Applications use the methods of the IDirectSound3DBuffer interface to retrieve and set parameters that describe the position, orientation, and environment of a sound buffer in 3D space. This section is a reference to the methods of this interface. For a conceptual overview, see IDirectSound3DBuffer Interface.
The methods of the IDirectSound3DBuffer interface can be organized into the following groups:
Batch parameter GetAllParameters
manipulation SetAllParameters
Distance GetMaxDistance
Operation mode GetMode
Position GetPosition
Sound projection GetConeAngles
cones GetConeOrientation
Velocity GetVelocity
The IDirectSound3DBuffer interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
