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?

Hi Jash,

Codec can be hardware based or software based.. Codec takes data in one form, encodes (ADC) it into another form and decodes (DAC) it at the output end.. The CS47L63 is a high performance low-power audio DSP: https://www.cirrus.com/products/cs47l63/  It takes in the analog audio audio signal, encodes, process and decodes it. The CS47L63’s high-performance DAC and differential output driver are optimized for direct connection to an external headphone load. Please go through the data sheet of CS47L63 to get more understanding..

Nordic semiconductors have two DK based on nrf5340: The nrf5340 DK and nRF5340 Audio DK.. The Audio DK is the one suitable for the audio application and has the CS47L63 chip on it..
