LE Audio on nrf52840

[Jash]

Hello,

I was looking for solutions to LE Audio and came across nrf5340. Later on diving deep into this I found that nrf52840 SOC also has BLE 5.3. So, my query was can nrf52840 be used to develop LE Audio applications?

I have also noticed the nrf52840 LE Audio Development kit, so I guess using nrf52840 SOC, I should be able to develop LE Audio applications. If so, what SDK support do I need to download?

It seems that things are still not very clear. For 5340 audio DK,

1.who is doing the LC3 coding-decoding process, or who is running the LC3 code, I suppose it is the 5340 itself, right? 

2.the DSP  CS47L63 on board is acting only as ADC and DAC. It just converts the I2S signal(PCM format)  to analog output to headphone? It doesn't do any compression to audio data, nothing to do with LC3. You can use any other ADC/DAC instead, not concerning about the power consumption or cost etc.  Right?

Appreciate any explanation.

Tks,
