Bluetooth LE Audio - nordicsemi.com

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.
