Microsoft to improve Bluetooth, add AAC support in upcoming Windows 10 update Along with AAC support, Windows will better handle how it shows Bluetooth devices in the audio menu According to The Verge, Windows 10 will finally get support for the Advanced Audio Coding (AAC) codec over Bluetooth. That means Windows users will be able to use more Bluetooth headphones and speakers. Plus, AAC should unlock better audio quality for those using Apple headphones and iTunes or Apple Music on Windows. Windows 10 currently supports the SBC and AptX codecs, but expanding support to AAC is a great move. On top of AAC support, Microsoft will also improve how Windows 10 handles Bluetooth inputs. Currently, Windows will show multiple devices for different Bluetooth profiles — for example, with the Surface Headphones connected to a Windows 10 device, you might see them in the audio menu labelled as ‘Headset’ and ‘Headphones’ depending on whether you want to take a call or listen to music.
