摘要： Example techniques involve a calibration state variable. An example implementation receives, via a network interface, an indication that the first playback device is calibrated. Based on receiving the indication that the first playback device is calibrated, the example implementation updates a calibration state variable to indicate that the first playback device is calibrated, wherein the calibration state variable is stored in the data storage. The example implementation sends, via the network interface, an indication of the updated calibration state variable to a second device.

摘要： A sound collecting apparatus capable of effectively suppressing sounds other than a target sound is provided. The sound collecting apparatus includes a plurality of microphones. A total number of effective microphone pairs in which a distance between two microphones is smaller than a distance D is larger than a total number of the plurality of microphones. The distance D is represented by D=c/2f, where the frequency of the target sound acquired from each of the plurality of microphones is f and sound velocity is c. When an angle formed by a straight line connecting two microphones configuring an effective microphone pair and a predetermined straight line is θ, the angles θ of all effective microphone pairs acquired from the plurality of microphones are different from each other.

摘要： A method and apparatus to capture sound produced by an audio device including a sound source and a loudspeaker. The apparatus includes a microphone support coupleable to the loudspeaker and a microphone mounted on the support, the microphone being locatable within a volume surrounded by a diaphragm of the loudspeaker and being arranged to detect pressure waves caused by movement of a vibrating element of the loudspeaker. Aspects and embodiments provide an element to capture sounds from a loudspeaker in a manner which is compact and which ameliorates disadvantages associated with alternative arrangements since a greater core sound to ambient sound ratio may be captured.
