What is Spatial Sound?
As Microsoft's
developer documentation puts it, Windows Sonic is a "platform-level solution for spatial sound support on Xbox on Windows." Application developers can use spatial sound
APIs to "create audio objects that emit audio from positions in 3D space." All applications can take advantage of this—new UWP apps, traditional Windows desktop applications, standard PC games, and Xbox One games.
This is exactly the data that
Dolby Atmos-enabled receivers need to mix their spatial sound, so Windows Sonic enables full Dolby Atmos support in the latest versions of Windows 10. When paired with a Dolby Atmos-enabled receiver and speaker system, sounds you hear can be positioned in 3D space—vertically as well as horizontally—for an improved surround sound experience.
So, for example, if a sound is coming from above you and to your right in a movie, TV show, or video game, the upwards-firing or ceiling mounted speakers on the right side of your room will place the sound in that location—assuming you have Dolby Atmos.
