Auracast using STM32WBA65I-DK1

[Sandeep_k]

If I use STM32WBA65I-DK1 board, by enabling or using UAC (USB), can I stream multiple audio files for auracast application, like each song for each channel or subgroup.

[Sandeep_k]

Is it possible or not? If No, is there any alternative boards

Thank you

Hi,

Yes it's possible to stream multiple languages with Auracast through USB. If you need 2 languages, you can use our USBX Auracast github project as a base, then follow the instructions I gave you in your previous ticket to change your Auracast stream to 2 subgroups. Audio received through USB will then be dispatched to first (left channel) and second (right channel) BIS, which will be included in 2 different subgroups to let remote Broadcast Sinks know that they contain 2 different languages. You will need to use a file on the USB host which contains 2 different languages in the left and right audio channels.

If you need more than 2 languages, current STM32WBA libraries doesn't permit it right know but will in the future.

Regards,

Tom.

What if more than 2 audio files to be streamed at a time for more than 2 channels.

Will STM32WBA65I-DK1 board support for more than 2 channels (atleast 10)?

In future is there any possiblity for STM32WBA library or other to permit more channel creation and stream similar audio file with STM32WBA65I-DK1?

Yes, STM32WBA series will support more than 2 channels in future updates.

Although, it will probably never support more than 10 channels. The CPU load required to encode 10 channels is way too high for it, and anyway you wouldn't be able to put 10 different audio channels simultaneously with a decent audio quality (this applies to every chip available on the market).
