Abstract: A method that includes determining that a wired connection is established between a headset that is worn on a head of a user and the electronic device; establishing a wireless connection between the headset with the electronic device; transmitting, through the wired connection, a first audio signal to the headset for audio playback; receiving, from the headset and via the wireless connection, head tracking data captured by a sensor of the headset, wherein the head tracking data indicates movement of the head of the user; producing a second audio signal by modifying the first audio signal based on the head tracking data; and transmitting, through the wired connection, the second audio signal for audio playback at the headset to account for the movement of the head of the user.

Abstract: A method performed by a first electronic device that is communicatively coupled to a wireless headset, the method includes, while engaged in a call with a second electronic device, communicating with the wireless headset via a bi-directional wireless audio connection; determining that a joint media playback session has been initiated in which the first and second electronic devices are to independently stream media content for separate playback by both of the first and second electronic devices while engaging in the call; and switching to communicate with the wireless headset via a uni-directional wireless audio connection based on a determination of one or more capabilities of the wireless headset, wherein a mix of 1) one or more signals associated with the call and 2) an audio signal of the media content is transmitted to the wireless headset over the uni-directional wireless audio connection.

Abstract: Disclosed are systems and methods to modify the Bluetooth mono HFP protocol to support bi-directional stereo operation for high bandwidth audio including 12-KHz wide-band, 16-KHz super wide-band (SWB), and 24-KHz full band (FB) audio. The techniques leverage the larger packet size and longer duty cycle of the 2-EV5 transport packet and expand the block size of the audio frames generated by the AAC-ELD codec to increase the maximum data throughput from the 64 kbps of the mono HFP protocol to 192 kbps using a stereo HFP protocol. The increased throughput not only supports stereo operations, but allows the transport of redundant or FEC packets for increased robustness against packet loss. In one aspect, the AAC-ELD codec may be configured for dynamic bit rate switching to flexibly perform trade-offs between audio quality and robustness against packet loss. The stereo HFP may configure the maximum throughput based on the desired audio quality.

Abstract: Techniques for routing communication to a common audio output device connected multiple audio signal source devices are disclosed. For each of audio signal source devices, a set of inputs are assessed. The set of inputs can include: an operational state of the audio signal source device, an interaction with the audio signal source device, an audio-producing application being executed by the audio signal source device, or a degree of user interaction with the audio-producing application. At a point in time, an audio routing score is generated for each of the audio signal source devices according to a weighted calculation of the set of inputs based on the assessing. Finally, an audio signal routing decision is made, to route an audio signal from one of the audio signal source devices to the audio output device, based on the audio routing score for each of the audio signal source devices.

Abstract: A source device executing the application can transmit the streaming content to the playback device. The size of the buffer can be changed during the playback of streaming content. To perform the change seamlessly, embodiments can cause the application to provide the streaming content at an increased or decreased rate, depending on how the size of the playback buffer is to be changed. The new buffer size (i.e., smaller or larger amount) can provide improved playback of the streaming content, e.g., based on a latency-reliability tradeoff as determined using various factors (e.g., quality of connection between the devices). The changed rate for providing the streaming content can be achieved by slowing down or speeding up a clock signal that is provided to the application.
