nRF Audio applications

The nRF Audio applications demonstrate audio playback over isochronous channels (ISO) using LC3 codec compression and decompression, as per Bluetooth® LE Audio specifications.

Note

nRF Audio applications and their DFU/FOTA functionality are marked as experimental.

The following table summarizes the differences between the available nRF Audio applications.

Differences between nRF Audio applications

Application name (LE Audio role)	Application mode	Minimum amount of audio devices recommended for testing	FEM support
Broadcast sink	BIS (headset)	2
Broadcast source	BIS (gateway)	2	✔
Unicast client	CIS (gateway)	2 (three for CIS with TWS)	✔
Unicast server	CIS (headset)	2 (three for CIS with TWS)	✔
