Introduction to Auracast

Google is in the process of updating Android to support Auracast, a Bluetooth LE technology designed to enable the creation, listening, and switching between public broadcasts of Bluetooth audio on existing devices. Fundamentally, Auracast allows users to tune their Bluetooth earbuds into a muted TV in a public area and listen to its audio. However, Google appears to be primarily interested in utilizing this feature to make hearing aids more useful.

Google’s Plan for Auracast

Google intends to leverage Auracast to stream Bluetooth audio to hearing aids paired with a user’s phone or tablet. If a TV or streaming device supports Auracast, users can connect their hearing aids directly to the source via their Android device, allowing them to hear the audio being played. Moreover, any customized presets for hearing aid sound will be applied to audio heard through Auracast. On Pixel 9 devices, users can even scan a QR code to instantly connect their hearing aids, eliminating the need to navigate through settings.

Availability and Additional Features

This feature is set to arrive on the Pixel 9 through the third Android 16 beta, which is being released today. In addition to Auracast, the pre-release software includes a new accessibility option that allows users to outline text for easier reading and a "Local Network Protection" feature, giving Android 16 device users more control over app access to devices on their local network, according to Google.

Conclusion and Future Release

Although the final version of Android 16 is still pending, the developer beta is available for download today on supported devices. For those who prefer not to experiment with the beta, Google suggests trying out Auracast with a Samsung Galaxy device running One UI 7 and compatible hearing aids from GN Hearing or Starkey.
