  • Patent number: 10171929
    Abstract: In some implementations, a positional audio assignment system is used to improve a user's immersion during content playback within a virtual reality setting. Data representing a video viewable to a user identifying spatial positions assigned to one or more objects within the video is initially obtained. Audio data encoding one or more audio streams corresponding to each of the one or more objects is also obtained. User input data associated with playback of the video is then received. A gaze point of the user based on the received user input data is then determined. The gaze point of the user is then evaluated with respect to the spatial positions assigned to the one or more objects. The audio output provided to the user is then selectively adjusted based on evaluating the gaze point with respect to the spatial positions assigned to the one or more objects.

  • Patent number: 10149087
    Abstract: A loudspeaker cabinet has a number of pairs of microphones, each pair includes the same internal microphone and a different external microphone. For each pair of microphones, a process (i) receives a first audio signal of sound captured by the internal microphone and a second audio signal of sound captured by the different external microphone, (ii) estimates, using first and second audio signals, a radiation impedance, and (iii) computes a detection value based on the radiation impedance in a frequency band. A difference between (i) a currently computed detection value associated with a given pair of microphones and (ii) a previously computed detection value associated with said given pair, is computed. The sound produced by the cabinet is adjusted, in response to the computed difference meeting a threshold. Other embodiments are also described and claimed.

  • Patent number: 10104471
    Abstract: Example aspects of the present disclosure are directed to providing tactile bass response by a user device. For instance, a first audio signal can be caused to be output by a first user device and a second user device. A playback delay can be determined between the output of the first audio signal by the first user device and the output of the first audio signal by the second user device. At a first time, the second user device can be caused to output a second audio signal. The first user device can be caused to execute a tactile bass response representation associated with the second audio signal, such that the tactile bass response is executed at a second time, the second time being determined based at least in part on the temporal delay.

  • Patent number: 10070236
    Abstract: The present invention extends to methods, systems, and computer program products for managing audio output through an intermediary. In some embodiments, an audio controller emulates a direct connection between an audio source device and an audio output device. In other embodiments, audio content local to an audio controller is combined with other audio content passing through the audio controller on its way from an audio source device to an audio output device. In additional embodiments, an audio output device is locked to an audio controller. The lock survives power cycling and soft resets of the audio output device. A special hard reset can be used to release the audio output device.

  • Patent number: 9817100
    Abstract: An array of microphones placed on a mobile robot provides multiple channels of audio signals. A received set of audio signals is called an audio segment, which is divided into multiple frames. A phase analysis is performed on a frame of the signals from each pair of microphones. If both microphones are in an active state during the frame, a candidate angle is generated for each such pair of microphones. The result is a list of candidate angles for the frame. This list is processed to select a final candidate angle for the frame. The list of candidate angles is tracked over time to assist in the process of selecting the final candidate angle for an audio segment.

  • Patent number: 9774967
    Abstract: Acoustic transducer aging compensation is effective for an acoustic transducer that is driven with an adjustable drive power to output a signal. A microphone can measure the amplitude of the transmitted signal corresponding to a transmitted sound pressure level (SPL). A controller can periodically compare the transmitted SPL to the drive power or a previous SPL, and determine if the received SPL has declined with respect to the input drive power over time, whereupon the controller can direct an increase in drive power to the SPL-declined acoustic transducer to compensate for the decline in received SPL. If drive power is at a maximum, the controller can further instruct a mobile device receiver to lower its receiver detection threshold for the signal from the SPL-declined acoustic transducer to further compensate for the decline in SPL from that acoustic transducer.
