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 example method of operation may include identifying, in a particular room environment, a number of speakers and one or more microphones on a network controlled by a controller and amplifier, providing test signals to play sequentially from each amplifier channel of the amplifier and the speakers, monitoring the test signals from the one or more microphones simultaneously to detect operational speakers and amplifier channels, providing additional test signals to the speakers to determine tuning parameters, detecting the additional test signals at the one or more microphones controlled by the controller, and automatically establishing a background noise level and noise spectrum of the room environment based on the detected additional test signals.

摘要： Systems and methods are provided for providing media content based on playback zone awareness. In one aspect, a computing system receives, via a network interface, zone data from the media playback system, wherein the zone data includes an indication of a particular zone of the media playback system, and wherein the particular zone comprises at least one playback device. The computing system identifies audio content based on (i) the indication of the particular zone and (ii) contextual data associated with the particular zone, and provides, via the network interface, an indication of the identified audio content to the media playback system.

摘要： In one aspect, a first playback device is configured to: (i) play back first audio content in synchrony with a second playback device, (ii) receive, via a network interface, a message indicating second audio content to be output by the first playback device, and (iii) in response to receiving the message indicating the second audio content: (a) cease playing back the first audio content in synchrony with the second playback device; (b) play back the second audio content while the second playback device plays back the first audio content; and (c) after playing back the second audio content, resume playing back the first audio content in synchrony with the second playback device.

摘要： A first playback device and a second playback device of a media playback system play back a first version of audio content in synchrony. While the first and the second playback devices are synchronously playing back the first version of the audio content, a change in at least one characteristic of the media playback system is detected. Based on the change in the at least one characteristic, a second version of the audio content is identified. The second playback device transitions from playing back the first version of the audio content to playing back the second version of the audio content in synchrony with playback of the first version of the audio content by the first playback device. The first and second versions of the audio content are transmitted by at least one remote computing device configured to communicate with the media playback system over at least one data network.

摘要： Example techniques facilitate calibration of a playback device. An example implementation involves a computing device capturing, via a microphone, data representing multiple iterations of a calibration sound as played by a playback device. The computing device identifies multiple sections within the captured data. Two or more sections represent respective iterations of the calibration sound as played by the playback device. Based on the multiple identified sections, the computing device determines a frequency response of the playback device, the frequency response of the playback device representing audio output by the playback device and acoustic characteristics of an environment around the playback device. Based on the frequency response of the playback device and a target frequency response, the computing device determines one or more parameters of an audio processing algorithm and sends, to the playback device, the one or more parameters of the audio processing algorithm.

摘要： Example techniques may involve performing aspects of a spatial calibration. An example implementation may include detecting a trigger condition that initiates calibration of a media playback system including multiple audio drivers that form multiple sound axes, each sound axis corresponding to a respective channel of multi-channel audio content The implementation may also include causing the multiple audio drivers to emit calibration audio that is divided into constituent frames, the multiple sound axes emitting calibration audio during respective slots of each constituent frame. The implementation may further include recording the emitted calibration audio. The implementation may include causing delays for each sound axis of the multiple sound axes to be determined, the determined delay for each sound axis based on the slots of recorded calibration audio corresponding to the sound axes and causing the multiple sound axes to be calibrated.

摘要： Examples described herein involve expanding playback of a media item from a first playback device to a second playback device. In one example, while a first playback device is playing a media item as part of a first zone, the first playback device identifies that a second playback device has moved to a location that is within a given physical proximity of the first playback. The first playback device determines that playback is to be expanded to the second playback device, and transmits a command to cause the second playback device to (i) join the first zone and (ii) begin to play the media item in synchrony with the first playback device.

摘要： An example method of operation may include determining a frequency response to a measured chirp signal detected from one or more speakers, determining an average value of the frequency response based on a high limit value and a low limit value, subtracting a measured response from a target response, and the target response is based on one or more filter frequencies; determining a frequency limited target filter with audible parameters based on the subtraction, and applying an infinite impulse response (IIR) biquad filter based on an area defined by the frequency limited target filter to equalize the frequency response of the one or more speakers.
