Hello @Tom_Gean 

The STM32WB/WBA are already low power MCUs that support low power consumption. For the Audio Specificity, the STM32WBA support the Audio LE Technologie which is a last Audio Technologie on BLE that include Low power support.

Best Regrads.

Hi, there,
BLE Audio (Auracast), is available on STM32WBA and not STM32WB.
You can find the answer to your question right here:
Bluetooth_LE_Audio_STM32WBA_LC3_Codec#Clock_tree_and_Low_power 

If you would like more information on BLE Audio, you can find it on this page and others that follow:

BR, Joé
