LE Audio typically the next generation of Bluetooth audio will enhance the performance of Bluetooth audio, add support for hearing aids, and introduce Audio Sharing, an innovative new Bluetooth use case with the potential to once again change the way we experience audio and connect with the world around us
Key Features :
- LC3 Codec
- Multi-Stream Audio
- Audio Sharing (Using Broadcast Audio)
- Support for Hearing aids
LE Audio will include a new high-quality, low-power audio codec, the Low Complexity Communications Codec (LC3). Providing high quality even at low data rates, LC3 will bring tremendous flexibility to developers, allowing them to make better design tradeoffs between key product attributes such as audio quality and power consumption.
Tests have shown that LC3 will provide improvements in audio quality over the SBC codec included with Classic Audio, even at a 50% lower bit rate. Developers will be able to leverage this power savings to create products that can provide longer battery life or, in cases where current battery life is enough, reduce the form factor by using a smaller battery
Multi-Stream Audio will enable the transmission of multiple, independent, synchronized audio streams between an audio source device, such as a smartphone, and one or more audio sink devices. It uses LE Isochronous Channels for time-synchronized processing. It enables support for voice control services, multiple audio sources, etc..
LE Audio for Bluetooth Hearing Aids
LE Audio will enable the development of Bluetooth hearing aids that bring all the benefits of Bluetooth audio to the growing number of people with hearing loss. With its low power, high quality and multi-stream capabilities, LE Audio adds support for Hearing Aids.
Audio Sharing(Broadcast Audio)
LE Audio will also add Broadcast Audio, enabling an audio source device to broadcast one or more audio streams to an unlimited number of audio sink devices. Broadcast Audio opens significant new opportunities for innovation, including the enablement of a new Bluetooth use case, Audio Sharing.
Bluetooth Audio Sharing can be personal or location-based. With personal audio sharing, people will be able to share their Bluetooth audio experience with others around them. With location-based audio sharing, public venues such as airports, bars, gyms, cinemas, and conference centers can now share Bluetooth audio that augments the visitor experience
LE Audio will enhance the performance of Bluetooth audio and with sharing feature the usage is limitless.
