Dolby Audio, Windows 10, and Microsoft Edge Deliver Great-Sounding Content

Windows® 10 is coming, and with it comes support for Dolby Audio™, both in the operating system and with the new Microsoft® Edge browser. Dolby Audio on Windows 10 PCs supports all content encoded in the Dolby Digital Plus™ format. With Microsoft Edge and the new Universal Windows Platform, it’s easy for developers and content creators to deliver Dolby Digital Plus™ encoded content for x86 Windows 10 PCs and tablets.

Don’t feel like building a proprietary app, but want to give your fans access to your content in Dolby Digital Plus over the web? No problem.

Just follow these steps to make sure that anyone viewing your content in Microsoft Edge will experience it as you intended.

Maybe you have a web series that you’d like to offer in 5.1, a Dolby Digital Plus mix of your band’s latest single, or a trailer for your upcoming film that you’d like your audience to hear in Dolby Audio—presenting that to an audience consistently across Windows 10 PCs or tablets is easily possible with a little bit of code.

With Dolby Audio, which supports the Dolby Digital Plus format, Windows 10 and Microsoft Edge users who experience your website or universal app will benefit from playback with crisp, clear dialogue and greater detail of sounds. Windows users have experienced rich, clear, and powerful audio in Windows operating systems for years, but Microsoft Edge is the first browser through which Dolby Digital Plus audio is available.

Dolby Digital Plus support in Microsoft Edge is compatible with the tools that you’re already using to deliver and protect your content, whether you’re using W3C media specific APIs, leveraging adaptive streaming or HTML 5 Media Elements, even DRM extensions like Media Source Extensions and Encrypted Media Extensions. The Dolby features in Microsoft are compatible with popular video streaming solutions like HLS and MPEG-DASH.

To see an example of this Windows 10 functionality in practice, check out Microsoft Edge Dolby Audio Room Demo from a Windows 10 PC, or check out the sample app from Dolby. You can either sideload our sample app into Windows 10 or load it into your own project and compile it yourself. Feel free to borrow whatever code you like for your own apps, too.

Once you’ve built your app, all you need is Dolby Digital Plus encoded content. If you have stereo or 5.1 content that is not yet encoded in Dolby Digital Plus, you can easily encode it using tools at, with Adobe® Premiere® Pro, or with another favorite tool for Dolby Digital Plus mixing and encoding.

If you plan on making your content available for streaming, via your new app, you can simply upload your content—including the stereo or 5.1 mix in its current format—to Microsoft Azure™, and the cloud service will take care of the encoding for you. There’s even a blog post on using Microsoft Azure to do exactly that.

Once you have an app or a compatible website and properly encoded content, you’re ready to start sharing your Dolby Digital Plus encoded content with users of Windows 10 PCs and tablets, either by streaming the content to your app, streaming it to the Microsoft Edge browser, or by allowing your fans to download your content.
