Bluetooth LE Audio

The future of wireless audio

Bluetooth is by far the most recognized wireless standard for audio streaming, with an estimated 1.1 billion devices shipped in 2020. LE Audio and Auracast™ are expected to boost this number, with earbuds as the main contributor.

LE Audio is the next generation of Bluetooth Audio, making audio streaming over Bluetooth Low Energy possible. It enables new use cases and significantly reduces power consumption compared to Classic (BR/EDR) Audio.

Bluetooth LE Audio is developed to enhance performance in power consumption, latency, and bandwidth. LE Audio and Classic Audio standards will continue to coexist and have features that will be supported by both. LE Audio will have a wider set of features, lower power consumption, and better perceived audio quality.

Enabling new audio applications
We ship more than 1 million Bluetooth LE System-On-Chips (SoCs) every day and are the Bluetooth LE market leader. We offer complete solutions for building LE Audio products. Our nRF5340 is a powerful dual-core SoC designed to meet all requirements of LE Audio. If you are planning to build a LE Audio product or have questions, do not hesitate to contact us.

Get the right hardware

We offer the ideal development hardware to get started with your LE Audio project. 

The nRF5340 Audio DK is configurable and can function as a USB dongle to send or receive audio data from a PC. It can also function as a Headset or a True Wireless Stereo (TWS) Earbud. For most use-cases, we recommend using two or more DKs. Our kits come with a SEGGER on-board J-Link debugger.

To measure current consumption we recommend having a look at the Power Profiler Kit ll. Use it with any of our development kits, prototyping platforms, or your own designs. PPK2 works all the way from sub-µA to 1 A and can log up to 500 days as is.
