About the Dolby Audio Room

The Dolby Audio Room was built using WebGL to provide an interactive environment where users can explore and play content on a variety of media devices (a media PC, desktop, laptop and tablet). Each device demonstrates Dolby Audio with a different streaming video, either MPEG DASH H.264 or HLS. The demo currently requires Microsoft Edge, since it is the first browser to include native support for Dolby Audio.

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.

Dolby Audio is compatible with current MP4 DASH and HLS file formats, and so can be included with progressive download HTML5 content, adaptive streaming HLS or MSE/EME MP4 content. It works well with both AVC/H.264 and HLS video formats.

Browser Capabilities

Dolby Audio offers superior performance, but isn’t currently supported by all browsers. Websites that use it should feature detect on the format and be prepared to stream alternative audio formats on systems that don’t support Dolby Audio. A common fallback format would be AAC audio.

JavaScript examples to check for Media Source Extension format support are listed below.

For MSE:

var test = MediaSource.isTypeSupported ('audio/mp4; codecs="ec-3"'); //Dolby EC-3
var test = MediaSource.isTypeSupported ('audio/mp4; codecs="ac-3"'); //Dolby AC-3
var test = MediaSource.isTypeSupported ('video/mp4; codecs="avc1.42E01E"'); //H.264(AVC1)
var test = MediaSource.isTypeSupported ('video/mp4; codecs="avc3"'); //H.264(AVC3)
