Calibration of playback devices

Abstract:

Example techniques involve calibration of multiple playback devices. An example implementation receives, via a user interface of the network device, an input to initiate calibration of a group of playback devices comprising a first playback device and a second playback device configured to playback audio content in synchrony. After initiating the calibration of the group of playback devices, the implementation detects audio content rendered synchronously by the first playback device and the second playback device. Based on the detected audio content, the implementation determines a first equalization adjustment for the first playback device and a second equalization for the second playback device and causes the first playback device to apply the first equalization adjustment and the second playback device to apply the second equalization adjustment when the first playback device and the second playback device play audio content synchronously as part of the group of playback devices.
