Various embodiments provide a multi-audio input, stereo audio output, push-to-talk (PTT) switch device. The device may include an audio processing unit configured to perform spatial separation/positioning for one or a plurality of audio sources. The audio processing unit of the device may apply unique head-related transfer functions (HRTFs) to produce left and right audio outputs that correspond to predetermined or dynamically positioned spatial locations for each of the incoming audio streams.

During an electronic call between two individuals, a sound localization point simulates a location in empty space from where an origin of a voice of one individual occurs for the other individual.

A display apparatus includes: a display; an input interface; and a processor in connection with the display and the input interface and configured to: upon detecting access of a first power amplifier device, output a high-level Hotplug signal at a Hotplug port of the display apparatus; monitor whether a common-mode data packet from the first power amplifier device is received within a first preset duration; in response to the common-mode data packet being received within the first preset duration, send a heartbeat packet to the first power amplifier device, and monitor whether a heartbeat response is received within a second preset duration; in response to the heartbeat response being received within the second preset duration, determine that the first power amplifier device supports e-ARC function; and in response to the heartbeat response being not received within the second preset duration, determine that the first power amplifier device supports ARC function.

A device includes one or more processors configured to receive, via wireless transmission from a streaming device, encoded ambisonics audio data representing a sound field. The one or more processors are also configured to perform decoding of the ambisonics audio data to generate decoded ambisonics audio data. The decoding of the ambisonics audio data includes base layer decoding of a base layer of the encoded ambisonics audio data and selectively includes enhancement layer decoding in response to an amount of movement of the device. The one or more processors are further configured to adjust the decoded ambisonics audio data to alter the sound field based on data associated with at least one of a translation or an orientation associated with the movement of the device. The one or more processors are also configured to output the adjusted decoded ambisonics audio data to two or more loudspeakers for playback.

Implementations of the subject technology provide for sound stage reversal for enclosed environments. For example, various occupants within an enclosed environment and listening to the same spatially-oriented audio content may be facing in various different respective directions. Speakers within the enclosed environment may be operated to generate the spatially-oriented audio content for the various occupants, with various respective sound stage orientations corresponding to the various different respective directions in which the occupants face.

Methods and systems for optimizing a routing of audio data to audio transmitting devices using a Bluetooth network are disclosed. One method includes receiving an encoded audio bitstream at a first speaker of the audio rendering system comprising a first and a second audio channels, separating a first set of spectral components of the first audio channel and a second set of spectral components of the second audio channel from the encoded audio bitstream, without decoding the audio bitstream, generating a first encoded bitstream from the first set of spectral components, and forwarding the first encoded bitstream to a second speaker of the audio rendering system over the wireless link.

Methods and systems for improving the robustness of wireless communications. The methods and systems provided transmit data packets over a first isochronous stream and transmit one or more supplemental data packets over the same time intervals. The one or more supplemental data packets are used to re-create and/or enhance at least a portion of one or more data packets of the plurality of data packets that have already been sent. Alternatively, the one or more supplemental data packets are used to create and/or enhance at least a portion of one or more data packets of the plurality of data packets that will be received during the next isochronous intervals. The methods and system described herein allow for increased robustness by allowing for better retransmission with correctly received packets and the methods set forth herein work with any Bluetooth broadcaster sink without modification.

In one aspect, a method for providing a binaural recording to a listener with a head applied in a hearing system, whereas the binaural recording is listened to using a hearing device and whereas the binaural recording consists of a left binaural ear signal intended for a left ear of the listener, and a right binaural ear signal intended for a right ear of the listener, comprises determining a head orientation, determining a source direction of the binaural recording with respect to the head orientation, detecting a change of the head orientation to a new head orientation, adapting the binaural recording considering the source direction of the binaural recording and the new head orientation.

An electronic device modifies a first media content item by superimposing a first set of data over a first accented musical event. The first accented musical event has a first audio profile. The first set of data has a second audio profile configured to be masked by the first audio profile during playback of the first media content item. The electronic device transmits, to a second electronic device, the modified first media content item.

A method provides binaural sound to a person through electronic earphones. The binaural sound localizes to a sound localization point (SLP) in empty space that is away from but proximate to the person. When an event occurs, the binaural sound switches or changes to stereo sound, to mono sound, or to altered binaural sound.
