 The LE Audio stack is built on the **Bluetooth Core** and the **LC3** codec. The **generic audio framework** includes the Common Audio Profile (CAP), Common Audio Service (CAS), and the profiles and services below. **Use case specific profiles** (HAP, GMAP, TMAP, PBP) sit on top of the generic framework. LE Audio runs over the LE Isochronous Channels (CIS/BIS) supported by :doc:`esp-ble-iso`.

 With these APIs you can create or join Connected ISO Groups (CIG), create or synchronize to Broadcast ISO Groups (BIG), set up ISO data paths, and send or receive isochronous data (e.g., LC3 audio). For higher-level LE Audio profiles and codec APIs, see :doc:`esp-ble-audio`.
