摘要： A Bluetooth audio streaming passthrough, and a method for transmitting an audio stream over a Bluetooth communication link and disclosed. The method is carried out by a source device. An audio codec configuration and a sampling rate of the audio stream are received, the audio stream coming from a streaming application running on the source device. A Bluetooth audio stream between the source device and a sink device is configured using the received audio codec configuration and sampling rate. The first audio stream is received from the streaming application. The received first audio stream is packetized into the Bluetooth audio stream. The Bluetooth audio stream is transmitted to the sink device over the Bluetooth communication link, including the packetized received audio stream.

摘要： Systems, methods, and machine-readable media facilitate voice distribution. A wireless, bidirectional audio link with each auxiliary device of a plurality of auxiliary devices may be established and simultaneously managed. A first audio signal comprising a first vocal message may be received as input. A third audio signal may be simultaneously received with receipt of the first audio signal. The third audio signal may include a third vocal message that is different from the first vocal message and a second vocal message. The first audio signal may be buffered with a first input buffer of a control device while the third audio signal is buffered with a second input buffer of the control device. Simultaneous bidirectional translation of the first vocal message and the third vocal message may be performed. The second audio signal including a second vocal message may be provided as output.

摘要： In the present disclosure a method is proposed for switching from a first Bluetooth audio source to a second Bluetooth audio source in a user experience friendly manner, e.g. reducing latency. The method is performed by an audio rendering system comprising a primary wireless speaker and a secondary wireless speaker. The audio rendering system receives a first audio stream from the first audio source by using a first audio topology comprising a first set of wireless links. Upon receiving a request to switch to a second audio stream using a second audio topology, a second set of wireless links is established; and, the reception of the second audio stream starts while maintaining the audio rendering system and the first audio source connected by a wireless link of the first set of wireless links. The wireless speaker(s) can be a wireless earbud, a bookshelf speaker, a floor speaker, an outdoor speaker, a subwoofer, a headset speaker.

摘要： The present invention relates to the field of wireless audio streaming. The invention can be used to manage dynamically the configuration of a link between a Bluetooth audio source and a Bluetooth audio sink, or between a master and slave device. The invention relates to method for operating a Bluetooth device, the method comprising: transporting audio information over a Bluetooth communication link established with a second device; determining, upon a change of value of an operational parameter in either the Bluetooth device or the second device, a new operating mode for said Bluetooth communication link; modifying a configuration parameter of said Bluetooth communication link based on the new operating mode; transporting audio information on said Bluetooth communication link according to the modified configuration parameter.

摘要： Audio rendering devices comprising at least one audio rendering unit for playing audio streams, processing circuit and a wireless communication unit for establishing wireless links and related method are disclosed. One audio rendering device is configured to receive a remote audio stream prioritization policy comprising one or more lists of associations between audio stream attributes and priority values, update a local audio stream prioritization policy based on the remote audio stream prioritization policy, identify audio streams available via wireless links, retrieve audio stream attributes of the available audio streams, select an available audio stream to be played among the available audio streams, based on the updated local audio stream prioritization policy and based on the audio stream attributes of the available audio streams, and play the selected audio stream, by the audio rendering unit of the audio rendering device.
