  • Patent number: 10419864
    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: A data encoding may be determined by examining the data itself. By examining the data, such as by identifying characteristics of the data, the data encoding may be identified and the substantive information extracted from the data by decoding the data according to the identified data encoding. The data encoding may be identified without extra control or header information separate from the encoded data itself. The identification of data encoding may be determined by a plurality of detectors examining different characteristics of the data and determining an encoding of the data based on each of those individual characteristics. The output of the detectors may be collected and used to decide the encoding of the data. One example application involves determining if audio data is DSD- or PCM-encoded audio data by examining only the data itself.

  • Patent number: 10021503
    Abstract: Example techniques involve determining a direction of an NMD. An example implementation includes causing two audio drivers to output audio content, where the audio drivers are positioned at a known distance apart in a given azimuthal plane and recording the audio content output by the two audio drivers. The implementation also includes causing a computing device to identify a direction of the NMD relative to a center point of the two audio drivers in the given azimuthal plane. Identifying the direction of the NMD may involve determining a range of possible azimuthal angles between the NMD and the center point, the range of possible angles dependent upon the known distance between the two audio drivers and a phase offset between the two audio drivers indicated by the recorded audio content output. The implementation further includes causing a playback device to adjust calibration based on the identified direction of the NMD.

  • Patent number: 9992592
    Abstract: A method of assessing noise involves evacuating air from a vacuum chamber to a pressure less than about 1 Torr and stimulating a device positioned in the chamber by shaking it or by operating a component of the device. Measuring vibrations in a low pressure environment decreases or eliminates propagation of sound waves, thereby enabling isolation and identification of vibrations caused by mechanical noise. These measurements may be useful for more precise acoustic characterization of audio devices containing multiple components.

  • Patent number: 9992597
    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.
