Microsoft Announces Dolby Audio For High Performance Audio In Microsoft Edge

Microsoft Edge

Microsoft today announced that Microsoft Edge includes HTML5, MSE and EME support for a new audio format:  Dolby Audio. Dolby Audio supports the multi-channel Dolby Digital Plus audio format that provides crisp, clear audio in a broad range of channel configurations.  Microsoft Edge is the first browser to include support for Dolby Digital Plus.   Both websites and web based apps can make use of this integration.

They have added Dolby Audio to Microsoft Edge so that web apps and sites can deliver the richest and most compelling media experiences with Windows 10. In particular, we wanted Microsoft Edge to support the most demanding requirements from media websites. Supporting Dolby Audio fits with this goal.

It allows websites to match the compelling visuals of H.264 video with equally compelling multi-channel audio.  It works well with AVC/H.264 video and also with our previously announced HLS and MPEG DASH Type 1 streaming features, which both support integrated playback of an HLS or DASH manifest.

More info for developers,

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.
