Understanding LE Audio: A Game Changer for Microsoft Teams
LE Audio is reshaping how wireless audio works in Microsoft Teams by resolving the age-old compromise between sound quality and microphone functionality. Let’s break down its technology, benefits, and what’s needed to make it work.
What is Bluetooth LE Audio?
Bluetooth LE Audio is a technology that streams audio over an isochronous transport to LE-enabled devices. Introduced with Bluetooth version 5.2, it uses an isochronous adaptation layer (ISOAL) to create a dedicated, time-sensitive pathway for audio data. At its core is the LC3 codec, a low-power codec designed to deliver high-quality audio with impressive efficiency.
One standout feature is Multi-Stream Audio, which sends multiple synchronized audio streams. This improves stereo performance and makes transitions between audio sources smoother. Another key feature, Broadcast Audio (Auracast), allows a single audio source to broadcast multiple streams to an unlimited number of Bluetooth-enabled devices. This approach replaces older Bluetooth Classic Audio profiles, such as A2DP (which prioritized high-quality playback but lacked microphone access) and HFP (which supported microphones but reduced audio to mono). With LE Audio, users no longer need to choose between great sound and microphone functionality.
Benefits of LE Audio for Teams Users
For Teams users, LE Audio significantly upgrades productivity and call quality. One major improvement is the ability to maintain "super wideband stereo" audio quality at a 32kHz sample rate – even while using the microphone. This is a leap forward from traditional HFP profiles, which only offered audio quality ranging from 8kHz to 16kHz.
Another advantage is its energy-efficient design. The LC3 codec provides excellent sound quality even at lower data rates, which helps extend battery life. LE Audio also introduces new profiles like the Telephony and Media Audio Profile (TMAP) and the Hearing Access Profile (HAP). These profiles allow seamless handling of both media playback and microphone use, ensuring consistent performance during meetings. Additionally, they enhance accessibility for users relying on hearing aids or other assistive listening devices.
Hardware and Software Requirements
To use LE Audio, both hardware and software must meet specific requirements. Your Windows device and headset must support LE Audio, and the operating system needs to be Windows 11, version 22H2 (KB5026446) or later. Organizations still running Windows 10 will need to plan an upgrade to take advantage of these improvements.
Beyond the operating system, the computer’s Bluetooth hardware and audio devices must also support LE Audio standards. Many newer business laptops and desktops already include compatible Bluetooth chipsets. However, older systems might require USB Bluetooth adapters designed for LE Audio.
