ISpatialAudioClient interface

[Some information relates to pre-released product which may be substantially modified before it's commercially released. Microsoft makes no warranties, express or implied, with respect to the information provided here.]

The ISpatialAudioClient interface enables a client to create audio streams that emit audio from a position in 3D space. This interface is a part of Windows Sonic, Microsoft’s audio platform for more immersive audio which includes integrated spatial sound on Xbox and Windows.

Members

The ISpatialAudioClient interface inherits from the IUnknown interface. ISpatialAudioClient also has these types of members:

The ISpatialAudioClient interface has these methods.

Remarks

Get an instance of this interface by calling ActivateAudioInterfaceAsync, using the __uuidof operator to get the class ID of the ISpatialAudioClient interface. The following example code shows how to initialize this interface.

PROPVARIANT var; 
PropVariantInit(&var);  
auto p = reinterpret_cast<SpatialAudioClientActivationParams *>(CoTaskMemAlloc(sizeof(SpatialAudioClientActivationParams)));  
if (nullptr == p) { ... } 
p->tracingContextId = /* context identifier */;  
p->appId = /* app identifier */;  
p->majorVersion = /* app version info */;  
p->majorVersionN = /* app version info */;
var.vt = VT_BLOB;
var.blob.cbSize = sizeof(*p);
var.blob.pBlobData = reinterpret_cast<BYTE *>(p); 
hr = ActivateAudioInterfaceAsync(device, __uuidof(ISpatialAudioClient), &var, ...);
// ...
ropVariantClear(&var);

To access the ActivateAudioIntefaceAsync, you will need to link to mmdevapi.lib.
