Low Energy integrated circuits appeared as early as 2009, but overcoming the hurdle of high bandwidth requirements for audio transmission took another decade of development. Bluetooth Low Energy isn’t a new technology, but Bluetooth Low Energy Audio is. These enhancements will be rolled into Bluetooth as a set of features known as LE Audio. The LE Audio solution demonstrates the benefits of High-Quality Wireless LE Audio and is designed to support the new LE Audio specifications that are expected to be released by the Bluetooth Special Interest Group (SIG) during the first half of 2020. Currently, device manufacturers must overcome single-stream limitations when they design wireless headphones. It's called LE Audio and it offers improved audio quality and lower battery use. Peter Liu This is similar to (but better than) Apple’s new “Share Audio” feature, which allows AirPods and Beats owners to share audio with two sets of headphones. Secretary General of EHIMA This can result in increased latency, patchy audio, and dropouts because both earbuds are forced onto one channel. 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. Building on the ability to serve source audio to multiple Bluetooth listening devices, you could compare the new “broadcast” feature to Wi-Fi. CTO of WiFore Consulting With personal audio sharing, people will be able to share their Bluetooth audio experience with others around them; for example, sharing music from a smartphone with family and friends. If you’ve ever wanted to host your own silent disco, Bluetooth LE Audio will make it easier than ever! The Bluetooth Special Interest Group on Monday announced at CES the latest version of Bluetooth. It will also take venues some time to catch up, but by the time they do, there should be plenty of compatible devices on the market. The Bluetooth Special Interest Group (SIG) introduced Bluetooth LE Audio on Tuesday. A couple of months ago at CES 2020 (January 2020), the Bluetooth SIG introduced the latest version of Bluetooth, version 5.2. Many products on the market, like wearables, smartphones, and medical devices, already use standard Bluetooth LE. LE Audio extends the capabilities of classic Bluetooth audio.

These streams could make it easy to tune in to foreign language audio tracks at a movie theater, or listen to the sound of a silenced TV in an airport lounge through your earphones. A: LE Audio relies on a new core feature introduced in version 5.2 of the Bluetooth Core Specification. The new codec is designed to improve performance and reduce power consumption. For example, they can provide a better stereo imaging experience, make the use of voice assistant services more seamless, and make switching between multiple audio source devices smoother.”, Nick Hunn, “Even at a 50 percent lower bit rate.”. In practice, this could allow you to do things like listen to a baby monitor, take a phone call, and use a smart assistant like Alexa, all from one set of Bluetooth headphones. Bluetooth LE Audio fully supports hearing aid development standards and could make it possible to pass audio directly from a source to a hearing aid, or even a whole room full of people with hearing aids. The Bluetooth Special Interest Group (SIG) today announced the upcoming launch of LE Audio, which is the next-generation of Bluetooth audio.LE Audio will bring enhanced Bluetooth 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. Tim Brookes is a technology writer with more than a decade of experience. Manfred Lutzky With Bluetooth LE Audio, you can connect a single pair of headphones to multiple devices at the same time. European Hearing Instrument Manufacturers Association. All Rights Reserved. A codec compresses audio for transmission over the air. It will be up to device manufacturers to implement the right technology for the job. It will support both voice call and music streaming applications, and generally extend what’s possible using Bluetooth technology. 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. As a result, within a few years most new phones and TVs will be equally accessible to users with hearing loss. The technology includes a new Bluetooth codec which aids in improving efficiency & aid the deaf and people who have difficulty hearing. How-To Geek is where you turn when you want experts to explain technology. In addition to lower energy consumption, the new Low Complexity Communications Codec (LC3 for short), which was co-developed by the Fraunhofer Institute for Integrated Circuits and Ericsson, promises improvements in audio quality over the existing SBC Bluetooth codec. For example, people will be able to select the audio being broadcast by silent TVs in public venues, and places like theaters and lecture halls will be able to share audio to assist visitors with hearing loss as well as provide audio in multiple languages. First, devices could be smaller without sacrificing runtime, and second, battery life could be improved significantly without additional size or weight.
