On Thursday, Microsoft announced Build 2137 of Windows 10 Insider Preview. The beta version of the OS brings a couple of new features as well as a plethora of bug fixes.
The most notable feature that the new build brings is the support for the Advanced Audio Codec (AAC) over Bluetooth. AAC can deliver high-quality audio at a lower bitrate. Since this codec uses lower data, it is ideal for online audio streaming even with slow internet connections. Up until now, Windows had support for aptX and SBC audio codecs. AAC is the default audio codec for Apple. Moreover, this codec is also supported by Android, Sony Playstation, and Nintendo, among other products. With support for AAC, Windows 10 can now deliver better audio quality to AirPods.
Microsoft is also simplifying the audio output in Windows 10. The brand calls this feature “Unified audio endpoint.” According to the company “No more clicking through multiple audio endpoints to make your Bluetooth headset’s voice and mic work properly. We now only expose one audio endpoint in the UI and will switch to the correct one automatically for you for a seamless experience. Listening to Spotify and then have to hop onto a Teams call? You can also now directly control the volume of your headset.”
Both the features are currently a part of the Windows 10 Insider Preview 21370. These features should be added to the stable version of Windows 10 with a software update later in 2021.
