BLE Audio - many to one, power consumptions of DK?

[Hillman007]

Excited to have ordered my BLE Audio DK which uses NRF5340.

In my use case I am looking for many microphones (audio transmitters) to a single listening device (audio receiver). Ideally, they'd be synchronised reasonably well but again that is something we can deal with in the back-end system. In terms of link robustness, will this work? e.g. 5 senders to one listener? 16bit, 16kHz ideal, but could be reduced if needed. 5 was a random number, even two would be useful. Can one use variable rates on each stream? And then I wasnt sure whether you'd recommend connected or broadcast - I understand connected minimises packet loss due to feedback. 

Finally, any idea of the DK / estimated power consumption for nRF5340 to send a single audio stream?

Thanks in advance,

LE Audio supports broadcast audio, from one audio source (transmitter) to multiple sinks ( receivers )

What you are describing is the opposite ... multiple sources, but only one sink.

Best to try to accomplish that using traditional BLE Central and multiple Peripheral connections.

ie.  not LE Audio

This would be viable ... but best if the microphone transmissions are not persistent. 

i.e. microphone transmission while a person is talking, but not other times.

Thanks for your thoughts. I appreciate that. You dont feel a BLE Audio stream 1:1 is lower power than standard BLE?
