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.
