Abstract

Examples described herein involve calibrating a playback device. An example implementation involves causing a network device to display a guide to calibrate at least one playback device, the guide comprising an indication that the network device is to be moved during a given time. The example implementation also involves detecting, via the network device during the given time, an audio signal played by the at least one playback device. The example implementation further involves causing, via the network device, identification of an audio processing algorithm based on data indicating the detected audio signal.

Claims

1. A method comprising:

causing a network device to display a guide to calibrate at least one playback device, the guide comprising an indication that the network device is to be moved during a given time;

detecting, via the network device during the given time, an audio signal played by the at least one playback device; and

causing, via the network device, identification of an audio processing algorithm based on data indicating the detected audio signal.

2. The method of claim 1, wherein the given time comprises a predetermined duration of time.

3. The method of claim 2, wherein causing the network device to display the guide to calibrate the at least one playback device comprises causing the network device to display an indication of an amount of time remaining in the predetermined duration of time.

4. The method of claim 1, wherein the indication that the network device is to be moved during the given time comprises an indication that the network device is to be moved while the at least one playback device is playing the audio signal.

5. The method of claim 1, wherein the indication that the network device is to be moved during the given time comprises an indication that the network device is to be moved through at least one given location while the at least one playback device is playing the audio signal.

6. The method of claim 1, the method further comprising:

detecting, via the network device, movement of the network device.

7. The method of claim 6, the method further comprising:

sending, via the network device to one or more of the at least one playback device, a message indicating that the network device is moving.

8. The method of claim 1, wherein causing identification of the audio processing algorithm comprises:

sending, via the network device to a computing device, data indicating the detected audio signal; and

receiving, via the network device from the computing device, data indicating the identified audio processing algorithm.

9. The method of claim 1, further comprising:

causing, via the network device, the at least one playback device to play the audio signal.

10. The method of claim 1, wherein the at least one playback device comprises at least two playback devices.

11. The method of claim 1, the method further comprising:

sending, via the network device to the at least one playback device, data indicating the identified audio processing algorithm.

12. The method of claim 1, the method further comprising:

storing, via the network device, data indicating the identified audio processing algorithm.

13. A non-transitory computer-readable medium having stored thereon program instructions executable by a processor to perform functions comprising:

causing a network device to display a guide to calibrate at least one playback device, the guide comprising an indication that the network device is to be moved during a given time;

detecting, via the network device during the given time, an audio signal played by the at least one playback device; and

causing, via the network device, identification of an audio processing algorithm based on data indicating the detected audio signal.

14. The non-transitory computer-readable medium of claim 13, wherein the given time comprises a predetermined duration of time.

15. The non-transitory computer-readable medium of claim 14, wherein causing the network device to display the guide to calibrate the at least one playback device comprises causing the network device to display an indication of an amount of time remaining in the predetermined duration of time.

16. The non-transitory computer-readable medium of claim 13, wherein the indication that the network device is to be moved during the given time comprises an indication that the network device is to be moved while the at least one playback device is playing the audio signal.

17. The non-transitory computer-readable medium of claim 13, wherein the indication that the network device is to be moved during the given time comprises an indication that the network device is to be moved through at least one given location while the at least one playback device is playing the audio signal.

18. The non-transitory computer-readable medium of claim 13, the functions further comprising:

detecting, via the network device, movement of the network device.

19. The non-transitory computer-readable medium of claim 18, the functions further comprising:

sending, via the network device to one or more of the at least one playback device, a message indicating that the network device is moving.

20. A network device comprising:

a processor; and

memory including instructions stored therein executable by the processor to perform functions comprising;

causing the network device to display a guide to calibrate at least one playback device, the guide comprising an indication that the network device is to be moved during a given time;

detecting, during the given time, an audio signal played by the at least one playback device; and

causing identification of an audio processing algorithm based on data indicating the detected audio signal.
