IDirectSound3DBuffer Interface

The IDirectSound3DBuffer interface provides access to the 3D parameters of a sound buffer. This interface is not supported by all sound buffers.

This section describes how your applications can obtain a pointer to an IDirectSound3DBuffer interface and manage buffer parameters by using interface methods. The following topics are discussed:

·Obtaining an IDirectSound3DBuffer Interface Pointer

·Batch Parameter Manipulation

·Minimum and Maximum Distance Values

·Operation Mode

·Position and Velocity

·Sound Projection Cones
