关键字: VB .NET  DirectX DirectSound 3D                 作者:董含君

经过一下午的奋战,走了若干弯路,终于可以播放3D声音效果了

感动 ~ ~

大体按照下列的步骤来:

1 关联设备 SetCooperativeLevel
2 设置3D硬件效果  DSoundHelper.Guid3DAlgorithmHrtfFull
3 格式要求 SoundFormat 必须是单声道,不能是立体声
4 主要缓冲区描述
5 创建Listenner
6 辅助缓冲区读取wav
7 创建3D缓冲区
8 播放
9 控制空间位置,以及设置多普勒效应因子,衰减因子
10 停止播放

以下代码注释比较全,顺序比微软的例子简单不少

由于CSDN的Blog不能上传贴图以及RAR,只能帖代码了,有两个Button 一个Picturebox,还有若干Label
