对于将录音保存在WAV文件的工作主要是由CwaveFile类来完成.下面是该类的定义:
//
// Encapsulates reading or writing sound data to or from a wave file
//-----------------------------------------------------------------------------
class CWaveFile
{
public:
WAVEFORMATEX* m_pwfx; // Pointer to WAVEFORMATEX structure
HMMIO m_hmmio; // MM I/O handle for the WAVE
MMCKINFO m_ck; // Multimedia RIFF chunk
MMCKINFO m_ckRiff; // Use in opening a WAVE file
DWORD m_dwSize; // The size of the wave file
MMIOINFO m_mmioinfoOut;
DWORD m_dwFlags;
BOOL m_bIsReadingFromMemory;
BYTE* m_pbData;
BYTE* m_pbData
