Unraveling Bluetooth Low Energy Audio: Stretching the Limits of Interoperable Wireless Audio with Bluetooth Next Generation Audio Standards (Paperback)

Pre-order for despatch on publication.


Explore how Bluetooth Low Energy (LE) has transformed the audio landscape, from music streaming to voice recognition applications. This book describes the rationale behind moving to LE audio, the potential power savings, and how various specifications need to be linked together to develop a final end product.

LE Audio is a natural development of the Bluetooth audio standard. The standard is spread across more than a dozen different specifications, from application profiles, down to the core transports in both Host part and Controller part. You'll see how this new architecture of the Bluetooth audio stack defines a LE Audio stack from the Core Controller to the Host Protocols, and Profiles.

You'll also learn how to free yourself from wires and charging. LE Audio introduces a new audio compression codec called LC3 (Low Complexity Communication Codec), which covers sampling rates for the full range of voice and media application at high fidelity, low complexity and low bit-rate and is ideal for new applications - such as voice assistance and gaming.

Unraveling Bluetooth Low Energy Audio provides full context to anyone who is curious to learn about the new LE Audio technology.

What You'll Learn

Understand the advantages of LE audio over current standards

Describe the overall Bluetooth LE audio stack and its various blocks

Enable LE audio with the Core Controller specification

See how an end-to-end application works its through the LE audio ecosystem

Examine how LE Audio addresses current and future trends in interoperable wireless audio

He also contributed to Wi-Fi Direct Services (WFDS) standard and represented Broadcom in the Wi-Fi Alliance. In Intel, he contributed to Wi-Fi Serial Bus (WSB) standard and was instrumental in developing MAUSB (Media Agnostic USB) Software technology. He was a key contributor to Bluetooth Low Energy standard and was editor of multiple critical specifications (ASCP, BAP, etc.). He received the prestigious "Outstanding New Contributor of the year" award for this work from the Chairman of Board of Directors of Bluetooth SIG during the Working Group Summit in Kirkland in 2018. For this, he was featured on the Bluetooth SIG website and also on Bluetooth SIG LinkedIn account, and this was written about him - "The procedures which he defined are a corner stone for LE audio". He was also interviewed inside Intel and his interview was featured in the company's "Inside Blue" portal. He also represents Intel in Bluetooth Architecture Review Board (BARB) and has provided feedback to over 20 specifications spanning across various Bluetooth SIG Working Groups (e.g. Mesh, ATA, GA, etc.). He is also a prolific inventor and has 3 patents granted and 4 more filed with the USPTO. He considers this book as an attempt to give back to the technology and a means to show gratitude to everyone involved in development of this standard. Oren Haggai is a system architect in the wireless connectivity solutions group at Intel. Oren is currently focusing on Bluetooth technology. Oren has 20 years of experience working on various wireless products and standards in general and Bluetooth technology.
