Bluetooth LE (Low Energy) Audio is an umbrella term for a range of new technologies within the bluetooth standard. The latest generation of the standard replaces the older SBC codec for the LC3 codec, which aims to improve audio quality while reducing bitrate. With an equal bitrate, the audio quality can be improved even further. A lower bitrate can lead to a longer battery life.
A completely new feature is Auracast. This is a system that allows audio to be sent to multiple receivers. Auracast makes it possible for a television to send one or more audio streams to an almost unlimited number of headphones. The user can choose the desired stream himself, via a choice such as you choose for your WiFi network, a QR code or an NFC tag. Not only a television can be used as a source. Smartphones or public address systems can also serve as Auracast transmitters.
Finally, the latest generation of Bluetooth LE Audio offers hearing aid support. These can be connected to a television, for example, after which audio is sent to the left and right hearing aids in perfect synchronization. The first devices to support the latest version of Bluetooth LE Audio will be announced later this year.
