  • Patent number: 11929091
    Abstract: An apparatus and method of blind detection of binauralized audio. If the input content is detected as binaural, a second binauralization may be avoided. In this manner, the user experience avoids audio artifacts introduced by multiple binauralizations.
    Type: Grant

  • Patent number: 11544032
    Abstract: An apparatus and method of interfacing between a source media device and a destination media device. A wireless module passes through an audio signal from the source device to an output device, and transmits a wireless signal to a wireless device that outputs the audio signal. In this manner, the number of devices used for the connections may be reduced.

  • Publication number: 20220366889
    Abstract: Systems and processes for operating an intelligent automated assistant are provided. In one example process, a first and second notification are received and, in accordance with determinations that the respective notifications are to be announced to a user, respective first and second spoken outputs are obtained. An announcement schedule is determined based on the respective types of the notifications and the first and second spoken outputs are provided (e.g., audibly announced) according to the announcement schedule.

  • Patent number: 11425503
    Abstract: Embodiments are described for a method of simultaneously localizing a set of speakers and microphones, having only the times of arrival between each of the speakers and microphones. An autodiscovery process uses an external input to set: a global translation (3 continuous parameters), a global rotation (3 continuous parameters), and discrete symmetries, i.e., an exchange of any axis pairs and/or reversal of any axis. Different time of arrival acquisition techniques may be used, such as ultrasonic sweeps or generic multitrack audio content. The autodiscovery algorithm is based in minimizing a certain cost function, and the process allows for latencies in the recordings, possibly linked to the latencies in the emission.

  • Patent number: 11166101
    Abstract: A system and method of providing a signal to wireless speakers. An audio stick connects to a source device and provides the audio signal to the wireless speakers. The audio stick combines the functionality of two separate devices: an audio receiver device and a transmitter device for the wireless speakers.

  • Patent number: 11115617
    Abstract: An apparatus, method and system for connecting High-Definition Multimedia Interface (HDMI) devices. A loopback device connects between a first source device and a sink device on a first connection; a second source device connects to the sink device on a second connection. The loopback device manages the first connection, passes transition-minimized differential signaling (TMDS) or fixed-rate link (FRL) signals through to the sink device, and outputs audio received from the sink device on the audio return channel (ARC) or enhanced audio return channel (eARC). In this manner, audio that originates from any source device may be output without requiring a direct connection to the loopback device.

  • Patent number: 10779084
    Abstract: Embodiments are described for a method for localizing a set of speakers (106) and microphones (108), having only the times of arrival between each of the speakers and microphones.

  • Patent number: 10587982
    Abstract: Systems and methods are described for an adaptive audio system that renders reflected sound for adaptive audio systems in different ways depending on the orientation of at least one speaker in a set of speakers. A speaker of the system may comprise an integrated speaker having front-firing and upward-firing drivers, a sensor to determine the orientation of the speaker (e.g., horizontal or vertical) and a transceiver and control unit that transmits the orientation to a decoder and receives updated speaker feeds from the renderer based on the orientation.

  • Patent number: 10491851
    Abstract: A system and method of interfacing between a source media device, a destination media device and wireless speakers. A media stick provides the output video signal to the destination media device via a wired signal path, and provides the output audio signal to the wireless speakers via a wireless signal path. In this manner, a user may use a single device—the media stick—as both a connector between the devices and to provide the audio signal to the wireless speakers.
