After several years of work, the Bluetooth Special Interests Group (SIG) announces that it has completed Bluetooth LE Audio. This is a major upgrade for Bluetooth audio, adding a number of new features including a simple solution for whole-home audio.
Note: Bluetooth LE Audio is not the same as Bluetooth Low Energy. As the name suggests, this new standard focuses on audio applications. The older Bluetooth Low Energy is more focused on power consumption, especially in small devices like smartwatches and medical trackers.
The new Bluetooth LE Audio standard includes dozens of specifications, most notably the new LC3 codec (which should replace SBC). This codec increases audio quality across the board, even at low bitrates used to conserve battery life in hearing aids, headsets, and other products.
But the new Auracast system is perhaps the most exciting part of Bluetooth LE Audio. Auracast lets you cast Bluetooth to multiple audio devices simultaneously, allowing you to pair multiple headsets to a TV, for example, or turn generic Bluetooth speakers into a whole-house audio system.
Searching for “Auracast Broadcasts” should be easy — the Bluetooth SIG says it’s like searching for Wi-Fi networks. You can place passcodes for these shipments or even share them with a QR code. auracast should Also, there are some behind-the-scenes improvements to Bluetooth, such as: B. Reduced latency when using Google Assistant with earbuds.
Everyone will enjoy the unique features of Bluetooth LE Audio. But those who are hard of hearing can see the most tangible benefit. Both the LC3 codec and Auracast Broadcasts present a unique opportunity to improve hearing aid quality, battery life and price. It should also allow users to pair hearing aids to multiple devices at the same time, such as B. a game console (for game audio) and a smartphone (for podcasts or YouTube videos).
There’s just one problem with this upgrade – you probably won’t experience Bluetooth LE Audio until you buy new devices. A handful of smartphones, TVs, and audio receivers can get Bluetooth LE Audio through a software update, but the majority of products customers use today will never support Bluetooth LE Audio.
