
a microphone; a speaker; a processor comprising instructions, which when executed, cause the processor to; output by the speaker first audio content; receive by the microphone an indication of the first audio content; determine a first acoustic response of a room comprising a microphone location response, in which the audio playback device is located, wherein the determination of the microphone location response is based on the received indication of the first audio content by the microphone, wherein the microphone is on or proximate to the playback device; applying a mapping to the microphone location response to determine a corresponding second acoustic response comprising a mapped room 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, wherein the mapped room response comprises a historical room response from a set of historical room responses that has a lowest difference as compared to the microphone location response; and adjust based on the second acoustic response second audio content output by the speaker. - View Dependent Claims (2, 3, 4, 5, 6)

7. 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 comprising a microphone location response in which the audio playback device is located, wherein the determination of the microphone location response is based on the received indication of the first audio content by the microphone, wherein the microphone is on or proximate to the playback device; applying a mapping to the microphone location response to determine a corresponding second acoustic response comprising a mapped room 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, wherein the mapped room response comprises a historical room response from a set of historical room responses that has a lowest difference as compared to the microphone location response; and adjusting based on the second acoustic response audio content output by the speaker. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A non-transitory 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 comprising a microphone location response, in which the audio playback device is located, wherein the determination of the microphone location response is based on the received indication of the first audio content by the microphone, wherein the microphone is on or proximate to the playback device; applying a mapping to the microphone location response to determine a corresponding second acoustic response comprising a mapped room 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, wherein the mapped room response comprises a historical room response from a set of historical room responses that has a lowest difference as compared to the microphone location response; and adjusting based on the second acoustic response second audio content output by the audio playback device. - View Dependent Claims (15, 16, 17, 18, 19, 20)
