User's Guide
============
Load a wave file by clicking Sound File. Select Focus and Buffer Mixing
options; note that the various settings are explained under Expected Behavior
as you select them. Click Play. If you don't hear any sound, check the Status
pane. The application might fail to create the buffer in hardware if this
option has been selected.
By using the sliders you can adjust the frequency, pan, and volume dynamically
as the buffer is playing.
Programming Notes
=================
For a simpler example of how to setup a DirectSound buffer without as many
controls, see the PlaySound sample.
To set the focus of a buffer call IDirectSound::CreateSoundBuffer with
DSBCAPS_GLOBALFOCUS or DSBCAPS_STICKYFOCUS or neither of these flags.
To set the memory location of a buffer call IDirectSound::CreateSoundBuffer
with DSBCAPS_LOCHARDWARE or DSBCAPS_LOCSOFTWARE or neither of these flags.
To control various aspects of DirectSound buffer:
To adjust the frequency call IDirectSoundBuffer::SetFrequency
To adjust the pan call IDirectSoundBuffer::SetPan
To adjust the volume call IDirectSoundBuffer::SetVolume
