Auracast: Share Audio Instantly with Unlimited Devices
2 Oct
Summary
- Auracast allows unlimited devices to tune into one audio broadcast.
- It uses Bluetooth LE audio with LC3 codec for high quality, low latency.
- QR codes or device menus easily connect users to Auracast streams.
Auracast is set to redefine wireless audio by enabling a single source to broadcast sound to an unlimited number of receivers simultaneously. This Bluetooth-based technology, part of the LE Audio standard introduced in 2022, utilizes the LC3 codec for enhanced audio quality and reduced latency.
Ideal for crowded environments like airports or sports bars, Auracast allows users to tune into desired audio streams by scanning a QR code or selecting from a list, similar to connecting to Wi-Fi. This functionality extends to hearing aids, headphones, and speakers, offering a personalized listening experience.
Compatible devices, including newer Samsung phones and LG TVs, act as broadcasters, while devices like Samsung Galaxy Buds or Oticon hearing aids function as receivers. Although Apple devices currently lack native broadcasting support, users can still access Auracast through companion apps.
The technology's range extends up to 330 feet, and its low latency is crucial for synchronized audio-video experiences in gaming and live events. Auracast streams also include metadata and support for password-protected or multi-language broadcasts.
