About the Audio Experience
This virtual demo environment was built using WebGL to provide users a way to explore and play content on a variety of media devices, including a media PC, desktop, laptop, and tablet. Each device demonstrates Dolby Atmos with a different delivery format, either MPEG-DASH, MP4, or HLS. The demo currently requires Microsoft Edge™, the first browser to include native support for Dolby Atmos. Before running the demo, make sure Dolby Atmos is enabled on your PC or laptop by selecting “Dolby Atmos for Headphones” or “Dolby Atmos for home theater” as the spatial sound option in your playback device settings.
About Dolby Atmos
Dolby Atmos extends and is compatible with the multichannel Dolby Digital Plus™ audio format, which provides crisp, clear audio in a broad range of channel configurations. Rather than being constrained to channels, Dolby Atmos uses audio objects to deliver sound that seems to emanate from every angle, even from above and behind. Dolby Atmos in Microsoft Edge can be experienced through headphones or through connected Dolby Atmos enabled receivers and sound bars. Dolby Atmos content on the PC platform is compatible with Dolby Digital Plus, so you’ll be able to enjoy your entertainment on any PC running Microsoft Edge or Apple® Safari®, though without the benefits of overhead and precision sound in Dolby Atmos.
Dolby Atmos is compatible with current MP4, MPEG-DASH, and HLS formats, so it 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.
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.
