Abstract: Examples described herein involve providing playback device calibration user interfaces to guide a calibration process for one or more playback devices in a playback environment. In one example, providing the user interfaces involves receiving audio data from the microphone for a predetermined duration of time, and while receiving the audio data, dynamically providing for display on a graphical interface, (i) representations of frequency responses determined based on audio data that have been received from the microphone, and (ii) representations of times within the predetermined duration of time that correspond to the displayed representations of frequency responses.

Abstract: An example implementation may involve a control device receiving, from a first playback device of a media playback system, a calibration state variable indicating that the first playback device is uncalibrated. The control device may cause a graphical interface to display an indication that the first playback device is uncalibrated. The control device may also cause the graphical interface to display a selectable control that, when selected, initiates calibration of the first playback device. Based on detecting selection of the selectable control, the control device may initiate calibration of the first playback device.

Abstract: Examples described herein involve identifying one or more error conditions during calibration of one or more playback devices in a playback environment. A microphone of a network device may detect and sample an audio signal while the one or more playback devices in the playback environment plays a calibration tone. A processor of the network device may then receive, from the microphone, a stream of audio data. The audio data may include an audio signal component and a background noise component. As a subset of the audio data is received, the processor may identify based on at least the subset of audio data, the one or more error conditions. The processor may then cause a graphical display to display a graphical representation associated with the identified error condition.

Abstract: An example implementation may involve receiving, via a network interface, an indication that the first playback device is calibrated. The implementation may also involve updating a calibration state variable to indicate that the first playback device is calibrated based on receiving the indication that the first playback device is calibrated. The implementation may further involve sending, via the network interface, an indication of the updated calibration state variable to a second device.
