Auracast™ Broadcast Audio
LE Audio adds Auracast™ broadcast audio to Bluetooth® technology. This new feature enables an audio source to broadcast an audio stream to an unlimited number of Bluetooth audio sink devices. Bluetooth audio broadcasts can be open, allowing any in-range sink device to participate, or closed, permitting only those sink devices with the correct passkey to participate.
Auracast™ broadcast audio opens significant new opportunities for innovation. “I think we won’t truly appreciate how useful broadcast audio will be until people are using it every day,” said Chris Church, senior staff engineer with Qualcomm Technologies, Inc. “Much like when your internet goes down, when you start to experience a network without broadcast audio in a few years time, you’ll quickly wonder where has it gone and how did you manage to live without it for so long?”
Auracast™ Broadcast Audio for Assistive Listening
Auracast™ broadcast audio will also support new capabilities for Bluetooth® hearing aids, and it will become an advanced, new assistive listening system (ALS) that will be significantly easier and lower cost to deploy while offering higher audio quality and greater privacy.
Auracast™ broadcast audio will overcome the challenges of traditional ALS solutions by using a familiar, proven technology ubiquitous in most consumer audio devices. It will provide the added benefits of enabling broader deployment and increased availability of ALS for people with hearing loss while expanding applicability of these systems to consumers with all levels of hearing health.
“12 years ago, when I fell overnight into the world of hearing loss, I knew that I, and everyone with hearing loss, needed some sort of way to connect wirelessly to all the devices in our world. And finally, we’re getting a solution that does it. I just want to thank everyone involved in this wonderful effort…You did a great job.”

LE Audio Products
Qualification for Bluetooth® products seeking to add support for LE Audio is now enabled. Initial consumer products supporting LE Audio, including those with Auracast™ broadcast audio, are expected to come to market in the coming months, and the Bluetooth SIG anticipates LE Audio product availability to ramp up as we approach the end of the year. “We don’t really know how it’s going to all come together in this new ecosystem, but the sky’s the limit, and I’m looking forward to all the innovations that will come,” said Jeff Solum, wireless system architect with Starkey Hearing Technologies.
