Bluetooth SIG Unveils Auracast, A New Way To Multicast

Last Updated on June 10, 2022 by Anu Joy

Auracast is a new technology developed by the Bluetooth Special Interest Group (SIG). This new audio technology includes features such as audio sharing, public listening, and increased accessibility. Bluetooth’s LE Audio includes Auracast, which goes well beyond SIG’s basic point-to-point audio transmission.

Auracast, according to SIG, will allow a single audio transmitter to broadcast to a limitless number of nearby receiving devices. The new technology will open up a host of possibilities, such as enabling venues to broadcast audio straight to attendees’ devices, allowing users to share their audio with others, and allowing Auracast-enabled devices to remotely unmute TVs in public venues. Auracast’s applications are nearly limitless.

Some of the industry’s biggest names, such as Google and Xiaomi, as well as the Hearing Loss Association of America, have already indicated support for the new standard. This means that it will be widely adopted in the long run.

Announcing the Auracast, Mark Powell, CEO of the Bluetooth SIG said, “The launch of Auracast broadcast audio will trigger another massive change in the wireless audio market. The ability to broadcast and share audio using Bluetooth technology will reshape personal audio and enable public venues and spaces to deliver audio experiences that will improve visitor satisfaction and increase accessibility.”
