如何使辅助 DirectBuffer 声音

我正在尝试从简单的点击键盘中获取声音。看起来像一个小鼓机。如果 DirectSound 不是执行此操作的正确方法，请提出其他建议。在我的代码中，我不知道出了什么问题。这里没有错误检查和翻译：

//Declaring the IDirectSound object
IDirectSound* device;
DirectSoundCreate(NULL, &device, NULL);
device->SetCooperativeLevel(hWnd, DSSCL_NORMAL );
/* Declaring secondary buffers */
IDirectSoundBuffer* kickbuf;
IDirectSoundBuffer* snarebuf;
/* Declaring .wav files pointers
   And to structures for reading the information int the begining of the .wav file */
FILE* fkick;
FILE* fsnare;
sWaveHeader kickHdr;
sWaveHeader snareHdr;

结构 sWaveHeader 是这样声明的：

typedef struct sWaveHeader
{
char            RiffSig[4];        // 'RIFF'
unsigned long   WaveformChunkSize; // 8
char            WaveSig[4];        // 'WAVE'
char            FormatSig[4];      // 'fmt '
unsigned long   FormatChunkSize;   // 16
unsigned short  FormatTag;         // WAVE_FORMAT_PCM
unsigned short  Channels;          // Channels
unsigned long   SampleRate;
unsigned long   BytesPerSec;
unsigned short  BlockAlign;
unsigned short  BitsPerSample;
char            DataSig[4];        // 'data'
unsigned long   DataSize;
} sWaveHeader;

文件打开.wav

#define KICK "D:/muzic/kick.wav"
#define SNARE "D:/muzic/snare.wav"
fkick = fopen(KICK, "rb")
fsnare = fopen(SNARE, "rb")

在这里，我做了一个函数，它为 snarebuf* 和 **kickbuf 做共同的工作

int read_wav_to_WaveHeader (sWaveHeader* , FILE* , IDirectSoundBuffer* ); // The declaring

但是我不会写这个函数，只是展示它与kickbuf一起工作的方式，例如。

fseek(fkick, 0, SEEK_SET); // Zero the position in file
fread(&kickHdr, 1, sizeof(sWaveHeader), fkick); // reading the sWaveHeader structure from file

下面检查是否适合 sWaveHeader 结构：

if(memcmp(pwvHdr.RiffSig, "RIFF", 4) ||
       memcmp(pwvHdr.WaveSig, "WAVE", 4) ||
       memcmp(pwvHdr.FormatSig, "fmt ", 4) ||
       memcmp(pwvHdr.DataSig, "data", 4))
   return 1;

声明缓冲区的格式和描述符并填充它们：

DSBUFFERDESC bufDesc;
WAVEFORMATEX wvFormat;
ZeroMemory(&wvFormat, sizeof(WAVEFORMATEX));
    wvFormat.wFormatTag     = WAVE_FORMAT_PCM;
    wvFormat.nChannels      = kickHdr.Channels;
    wvFormat.nSamplesPerSec = kickHdr.SampleRate;
    wvFormat.wBitsPerSample = kickHdr.BitsPerSample;
    wvFormat.nBlockAlign    = wvFormat.wBitsPerSample / 8 * wvFormat.nChannels;
ZeroMemory(&bufDesc, sizeof(DSBUFFERDESC));
    bufDesc.dwSize = sizeof(DSBUFFERDESC);
    bufDesc.dwFlags = DSBCAPS_CTRLVOLUME | 
                      DSBCAPS_CTRLPAN |
                      DSBCAPS_CTRLFREQUENCY;
    bufDesc.dwBufferBytes = kickHdr.DataSize;
    bufDesc.lpwfxFormat = &wvFormat;

好吧，创建缓冲区：

device->CreateSoundBuffer(&bufDesc, &kickbuf, NULL); // Any mistakes by this point?

现在锁定缓冲区并向其中加载一些数据。此数据在 WAVE 文件中的 sizeof(sWaveHeader( 字节之后开始，我错了吗？

LPVOID Ptr1;     // pointer on a pointer on a First block of data 
LPVOID Ptr2;     // pointer on a pointer on a Second block of data
DWORD Size1, Size2;  // their sizes

现在调用 Lock(( 方法：

kickbuf->Lock((DWORD)LockPos, (DWORD)Size,
                             &Ptr1, &Size1,
                             &Ptr2, &Size2, 0);

加载数据(可以吗？

fseek(fkick, sizeof(sWaveHeader), SEEK_SET);
fread(Ptr1, 1, Size1, fkick);
    if(Ptr2 != NULL)
        fread(Ptr2, 1, Size2, fkick);

解锁缓冲区：

kickbuf->Unlock(Ptr1, Size1, Ptr2, Size2);

设置音量：

kickbuf->SetVolume(-2500);

然后我做了一个wile(1(循环：1. 要求按键2. 如果按下：

kickbuf->SetCurrentPosition(0)
kickbuf->Play(0,0,0);

但是没有声音播放，请说，在我的代码中或整个概念中什么是不合适的。谢谢。
