摘要： A control device controls sound of a plurality of speakers. The control device includes: a generation unit acquiring image data and generates display image data from the image data by using conversion processing using shape information indicating a shape of a display surface; a display controller displaying a display image on the display surface by using the display image data; a receiver causing a cursor to be superimposed and displayed on the display image and receives position designation related to the plurality of speakers on the display image from a user who has visually recognized the cursor; and an identification unit calculating a position of the cursor from the position designation by referring to a correspondence relationship between the image data before the conversion processing and the display image data after the conversion processing, and identifying the position of the cursor as a position related to the plurality of speakers.

摘要： One embodiment provides a computer-implemented method that includes acquiring, via at least one microphone, sound pressure data from a loudspeaker in a room. The sound pressure data is input into an artificial intelligence (AI) model. The AI model automatically estimates, without user interaction, at least one of energy average (EA) in a listening area or total sound power (TSP) produced by the loudspeaker. The AI model is trained prior to automatically estimating the at least one of the EA in the listening area or the TSP produced by the loudspeaker.

摘要： Systems and methods discussed herein involve designating a default playback device in a local playback network. One method may involve determining that a networked microphone device is available for assignment to one or more playback zones within a local playback network, displaying a prompt to indicate at least one playback zone to which the network microphone device is to be assigned, receiving an input indicating a particular playback zone in the local playback system to which the network microphone device is to be assigned, and storing data indicating an assignment of the network microphone device to the particular playback zone.

摘要： An example method of operation may include initiating an automated tuning procedure, detecting via one or more microphones a sound measurement associated with an output of one or more speakers at two or more locations, determining a number of speech transmission index (STI) values equal to a number of microphones, and averaging the speech transmission index values to identify a single speech transmission index value.

摘要： An electronic device may exchange packets with a second electronic device. These packets may include transmit times, based on a given clock in a given electronic device when the packets were transmitted. Moreover, when the packets are received by the electronic device, the electronic device may store associated receive times based on a clock in the electronic device. Using minimum time differences between the transmit and receive times, the electronic device may calculate a time offset between the electronic device and the second electronic device, which may then be used to determine future times in a clock domain of the second electronic device. Moreover, the electronic device may provide additional packets to the second electronic device, where a given additional packet includes audio data, and a playback time, corresponding to a given future time, when the audio data is to be played back by the second electronic device.

摘要： Example techniques involve systems with multiple acoustic echo cancellers. An example implementation captures first audio within an acoustic environment and detecting, within the captured first audio content, a wake-word. In response to the wake-word and before playing an acknowledgement tone, the implementation activates (a) a first sound canceller when one or more speakers are playing back audio content or (b) a second sound canceller when the one or more speakers are idle. In response to the wake-word and after activating either (a) the first sound canceller or (b) the second sound canceller, the implementation outputs the acknowledgement tone via the one or more speakers. The implementation captures second audio within the acoustic environment and cancelling the acoustic echo of the acknowledgement tone from the captured second audio using the activated sound canceller.

摘要： An electronic device, while displaying a first interface, receives a request to display an audio settings interface. In response, the electronic device displays the audio settings interface, including a first interface element that enables a first audio mode of an audio output device. Displaying the audio settings interface includes: if the first audio mode is enabled and the electronic device is causing audio that is configured for output using the first audio mode to be output using the first audio mode, displaying the first interface element with a first indication that the first audio mode is being used; and if the first audio mode is enabled and the electronic device is not causing audio to be output using the first audio mode, displaying the first interface element without displaying the first indication that the first audio mode is being used.

摘要： A method is provided, including: defining a plurality of frequency bins; sending, during a training phase, a test signal at different amplitude levels to one or more speakers, and gathering resulting test voltage (V) and current (I) points for the different amplitude levels and for each frequency bin; for each frequency bin, applying a linear regression algorithm to the gathered test voltage and current points for the different amplitudes to obtain a reference electrical impedance of said one or more speakers; sending, during a monitoring phase subsequent to said training phase, an audio signal to said one or more speakers, and gathering resulting new voltage and current points to obtain an operating electrical impedance for said one or more speakers for each frequency bin, determining a deviation between the operating and the reference electrical impedance, and, if the deviation exceeds a defined tolerance, reporting the deviation to a user.

摘要： Example techniques relate to calibration interfaces that facilitate calibration of a playback device. An example implementation may involve outputting a sequence of prompts to guide calibration of a playback device during a calibration sequence comprising (i) a spatial calibration component and (ii) a spectral calibration component. Outputting the sequence of prompts includes outputting one or more first audio prompts representing a guide to perform the spatial calibration component of the calibration sequence. The spatial calibration component involves calibration of the playback device for a particular location within an environment. Outputting the sequence of prompts also includes outputting one or more first second prompts representing a guide to perform the spectral calibration component of the calibration sequence. The spectral calibration component involves calibration of the playback device for the environment.
