• 在 Delphi 下使用 DirectSound (18): 3D 特效



    DirectSound 3D 特效相关接口: IDirectSound3DBuffer8、IDirectSound3DListener8.

    IDirectSound3DBuffer8 是声源, 它可以有一个或多个; IDirectSound3DListener8 是听者, 它只能有一个.

    IDirectSound3DBuffer8 通过 QueryInterface() 从次缓冲获取, 要求该次缓冲建立时必须指定 DSBCAPS_CTRL3D;
    IDirectSound3DListener8 通过 QueryInterface() 从主缓冲区获取, 该主缓冲区建立时也必须指定 DSBCAPS_CTRL3D.

    "声源" 和 "听者" 可以交互变换, 也可独立变换; 只变换 "听者" 时, 提供声音的缓冲区建立时也应该指定 DSBCAPS_CTRL3D.
    IDirectSound3DBuffer8 其实只负责 3D 效果变换, 真正提供声音和播放控制的还是它之前的 IDirectSound3DBuffer 或 IDirectSound3DBuffer8.

    IDirectSound3DBuffer8 相关方法:
    {3D 音效处理模式}
    GetMode()、SetMode()
      DS3DMODE_NORMAL       = $00000000; //普通
      DS3DMODE_HEADRELATIVE = $00000001; //声源的参数是相对于听者的
      DS3DMODE_DISABLE      = $00000002; //禁用 3D 特效
    
    {最大、最小距离}
    GetMaxDistance()、SetMaxDistance()

    GetConeAngles()、SetConeAngles()
    GetConeOutsideVolume()、SetConeOutsideVolume()
    
    {一起获取或设置参数}
    GetAllParameters()、SetAllParameters()
    


    IDirectSound3DListener8 相关方法:
    {位置、速度、方向}
    GetPosition()、SetPosition()

    {距离因子、多普勒因子、滚降因子}
    GetDistanceFactor()、SetDistanceFactor() 
    GetDopplerFactor()、SetDopplerFactor()
    GetRolloffFactor()、SetRolloffFactor()
    
    {一起获取或设置参数}
    GetAllParameters()、SetAllParameters()
    
    {延迟设置}
    CommitDeferredSettings() //在使用系列 Set... 方法时, 如果指定了 DS3D_DEFERRED 参数, 则需用该方法提交参数设置;
                             //和 DS3D_DEFERRED = 1 对应的是 DS3D_IMMEDIATE = 0, 表示立即生效; 使用延迟设置更节省资源.
