Applications use the methods of the IDirectSound3DListener interface to retrieve and set parameters that describe a listener's position, orientation, and listening environment in 3D space. This section is a reference to the methods of this interface. For a conceptual overview, see IDirectSound3DListener Interface.
The methods of the IDirectSound3DListener interface can be organized into the following groups:
Batch parameter GetAllParameters
manipulation SetAllParameters
Deferred settings CommitDeferredSettings
Distance factor GetDistanceFactor
Doppler factor GetDopplerFactor
Orientation GetOrientation
Position GetPosition
Rolloff factor GetRolloffFactor
Velocity GetVelocity
The IDirectSound3DListener interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
