audio stack

About this tag
The Windows audio stack has historically forced a trade-off between high-fidelity stereo playback and clear microphone audio, particularly over Bluetooth. Recent Windows 11 updates introduce support for Bluetooth LE Audio and the LC3 codec, enabling super-wideband stereo voice and simultaneous high-quality game audio without the muffled mono degradation of older Hands-Free Profile implementations.
