Introducing Bluetooth LE Audio: A guide for developers, technology strategists, analysts and investors wanting to understand the new Bluetooth LE Audio standard.

The recently published Bluetooth® LE Audio specifications open up a new era of applications for wireless audio. They build on the incredible success of True Wireless earbuds, providing a toolkit allowing designers to extend their imagination into new realms of possibility, offering enhanced audio quality, new user experiences and lower power. That flexibility involves a steep learning curve. The new specifications comprise over twenty separate documents, building on the Bluetooth Core 5.2 specification, which introduced audio capabilities to Bluetooth low energy. This new architecture provides designers with far more features than the previous A2DP and HFP audio profiles, as well as introducing the concepts of broadcast and audio sharing. For designers looking at new audio applications, working out how all of these pieces fit together, and the optimal way to use them, can be daunting. This book guides you through the specifications, illustrating how they work together and describing how to use them to develop innovative new applications. As well as providing guidance to the specifications, this book also explains the growth in the wireless audio market, including the phenomenal success of True Wireless earbuds, which have become the fastest growing consumer product the world has ever seen. It explains the new use cases which will change the wireless audio market, including audio sharing, broadcast audio and the use of audio in augmented reality.
