Path
====
Source: DXSDK\Samples\Multimedia\VBSamples\DirectSound\DefferedEffects
Executable: DXSDK\Samples\Multimedia\VBSamples\DirectSound\Bin
User's Guide
============
- make sure a sound file is loaded (can be WAV)
- by default, no FX are enabled. try playing the sound to see what it
orginally sounds like.
- enable one or more FXs by adding them to the 'In use' listbox
- Click Apply to call AcquireResources and load the effects (the listbox will now show
you were they were allocated, ie hardware or software).
- Hit play to hear the FX applied.
Programming Notes
=================
Fill one or more DSEFFECTDESC structs, and pass them into DirectSoundSecondaryBuffer.SetFX,
and then call AcquireResources before playing the buffer.
