Bluetooth LE Audio and Auracast enable multi-device sound broadcasting

Bluetooth LE Audio and the Auracast feature are introducing new ways to share audio across multiple devices simultaneously. Auracast allows a single source, such as a smartphone, television, or public address system, to act as a broadcast station. Any compatible nearby headphones or speakers can tune into the stream without requiring individual pairing.

Key technical improvements include the LC3 codec, which provides higher audio quality than the standard SBC codec even at 50 percent lower data rates, potentially increasing battery life. The technology also supports Multi-Stream Audio, allowing for synchronized, independent audio streams from a single mobile device.

Samsung Galaxy devices running recent versions of One UI have integrated audio broadcasting capabilities. Users can configure their smartphones to broadcast multimedia or voice content to multiple compatible headphones or speakers, such as Galaxy Buds, by accessing the Connected Devices settings.
