Auracast Products
Auracast is a new feature within the Bluetooth standard developed by the Bluetooth SIG. It allows audio to be wirelessly broadcast from one device to multiple receivers simultaneously, without the need for a direct link between each device. This is similar to a radio broadcast, but within a limited space such as an airport, train station, theather, museums or movie theater.
How does Auracast work?
Transmitter: An Auracast transmitter can broadcast audio to an unlimited number of receivers. This can be a smartphone, laptop, television, or even a public address system.
Receiver: The receivers can be earphones, headphones, or even hearing aids, as long as they support Auracast.
Connection: Users can voluntarily (opt-in) connect to an Auracast transmitter.
Why is Auracast interesting?
Public spaces: Auracast is particularly useful in public spaces, such as airports or museums, where users can enjoy announcements, movie soundtracks, or other audio through their own earphones.
Hearing aids: Auracast can make life easier for hearing aid wearers by allowing them to connect directly to an ambient sound source without the need for a telecoil or external accessories.
Audio sharing: Auracast makes it possible to share audio with multiple people at once, for example while watching a movie on the train.
Multiroom: listen to the same music in every room via your own Auracast network.
In practice: Auracast uses Bluetooth LE Audio, an efficient, low-power version of Bluetooth. According to the Bluetooth SIG, this is a new feature within the Bluetooth standard.
