Windows 10 includes support for the Dolby Digital Plus Portable Mode, which is a dynamic range control setting that is optimized for playback over built-in speakers and headphones. Dolby content will play back louder and clearer with a dynamic range more appropriate for portable devices. This improves the experience from Windows 8 where content could occasionally render softly over built-in speakers and headphones, and the advantages will apply equally to websites running in Microsoft Edge.
Dolby Audio is compatible with current DASH (MP4) and HLS (M2TS) file formats, and so can be included with progressive download HTML5 content, adaptive streaming HLS or MSE/EME MP4 content.
