  • Patent number: 10805753
    Abstract: Embodiments described herein reduce latency and improve packet delivery when transmitting audio packets from a source device to one or more sink devices. For example, one or more operating modes that introduce latency when transmitting packets may be disabled at the source device and/or sink device(s). Additionally, certain operational behavior of the source device and/or sink device(s) may be changed based on the quality of the channel used to transmit audio packets to further improve the latency. Such operational behavior includes changing the jitter buffer size of the sink device(s), the number of retry attempts performed by the source device when re-transmitting packets that have been lost, and changing the channel used to transmit the audio packets. Embodiments described herein further enable the synchronization of playback between the sink devices to ensure that sink devices playback audio packets in a synchronized fashion.

  • Patent number: 10750282
    Abstract: The amount of far-field noise transmitted by a primary communication device in an open-plan office environment is reduced by defining an acoustic perimeter of reference microphones around the primary device. Reference microphones generate a reference audio input including far-field noise in the proximity of the primary device. The primary device generates a main audio input including the voice of the primary speaker as well as background noise. Reference audio input is compared to main audio input to identify the background noise portion of the main audio signal. A noise reduction algorithm suppresses the identified background noise in the main audio signal. The one or more reference microphones defining the acoustic perimeter may be included in separate microphone devices placed in proximity to the main desktop phone, microphones within other nearby desktop telephone devices, or a combination of both types of devices.

  • Patent number: 10750302
    Abstract: A user interface for a head-mounted wearable device provides many functions to a user. Information about whether the device is being worn (donned) or not worn (doffed) may be acquired in several ways. Force sensing resistors in the device may provide output indicative of the pressure associated with wearing the device. Output from a bone conduction (BC) microphone may be analyzed to determine if the device is in use. Piezoelectric BC speakers typically used to present audio output to a wearer provide changes in voltage corresponding to a change in pressure associated with wearing the device. A BC speaker may emit a signal that is detected by the BC microphone, with changes in the signal strength being used to determine if the device is donned or doffed.

  • Patent number: 10728667
    Abstract: The contained Pass And Limit Modulator removes approximately 50% common or in phase information from two inputs as compared to summing both inputs. This output can be used in a whole building music system or in a mono amplitude modulated radio transmission down-mixed from stereo audio content. The center channel (dialogue) is lowered 50% as not to overpower the music. With the Active Channel Crossover System the center channel is further processed and mixed to obtain multiple output channels. Interactive left and right channel frequency decomposition of a stereo signal is performed for optimum reproduction of a down converted front center channel. This way channel removal speed is respective to the frequencies removed. Further processing reduces the interactive left and right channel frequency decomposed content within the center channel output. As a result, the down-mixed front center channel is reproduced more closely as intended to be heard in its original stereo form.
