7.麦克录音系统的实现(MicDemo)  

下面是该系统的界面:
 

对于录音来说最重要的就是CSoundIn类,下面就是该类的定义:

namespace perdubug {  // prevent the name-space pollution

class CSoundIn 
{
public: 
 BOOL     __initMic(); // get the best wave format supported by your sound card
                                     // and then i will use the format to capture sound.

 void     __closeMic();

 BOOL     __openMic(); // open device and begin to capture with the best format(when
                                        // invoke __initMic function then you will get the best format
                                        // supported by host's sound card
 
 //
 // if your want to capture sound and export into a wav file please invoke this function
 // to tell me the full path then i will create the wav file.
 //
 void     __createOutputWaveFile(const TCHAR * lpszFileName);
