Auracast broadcast technology

Auracast is a broadcast technology supported by Bluetooth LE Audio, which is a low-energy Bluetooth standard introduced in 2022.

It allows a source device, like a smartphone or TV, to broadcast audio to an unlimited number of receivers within range, such as earbuds, speakers, or hearing aids. This means you can share audio with friends or stream to large numbers of people in public spaces, like airports or gyms.

Auracast can be secured with a password for private broadcasts, but it can also be open to the public, especially in public space.

How does Auracast compare to other audio streaming technologies?

Auracast stands out from other audio streaming technologies primarily due to its ability to broadcast audio to an unlimited number of receiver within range.

Here’s how it compares to other technologies:

• Broadcast Capability: Unlike traditional Bluetooth that connects one source to one or a few devices, Auracast can transmit to countless receivers, similar to how radio works.
  
  
• Energy Efficiency: It’s built on Bluetooth LE (Low Energy) Audio, making it more power-efficient than standard Bluetooth audio streaming.
  
  
• Audio Quality: Auracast supports the LC3 codec, which promises better audio quality at lower data rates compared to the standard SBC Bluetooth codec.
  
  
• Versatility: It can be used for personal audio experiences in public spaces, like listening to TV audio in a pub without disturbing others, or for hearing announcements in airports.
  
  
• Ease of Use: You can join Auracast broadcasts by searching for them like Wi-Fi networks, scanning a QR code, or tapping their device, similar to contactless payments.

Overall, Auracast’s unique broadcasting feature and efficiency make it a revolutionary technology in the realm of public and personal audio sharing.

In what situations can Auracast be used?

Auracast can be used in a variety of situations to enhance audio experiences. Here are some scenarios where it can be particularly useful:

• At Home: Say goodbye to TV transmitters. With Auracast, you can listen to your TV’s audio using your own headphones, creating a personal listening space without disturbing others.
  
  
• Conferences: Use your own headphones to listen to speakers at conferences, ensuring you can hear clearly even in noisy environments.
  
  
• Public Announcements: Never miss an airport or train station announcement. Auracast can transmit these directly to your hearing aids or earbuds.
  
  
• Assisted Listening: Provides better assisted listening in venues like theatres, churches, and lecture halls.
  
  
• Air Travel: Could potentially be used on airplanes for in-flight entertainment.
  
  
• Social Listening: Share music or audio content with friends or family, each using their own devices.
  
  
• Public Spaces: In places like gyms, fan parks, or waiting rooms, Auracast can broadcast audio to multiple listeners simultaneously.

These are just a few examples, and as the technology becomes more widespread, we can expect to see even more innovative uses for Auracast.

How will Auracast be used in hearing aids?

Auracast’s introduction into hearing aids is a game-changer, offering you the ability to connect to various public audio sources with ease and clarity.

Here’s how Auracast will be used in hearing aids:

• Personalised Audio Streams: You can select the audio stream you want to listen to, such as a TV channel in a gym or a lecture in a hall, directly from their smartphone, similar to selecting a Wi-Fi network.
  
  
• Public Announcements: Hearing aid wearers can receive broadcasts like airport gate announcements directly to their devices.
  
  
• Assisted Listening: In venues like theaters or churches, Auracast can provide a direct audio feed, bypassing ambient noise and improving clarity.
  
  
• Compatibility: Hearing aids that are “Auracast-ready” will only need a firmware update to enable this feature. Models like ReSound Nexia are already equipped for Auracast.

Auracast will significantly enhance the functionality of hearing aids by providing a more personalised and inclusive listening experience.
