Indoor/outdoor playback device calibration
First Claim
1. A playback device comprising:
- one or more audio transducers;
one or more amplifiers configured to drive the one or more audio transducers;
one or more microphones;
a network interface;
one or more processors; and
a housing carrying the one or more audio transducers, the one or more amplifiers, the one or more microphones, the network interface, the one or more processors, and data storage having stored therein instructions executable by the one or more processors to cause the playback device to perform functions comprising;
applying a first equalization profile that at least partially offsets acoustic characteristics of a first zone in a media playback system, wherein the first zone corresponds to an indoor environment;
playing back audio content using the first equalization profile via the one or more audio transducers and the one or more amplifiers;
recording, via the one or more microphones, at least a portion of the played back audio content;
based on the recorded audio content, detecting that the playback device has been moved to an outdoor environment; and
responsive to detecting that the playback device has been moved to the outdoor environment, applying a second equalization profile that calibrates the playback device to the outdoor environment.

Abstract
Techniques described herein may involve calibration of playback devices in indoor and outdoor environments. An example implementation may involve a playback device applying a first equalization profile that at least partially offsets acoustic characteristics of a first zone in a media playback system, the first zone corresponding to an indoor environment. The playback device may play back audio content using the first equalization profile and record, via one or more microphones, at least a portion of the played back audio content. Based on the recorded audio content, the playback device may detect that the playback device has been moved to an outdoor environment. Responsive to detecting that the playback device has been moved to the outdoor environment, the playback device applies a second equalization profile that calibrates the playback device to the outdoor environment.

9. A method to be performed by a playback device, the method comprising:
-
applying a first equalization profile that at least partially offsets acoustic characteristics of a first zone in a media playback system, wherein the first zone corresponds to an indoor environment; playing back audio content using the first equalization profile via one or more audio amplifiers configured to drive one or more audio transducers, wherein the one or more amplifiers and the one or more audio transducers are carried in a housing of the playback device; recording, via one or more microphones, at least a portion of the played back audio content, wherein the one or more microphones are carried in the housing of the playback device; based on the recorded audio content, detecting that the playback device has been moved to an outdoor environment; and responsive to detecting that the playback device has been moved to the outdoor environment, applying a second equalization profile that calibrates the playback device to the outdoor environment. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A tangible, non-transitory, computer-readable medium having stored therein instructions executable by one or more processors to cause a playback device to perform functions comprising
applying a first equalization profile that at least partially offsets acoustic characteristics of a first zone in a media playback system, wherein the first zone corresponds to an indoor environment; -
playing back audio content using the first equalization profile via one or more audio amplifiers configured to drive one or more audio transducers, wherein the one or more amplifiers and the one or more audio transducers are carried in a housing of the playback device; recording, via one or more microphones, at least a portion of the played back audio content, wherein the one or more microphones are carried in the housing of the playback device; based on the recorded audio content, detecting that the playback device has been moved to an outdoor environment; and responsive to detecting that the playback device has been moved to the outdoor environment, applying a second equalization profile that calibrates the playback device to the outdoor environment. - View Dependent Claims (17, 18, 19, 20)
