As the world passes through unprecedented times, new technologies are constantly emerging to make our lives easier and more connected. One such technology is Auracast, a revolutionary Bluetooth audio sharing technology that has taken the world by storm.
But what exactly is Auracast? How does it work? And what makes it stand out from other similar technologies? Today, we will explore all these questions and more to help you understand Auracast in depth.
Definition
Auracast is one of the novel features included as one of the latest specifications for Bluetooth LE (Low Energy) Audio standards. It allows seamless sharing of audio between multiple devices, without additional apps or pairing processes.
Simply put, Auracast is a Bluetooth feature that lets a source device, like a TV or phone, broadcast audio streams to unlimited receivers like earbuds, speakers, or hearing aids. Users can then select which audio stream they want to tune into.
History
Firstly introduced in 2018, Auracast is actually a rebranded version of a feature introduced earlier by Bluetooth Special Interest Group (SIG) called “Audio Sharing”.
However, Auracast offers several improvements and enhancements over its predecessor, making it a more user-friendly and efficient technology. The Bluetooth SIG compares the technology to radio signal transmission: a standard radio transmitter broadcasts a signal that multiple in-range receivers can tune into.
How it works
Auracast uses Bluetooth Low Energy to transmit audio streams from a source device to multiple receivers. This means the source device and the receivers do not need to be paired, resulting in a seamless and hassle-free sharing experience.
Once enabled, the source device will start broadcasting the audio stream through Auracast packets to all available receivers within its range. The receivers can then detect these packets and allow users to select which audio stream they want to tune into.
Features
1) Multi-Device Connectivity
One of the standout features of Auracast is its ability to connect to multiple devices simultaneously. This means you can stream audio from your TV to your earbuds, speakers, or hearing aids simultaneously.
The devices must support Bluetooth 5.2 or later, and the PBP spec within LE Audio must be Auracast compatible, allowing easy connection and switching without extra pairing.
2) Low Latency
Auracast offers extremely low latency, meaning there is minimal delay between the audio being broadcast and received by the receivers.
This makes it ideal for real-time applications like watching TV or gaming.
3) Energy Efficient
As its name suggests, Auracast uses Bluetooth Low Energy technology, making it an energy-efficient option for streaming audio.
This means longer battery life for both the source device and receivers.
4) Wide Radius of Coverage
Auracast has an impressive range, allowing it to broadcast audio to receivers within a wide radius. This makes it perfect for events or gatherings where multiple people can tune in to the same audio stream.
It is said that an Auracast transmitter can be picked up approximately 30,000 square feet radius (2787 square meters), making it a convenient option for outdoor events.
Future Potential for Hearing Aids
Auracast technology has the potential to revolutionise the hearing aid industry. With its multi-device connectivity and low latency features, it could provide a more seamless and enhanced audio experience for those with hearing impairments.
Additionally, Auracast could also eliminate the need for separate receivers or transmitters typically required for traditional hearing aids, making them more discreet and user-friendly.
Takeaway
Auracast is a revolutionary Bluetooth audio sharing technology that offers multi-device connectivity, low latency, energy efficiency and wide coverage. It has the potential to revolutionise various industries, including home entertainment and hearing aids.
With its seamless and hassle-free streaming experience, Auracast is set to change the way we share and consume audio content, especially for hearing aids users.
