Microsoft Spatial Sound is Microsoft’s platform-level solution for spatial sound support on Xbox, Windows and HoloLens 2, enabling both surround and elevation (above or below the listener) audio cues. Spatial sound can be leveraged by Windows desktop (Win32) apps as well as Universal Windows Platform (UWP) apps on supported platforms.

This documentation is targeted for a developer audience. For end-user support for enabling spatial sound on your device, see How to turn on spatial sound in Windows 10.

Microsoft Spatial Sound is Microsoft’s platform-level solution for spatial sound support on Xbox, Windows and HoloLens 2, enabling both surround and elevation (above or below the listener) audio cues. Spatial sound can be leveraged by Windows desktop (Win32) apps as well as Universal Windows Platform (UWP) apps on supported platforms. The spatial sound APIs allow developers to create audio objects that emit audio from positions in 3D space. Dynamic audio objects allow you to emit audio from an arbitrary position in space, which can change over time. You can also specify that audio objects emit sound from one of 17 pre-defined static channels (8.1.4.4) that can represent real or virtualized speakers. The actual output format is selected by the user, and can be abstracted from Microsoft Spatial Sound implementations; audio will be presented to existing speakers, headphones, and home theater receivers without needing any code or content changes. The platform fully supports real-time Dolby Atmos encoding for both HDMI and stereo headphone output, DTS:X for Headphones, and Windows Sonic for Headphones encoding for stereo headphones. Finally, Microsoft Spatial Sound apps abide by the system mixing policy, and their audio will also be mixed with non-spatially aware apps. Microsoft Spatial Sound support is also integrated into Media Foundation; apps that use media foundation can successfully play Dolby Atmos content with no additional implementation.

Spatial sound with Microsoft Spatial Sound supports TVs, home theaters, and sound bars that support Dolby Atmos. Spatial sound can also be used with any pair of headphones the consumer may own, with audio rendered by the platform using Windows Sonic for Headphones, Dolby Atmos for Headphones, or DTS Headphone:X.

Enabling Microsoft Spatial Sound

Whether as a developer or a consumer, a user must enable Microsoft Spatial Sound on their device in order to hear spatialized sound.

Windows

On Windows PCs, this is done via the properties page for a given sound output device. From the Sound control panel, select an output device and click Device properties. In the Spatial sound section of the page, if the device supports spatial sound, you can select one of the available formats from the Spatial sound format dropdown.

You can also enable Microsoft Spatial Sound by right-clicking the Volume icon in the taskbar.

Xbox One

On Xbox One, Microsoft Spatial Sound capabilities are always available for the consumer, and are enabled via the Settings App under General -> Volume & audio output.

After Dolby Atmos for home theater is selected as a “Bitstream format”, support for this format is checked via HDMI Extended Display Identification Data (EDID). If the HDMI device does not support the format, an error message is displayed to the user. Note that selecting this option the first time requires the user download the Dolby Access app.

If a format other than 'Bitstream out' is selected for HDMI audio then the Bitstream format dropdown is disabled.

Select Dolby Atmos for Headphones, DTS Headphone:X, or Windows Sonic for Headphones from the Headset format dropdown under Headset audio

When Microsoft Spatial Sound is not available (for instance, when playing to embedded laptop stereo speakers, or if the user has not explicitly enabled Microsoft Spatial Sound per above), the number of available dynamic objects returned by ISpatialAudioClient::GetMaxDynamicObjectCount to an application will be 0.

HoloLens 2

On HoloLens 2, Microsoft Spatial Sound is enabled by default and uses hardware DSP offload designed specifically for Windows Sonic for Headphones.

Microsoft Spatial Sound and Audio Middleware

Many app and game developers use third party audio rendering engine solutions, which often include sophisticated authoring and auditioning tools. Microsoft has partnered with several of these solution providers to implement Microsoft Spatial Sound in their existing authoring environments. This will frequently mean the APIs discussed here are abstracted from the app’s view; they are wrapped as digital signal processing (DSP) plug-ins that the app can instantiate, and which the app’s audio implementer can use to mix to a Microsoft Spatial Sound channel bed, submix, or send individual voices to dynamic object instance plug-ins as desired. Consult with your audio middleware solution provider for their level of support for Microsoft Spatial Sound.

Microsoft Spatial Sound for Audio Renderers

Many audio renderers target a Windows Audio Session API (WASAPI) IAudioClient endpoint, where the application feeds buffers of mixed and format-conformed audio data to a WASAPI audio sink; the delivered buffers are then consumed for mixing with other clients, final system-level processing, and rendering.

Microsoft Spatial Sound spatial endpoints are implemented as ISpatialAudioClient, which has many similarities to IAudioClient. It supports static sound objects forming a channel bed, with support for up to 8.1.4.4 channels (8 channels around the listener – Left, Right, Center, Side Left, Side Right, Back Left, Back Right, and Back Center; 1 low frequency effects channel; 4 channels above the listener; 4 channels below the listener). And it supports dynamic sound objects, which can be arbitrarily positioned in 3D space.

The general implementation coding pattern for ISpatialAudioClient is:

Create static and/or dynamic audio objects.
Feed each object’s audio buffer each frame so the system can render it.
Update dynamic objects’ 3D positions on demand – as frequently (or infrequently) as the app desires.

Note that the current output format (speakers or headphones; Windows Sonic for Headphones, Dolby Atmos, or DTS Headphone:X) is abstracted from the above implementation – the app developer can focus on spatial sound without needing to pivot based on format. Apps that do want their behavior to diverge based on output format can query the format in use, but the abstraction means an app is not required to handle these formats.

Microsoft Spatial Sound Integration with Audio Renderers

Because ISpatialAudioClient is an audio sink that consumes data, an audio renderer has several options for how to interact with and deliver audio data to it. There are three commonly used integration techniques (and for titles using audio middleware, you may see equivalent plug-ins made available based on these options):

7.1.4 panners and mastering voice: Renderers that already support 7.1 endpoints may opt to simply add support for the four additional height channels that the ISpatialAudioClient static channel bed supports. Any channel panning they previously did (likely already leveraging x,y, z co
