Dolby Audio in the Browser

You may already be familiar with the premium surround sound audio experience that Dolby delivers regularly to feature films in the cinema and home theater.

Playback, including Dolby Atmos precise sound rendering from any point in space around or above the listener, can be achieved over any connected headphones* or Dolby Digital Plus or Dolby Atmos enabled receiver connected to the computer via HDMI®.

Why Dolby Atmos in the Browser?

With Dolby content delivered to the browser, users can now enjoy the best in-browser entertainment experience available. Dolby Digital Plus has emerged as the primary delivery platform for high-quality connected entertainment in the living room. Many of the world’s leading content streaming services use Dolby to deliver stereo, 5.1, and 7.1 content to entertainment devices such as TVs, gaming consoles, tablets, smartphones, PCs, and smart Blu-ray players.

With the emergence of high definition video and the increasing resolution and color fidelity in computing displays, the browser visual experience has improved significantly in recent years—yet the audio experience has not—until now. With Dolby Digital Plus encoded content, supporting browsers allow content creators and developers to build web applications and stream content that take advantage of native browser functionality (i.e. without the need for plug-ins such as Flash or Silverlight).

Dolby Digital Plus is available today in Microsoft Edge (Windows 10 and above), Apple Safari 9 on OS X 10.11 (El Capitan and above), and Apple Safari 9 on iOS 9.3 and above.
