Abstract: Examples described herein involve validating motion of a microphone during calibration of a playback device. An example implementation involves a mobile device detecting, via one or more microphones, audio signals emitted from one or more playback devices as part of a calibration process. After the one or more playback devices emit the audio signals, the mobile device determines whether the detected audio signals indicate that sufficient horizontal translation of the mobile device occurred during the calibration process. When the detected audio signals indicate that insufficient horizontal translation occurred, the mobile device displays a prompt to move the mobile device more while the one or more playback devices emit one or more additional audio signals as part of the calibration process. When the detected audio signals indicate that sufficient horizontal translation occurred, the mobile device calibrates the one or more playback devices with a calibration based on the detected audio signals.

Abstract: 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.

Abstract: Systems and methods for calibrating a playback device include (i) outputting first audio content; (ii) capturing audio data representing reflections of the first audio content within a room in which the playback device is located; (iii) based on the captured audio data, determining an acoustic response of the room; (iv) connecting to a database comprising a plurality of sets of stored audio calibration settings, each set associated with a respective stored acoustic room response of a plurality of stored acoustic room responses; (v) querying the database for a stored acoustic room response that corresponds to the determined acoustic response of the room in which the playback device is located; and (vi) applying to the playback device a particular set of stored audio calibration settings associated with the stored acoustic room response that corresponds to the determined acoustic response of the room in which the playback device is located.

Abstract: Systems and methods for authenticating a passive speaker include (i) activating, by a playback device configured to drive the passive speaker, a passive speaker identification circuit of the passive speaker by providing an identification signal to an input terminal of the passive speaker, wherein the passive speaker is a particular type of passive speaker having particular acoustic characteristics; (ii) while the passive speaker identification circuit is active, measuring, by the playback device, an electrical current of the identification signal; (iii) determining, based on the measured electrical current of the identification signal, an impedance modulation of the passive speaker; (iv) determining, by the playback device, the particular type of the passive speaker based on the impedance modulation of the passive speaker; and (v) applying, by the playback device, a calibration to the playback device based on the determined particular type of the passive speaker.

Abstract: Examples involve calibration of a playback device including multiple audio transducers. An example implementation involves forming a particular playback configuration that configures the multiple audio transducers to form two or more channels and receiving a command to initiate calibration of the particular playback configuration. The calibration includes emitting a calibration sound according to a sequence that involves the calibration sound cycling through frequencies of a calibration frequency range. Based on the command, the playback device emits the calibration sound contemporaneously via the two or more channels. Emission of the calibration sound by each channel is staggered such that each emitted calibration sound is delayed relative to a preceding emitted calibration sound. The playback device receives audio processing coefficients that are based on one or more recordings of the emitted calibration sound; and applies the audio processing coefficients when playing back the audio content as part of the particular playback configuration.

Abstract: An example implementation may involve a control device displaying a prompt to initiate a calibration sequence that involves calibration of a playback device for a given environment in which the playback device is located. The example implementation may also involve the control device displaying (i) a prompt to prepare a playback device for calibration within a given environment, (ii) a prompt to prepare the given environment for calibration of the playback device, and/or (iii) a prompt to prepare the control device for calibration of the playback device. The example implementation may also involve a control device displaying a selectable control, that, when selected, initiates calibration of the playback device. The example implementation may further involve a control device initiating calibration of the playback device.
