Microsoft has made significant strides in enhancing Bluetooth audio quality with the latest update to Windows 11, specifically in the 24H2 version. This improvement is particularly noticeable for users who engage in voice chats and video calls using Bluetooth headsets or earbuds. In a recent blog post, the company unveiled an upgrade to Bluetooth LE Audio streaming, introducing a feature known as super wideband stereo.
Enhanced Audio Experience
This innovative feature empowers compatible Bluetooth devices to deliver super wideband audio in stereo mode while simultaneously utilizing the device’s internal microphone. For those who frequently rely on Bluetooth headsets for voice and video communication, this upgrade represents a substantial enhancement. Previously, when using Bluetooth LE audio in the 32kHz sample rate “super wideband” mode, users were forced to downgrade to mono mode whenever the integrated microphone was activated. Mono mode, while functional, only offers single-channel sound, which lacks the depth needed for a rich audio experience.
With Microsoft’s new super-wideband stereo mode, users can now enjoy stereo sound regardless of whether the microphone is in use. This advancement ensures that audio remains vibrant and immersive during conversations, enhancing the overall communication experience.
Compatibility and Future Features
While this update does not render existing 2.4GHz wireless gaming headsets obsolete—given that latency will still be a factor—it does ensure that audio remains in stereo, providing a more engaging experience. To take advantage of this feature, users will need a Bluetooth audio device that supports LE Audio. Additionally, it is important to note that this feature is exclusive to Windows 11 24H2 and newer versions, necessitating an update to the latest Windows iteration for access.
In tandem with these audio enhancements, Microsoft is also rolling out spatial audio capabilities within Microsoft Teams. This feature introduces 3D audio during Teams calls, allowing users to perceive sound based on the location of speakers on their screens. According to Microsoft, this situational awareness fosters better engagement during calls, leveraging the “cocktail party” effect to help users focus on conversations more effectively.
