This sample is a DirectSound streaming test. It illustrates streaming data from a disk WAVE file to a DirectSound secondary buffer for playback.
This sample illustrates how to play a long sound using a streaming DirectSoundBuffer. Because of this design, it may not work correctly when using very short sounds, such as 1 or 2 seconds long. Those files are more appropriate for static buffers; see DirectSound Mixing Test (DSshow) for examples of how to code such buffers.
There are buttons to play and stop the WAV file, and a check box to indicate whether the file should be looped or not. Regardless of the check box setting, the DirectSoundBuffer will be played with looping since a streaming buffer is being used.
There are sliders to control the sound's frequency, pan, and volume settings. In addition, there is a slider indicating the progress through the sound data.
On the Options menu, you can toggle Enumerate Drivers, to show what objects DirectSoundEnumerate will list for you.
