Nov 14, 2018 - As crazy as it sounds, Dolby intends for the Dimension to be mostly kept at and used at home — really as a substitute for a lofty surround sound.
Dolby Headphone is a technology developed by Lake Technology (Australia), that later sold marketing rights to Dolby Laboratories, sometimes referred to as Mobile Surround, which creates a virtual surround sound environment in real-time using any set of two-channel stereo headphones. It takes as input either a 5.1 or a 7.1 channel signal, a Dolby Pro Logic II encoded 2 channel signal (from which 5 or 7 channels can be derived) or a stereo 2 channel signal. It sends as output a 2 channel stereo signal that includes audio cues intended to place the input channels in a simulated virtual soundstage.
Dolby Headphone is incorporated into the audio decoders packaged with surround headphones including:

Dolby Headphone is supported by various netbooks, including the Lenovo IdeaPad S10-2 and the Acer Aspire One. Certain AsusXonar soundcards also have Dolby Headphone support, including Asus Xonar models: D1, D2/PM, DX, D2X, DG, HDAV1.3, ST, STX, STX II, Xense and U3. PowerDVD Ultra 9 also supports Dolby Headphone when certain options are set in the 'Settings' menu but PowerDVD is not marketed as an official product of Dolby Headphone.
Several Nokia smartphones such as the Nokia N9 officially support Dolby Headphone, and the technology is also supported in the new version of the Nokia Belle Feature Pack 1. The functionality is either pre-installed or is available as an update for the Nokia 603, 700, 701 and 808 Pureview, and is included on many models in the Lumia series including the 810, 820, 920 and 1020.[1][2]
The technology has since been surpassed by 'Dolby Atmos For Headphones', which mainly adds the extra simulation required for the Atmos surround channels to the pre-existing technology. This converts the technology into full Binaural surround.
History[edit]
The headphone virtual surround sound technology was initially developed and marketed by Lake Technology in 1997.[3]
In October 1998, Dolby licensed the headphone surround sound technology from Lake and renamed it 'Dolby Headphone'.
On 23rd Dec 2003, Dolby Laboratories bought over Lake Technology, including the Dolby Headphone technology, for A$21.6 million.
Technology[edit]
Head-related transfer functions (HRTFs) are used to generate positional audio cues in the two-channel output signal. A finite impulse response (FIR) filter is used to process the audio with lower latency.

For the first time, Dolby Atmos® can be delivered through the browser on PCs and tablets. Give your users a crisp, clear, and immersive sound experience with Dolby Atmos.
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.
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.
