Example techniques involve calibration of one or more playback devices. An example implementation involves a playback device playing back audio content using a first calibration via the one or more audio transducers and the one or more amplifiers. The first calibration is based on a response of a listening environment to audio content playback by the playback device. The playback device records, via one or more microphones, at least a portion of the played back audio content. Based on the recorded audio content, the playback device detects a change in the response of the listening environment to audio content playback by the playback device. Responsive to detecting the change in the response, the playback device causes output of a prompt to initiate a calibration procedure for the playback device. The calibration procedure involves a mobile device recording playback by the playback device.

Calibration of playback device(s)

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.

Calibration of playback devices

Systems and methods are provided for device playback calibration. An example implementation involves a network device displaying a guide to calibrate at least one playback device. The example implementation also involves detecting, at a first time, a first audio content rendered by the at least one playback device and detecting, at a second time, a second audio content rendered by the at least one playback device. The example implementation further involves causing determination of an equalization adjustment based on an analysis of the first audio content and the second audio content.

Playback calibration

Systems and methods are provided for device playback calibration. An example implementation involves a computing device receiving, via a microphone, detected audio content rendered by at least one playback device. The implementation also involves the computing device modulating the detected audio content with a modulation signal such that the modulation signal has a modulation frequency determined based on an input frequency range of a processing unit. The implementation also involves providing the modulated audio content to the processing unit; and determining, via the processing unit, an equalization setting for the at least one playback device.

Playback device calibration

Systems and methods are provided for device playback calibration. An example implementation involves a network device detecting, at a first time, a first audio content rendered by at least one first playback device. The example implementation also involves the network device detecting, at a second time, a second audio content rendered by at least one second playback device. The example implementation further involves causing, via the network device, determination of an equalization adjustment for one or more of the at least one first playback device and the at least one second playback device based on an analysis of the detected first audio content and the detected second audio content.

Calibration of multiple playback devices

Systems and methods are provided for device playback calibration. In one example, a calibration device with a microphone and signal processor may detect audio content rendered by a playback device. The calibration device may transmit the detected audio content to a processing unit configured to determine an equalization setting for optimal playback of the playback device based on the received detected audio content and a relative distance and direction between the playback device and the calibration device. The calibration device may further be configured to modulate the detected audio content before transmitting the detected audio content to the processing unit to accommodate for a limited frequency range of the processing unit. In this case, the processing unit may demodulate the received signal prior to determining the equalization setting. The processing unit may then transmit the determined equalization setting to the playback device according to a wireless communication protocol.
