Xiaomi Auracast™ Redefines Full-Scene Audio at the 2026 Bluetooth Asia Conference

The 2026 Bluetooth Asia Conference and Exhibition concluded in Shenzhen, gathering over 60 exhibitors and 50+ keynote sessions under the theme "Defining Standards, Changing the World" and emphasizing China's role in global Bluetooth standards.

SIG Audio Ecosystem Booth: Three Real‑World Scenarios

Xiaomi demonstrated Auracast™ broadcast audio, Channel Sounding ranging and HDT high‑throughput in three flagship demos: a silent‑TV for gyms, an audio‑sharing system for high‑speed‑rail stations, and real‑time multilingual translation in the main hall.

Gym Silent‑TV

Using Auracast™ broadcasting, the TV continues video playback while audio is streamed directly to users' earphones, achieving "watch without disturbing, listen freely"; users control volume independently, solving the traditional audio‑video conflict in public fitness spaces.

High‑Speed‑Rail Audio Sharing

One source broadcasts to all nearby Auracast™‑compatible devices, delivering clear, low‑latency sound even in noisy environments; the broadcast is encrypted with password protection, mirroring Wi‑Fi security.

Multilingual Conference Translation

Every presentation was broadcast via Auracast™; attendees switched between Chinese, English and other language channels with near‑zero delay, providing a seamless "understand every word" experience.

Industry Talk: Future of LE Audio and Auracast™

Bluetooth SIG China Interest Group (CIG) audio promotion chair Zhang Haishen presented "Unlimited Listening in a New Era" and highlighted Auracast™'s ability to break point‑to‑point limits, enabling unlimited receivers for a free listening experience.

Xiaomi Ecosystem and Openvela Open‑Source Stack

Leveraging the "person‑car‑home" strategy, Xiaomi integrates Auracast™ across phones, tablets, TVs and wearables, supported by the openvela open‑source Bluetooth solution that offers rich features, low power consumption and strong compatibility. Openvela’s AIoT Channel Sounding implementation improves ranging accuracy from meter‑level to sub‑meter, while BES demonstrated HDT data rates up to ~6 Mbps, far exceeding classic Bluetooth speeds.

IoT and Smart‑Home Demonstrations

Mesh 2.0 lighting control, motion‑aware lighting and multi‑switch coordination were showcased, powered by over 60 MHCB13G modules forming a stable Bluetooth Mesh network; the Xiaomi IoT platform, with more than 9 billion connected devices, leverages low‑power, low‑latency Bluetooth for seamless smart‑home experiences.

Detailed Auracast™ Configuration Workflow

On a TV, users enable "Audio Broadcast" via Settings → External Devices → More Settings, turning the TV into an Auracast™ transmitter. Earphones, lacking autonomous scanning, use a paired phone (the Auracast™ Assistant) to discover broadcasts under Settings → Bluetooth → Advanced → Audio Broadcast. Users can also scan a dynamic QR code generated by the transmitter for one‑tap pairing; after connection, the assistant can disconnect while the receiver continues playback.

Future Outlook

With Xiaomi’s continued "person‑car‑home" integration, Auracast™ is poised to expand into home theaters, smart offices, public venues and large arenas, turning Bluetooth from a point‑to‑point link into a multi‑device broadcast infrastructure that delivers low‑latency, high‑concurrency and secure audio sharing across the IoT landscape.
