Bluetooth Low Energy Audio Deep Dive: Architecture, Protocols, Codecs, and Live Demo

Bluetooth LE Audio brings powerful new capabilities to wireless audio, with new protocols, modern codecs, and entirely new use cases that go far beyond classic Bluetooth audio.

Here are just a few real-world examples:

Multi-stream audio
Picture yourself at the airport, listening to a podcast through your earbuds. At the same time, you’ve subscribed to your gate’s public announcement stream. When boarding announcements begin, your podcast automatically ducks or pauses—just enough for you to hear the gate agent clearly, then seamlessly resumes.

Public audio broadcasts

• In a museum, simply open your phone, choose your language, and connect to the exhibit’s audio guide—using your own headphones, no rental device needed.
• At the gym, tap to receive audio from any TV screen, even if you’re on the other side of the room.
• In train stations, airports, theaters anyone can join location-based audio streams.

This talk provides an introduction to BLE LE audio: from the new features and protocols to the challenges in integrating it in a real scenario with a demo between a devkit and an headset.
