  • Patent number: 10129679
    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.

  • Patent number: 10101811
    Abstract: A system providing various improved processing techniques for haptic feedback is described. An acoustic field is defined by one or more control points in a space within which the acoustic field may exist. Each control point is assigned an amplitude value equating to a desired amplitude of the acoustic field at the control point. Transducers are then controlled to create an acoustic field exhibiting the desired amplitude at each of the control points. When human skin interacts with the acoustic field, vibrations of the skin are interpreted by mechanoreceptors being excited and sending signals to the brain via the nervous system. Improved processing techniques allow for more efficient real-world operation.

  • Patent number: 10069471
    Abstract: The present invention provides methods and systems for digital processing of an input audio signal. Specifically, the present invention includes a high pass filter configured to filter the input audio signal to create a high pass signal. A first filter module then filters the high pass signal to create a first filtered signal. A first compressor modulates the first filtered signal to create a modulated signal. A second filter module then filters the modulated signal to create a second filtered signal. The second filtered signal is processed by a first processing module. A band splitter splits the processed signal into low band, mid band, and high band signals. The low band and high band signals are modulated by respective compressors. A second processing module further processes the modulated low band, mid band, and modulated high band signals to create an output signal.

  • Patent number: 10063984
    Abstract: A system and method are described for transforming stereo signals into mid and side components xm and xs to apply processing to only the side-component xs and avoid processing the mid-component. By avoiding alteration to the mid-component XM, the system and method may reduce the effects of ill-conditioning, such as coloration that may be caused by processing a problematic mid-component xM while still performing crosstalk cancellation and/or generating virtual sound sources. Additional processing may be separately applied to the mid and side components xM and xs and/or particular frequency bands of the original stereo signals to further reduce ill-conditioning.

  • Patent number: 10038510
    Abstract: A method of mixing digital audio uses a plurality of mixing buses. Each mixing bus receives at least one input digital audio signal via a respective input. A sample value (801-805) of each input digital audio signal is stored in shared last level cache in the CPU. Then, for each unique input to the mixing buses in turn, the sample values (801-805) of the input digital audio signals are written (806) to a contiguous portion (808) of the shared last level cache. Then, for each input of each of the mixing buses in turn, the sample value for the corresponding input digital audio signal is added to an output value for the bus (809). When complete, the respective output values (810) for each of the mixing buses is then written to shared last level cache.
