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 method is performed by a media playback system comprising a plurality of audio drivers configured to output audio content according to a first radiation pattern that produces an inherent directional effect. Based on data indicating characteristics of a listening area in which the media playback system operates, the system determines first and second transfer functions corresponding to the first and second audio drivers, respectively. One or both of the transfer functions configure the first and second audio drivers to output audio content according to a second radiation pattern that produces a modified directional effect relative to the first radiation pattern. The system applies the transfer function to audio content thereby causing the first and second audio drivers to play back audio content according to the second radiation pattern.

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: 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: An example method is performed by a media playback system comprising a plurality of audio drivers having a first radiation pattern. The method includes receiving data representing audio content, where each datum of the data indicates (i) a frequency and (ii) an amplitude corresponding to the frequency. The method further includes, for each audio driver of the plurality of audio drivers, determining a transfer function; processing each datum of the data based on (i) the frequency indicated by the given datum and (ii) the determined transfer function; and providing, to the given audio driver, a respective signal representing the data processed for the given audio driver, thereby causing the plurality of audio drivers to play back the audio content according to a second radiation pattern that is different from the first radiation pattern. An example media playback system and an example non-transitory computer-readable medium related to the example method is also disclosed herein.

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: Examples described herein involve validating motion of a microphone during calibration of a playback device. An example implementation involves a control device receiving an indication that the control device will begin detecting audio signals emitted from playback devices as part of a calibration process. While the control device is detecting audio signals emitted from the playback devices, the control device receives a stream of motion data indicating movement of the control device. The control device processes a first subset of the stream of motion data to determine that the first subset of the stream of motion data indicates sufficient horizontal translation of the control device occurred. Based on determining that the first subset of the stream of motion data indicates sufficient horizontal translation of the control device, the control device processes a second subset of the stream of motion data.

Abstract: 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.
