    摘要: A first audio computing system to establish a connection with an audio source within a first network, establish a connection with a second audio computing system within a second network, receive, from the audio source via the connection within the first network, a first audio packet, the first audio packet including audio data, receive, from the second audio computing system, a receipt time, the receipt time indicating when the second audio computing system received, from the audio source within the first network, a second audio packet, the second audio packet including the audio data included in the first audio packet, calculate a rendering time based on a time of receiving the first audio packet and the receipt time, send the rendering time to the second audio computing system via the second network, and output audio based on the audio data.

    摘要: Disclosed wireless systems, devices, and methods can leverage existing hardware for BLE communications to provide a low-latency streaming (LLS) link suitable for supporting CROS and BiCROS features in hearing aids. An illustrative embodiment of a low-latency audio streaming method includes: (a) sending intermittent packets of digital audio data as a wireless signal; and (b) for each intermittent packet: (A) listening for a responsive packet; and (B) sending the digital audio data in a retransmitted packet only if no responsive packet is detected. Any retransmitted packet that is sent follows the corresponding intermittent packet with a delay no greater than a length of two interframe spacing (IFS) intervals separated by a responsive packet. An illustrative embodiment of a low-latency audio streaming device includes a transmit chain and a receive chain. The transmit chain periodically transmits intermittent packets of digital audio data as a wireless signal. The receive chain operates to detect a responsive packet to each intermittent packet. The transmit chain retransmits a packet of digital audio data each time the receive chain fails to detect a responsive packet, ensuring a delay no greater than a length of two IFS intervals separated by a responsive packet.
