What Is Auracast Broadcast Audio?
2026-02-05 14:19

Why can wireless headphones usually connect to only one device at a time?
Why is sharing the same song, movie, or live audio with friends still so inconvenient?
Auracast™ Broadcast Audio is the biggest breakthrough in the wireless audio world in over 20 years. Built on BT LE Audio, Auracast introduces a completely new way of transmitting sound—one that feels less like a phone call and more like audio Wi-Fi or radio broadcasting.
As a manufacturer deeply involved in wireless audio development, BWOO believes Auracast will change how people experience sound, just as Wi-Fi reshaped how we access the internet.
How Auracast Works: Think of It as "Audio Wi-Fi"
To understand Auracast, it helps to compare it with how traditional wireless audio works.
From "Handshake" to "Broadcast"
Traditional wireless audio
Works like a phone call
Requires one-to-one pairing and manual authorization
Limited to a single receiver in most cases
Auracast Broadcast Audio
Works like a radio station
The source simply broadcasts audio
Listeners discover and join the stream instantly
No traditional pairing required
The Three Core Roles in Auracast
Broadcaster
A phone, TV, laptop, or public audio system that transmits audio
Assistant
A smartphone or smartwatch used to scan, select, and manage available broadcasts
Receiver
Auracast-enabled headphones, speakers, or hearing devices—such as future BWOO audio products
This architecture allows audio to be shared freely, efficiently, and at scale.
Three Key Advantages of Auracast
1. Unlimited Listeners, One Source
A single broadcaster—such as a TV in a gym or airport—can stream audio to hundreds or even thousands of receivers simultaneously, without interference or bandwidth collapse.
This is impossible with traditional one-to-one wireless connections.
2. Lower Latency, Clearer Sound
Auracast uses the LC3 audio codec, designed specifically for LE Audio.
Compared with classic wireless audio:
Latency is reduced by more than 50%
Audio clarity improves at lower bitrates
Power consumption is significantly lower
For video viewing and public displays, this means better sync and cleaner sound.
3. Public Spaces Become Personal
Auracast enables private listening in public environments:
Gyms
Airports
Waiting rooms
Sports bars
Instead of turning up loudspeakers, users simply connect their own headphones and listen comfortably—on their own terms.
