- Description
- ===========
- The Play3DSound sample shows how to create a 3-D sound buffer and
- manipulate its properties. It is similar to the 3DAudio sample but does not
- use an audiopath.

- User's Guide
- ============
- Click Sound... and load a wave file. Play the Buffer. The position of the
- sound source is shown as a triangle on the graph, where the x-axis is from
- left to right and the z-axis is from bottom to top. Change the range of
- movement on the two axes by holding down the mouse button and moving the mouse.
-
- The listener is located at the center of the graph, and has its default
- orientation, looking along the positive z-axis; that is, toward the top of
- the screen. The sound source can move to the listener's left and right and to
- the listener's front and rear, but does not move above and below the listener.

- Programming Notes
- =================
-
- * To create a DirectSound3DBuffer object
- 1. Fill out a DSBUFFERDESC struct with
- DSBCAPS_CTRL3D and the 3D virtualization guid
- 2. Call DirectSound.CreateSoundBufferFromFile passing in the DSBUFFERDESC
- This will create a secondary buffer with 3D control.
- 3. Call DirectSoundSecondaryBuffer.Get3DBuffer to query for the
- DirectSound3DBuffer
-
- * Set the postion of the 3D buffer
- 1. Call DirectSound3DBuffer.SetPosition
