Start developing with Auracast

Hi everyone, I'm a beginner with development Bluetooth and Auracast. In my job, we are going to improve some product we have, and we are thinking about Auracast. So I have few questions about it.

1. If I'm not wrong, with the nrf5340 audio DK I can test with Auracast or this is a feature will be in the future with an update as I seen in a post?

2. The chip nrf5340 has been activated to work with Auracast or only the Audio DK?

  • For the nRF5340 the perfomance envelope at best with some optimization seems to be to
    encode a stereo stream and send over LE Audio
    decode a mono stream with the received LE Audio and,
    USB stack receiving the stereo stream from the host and 
    sending the mono stream back to the host
    simultaneously.

  • Hello David,

    Could you elaborate on what you are referring to here?
    The nRF5340 can do more than what you have listed above - the rule of thumb is that the encoding of a 96 kbps stream will require roughly ~30% CPU utilization, while the decoding of the same stream will require roughly ~16% CPU.

    Best regards,
    Karl
