板上各位前輩大家好    小弟最近參考一些資料寫一個希望能讀取Media Player播放時能夠讀取播放    音訊資料的程式但是我不太清楚如何能夠把資料可讀去取來希望大家幫個忙   [code]   #include < mmsystem.h >        class AudioCap   {   private:      HWAVEIN   hWaveIn;      WAVEHDR*  WaveHeaders;      WAVEFORMATEX  waveFormat;         int       buff;      int       buffers;      int       buffer_size;      int       WaveBufSize;      WAVEHDR*  SendHeader;   public:      AudioCap();      ~AudioCap();      void start();      };      AudioCap::AudioCap()   {      buffers = 2;      buffer_size = 1024;      buff = 0;      waveFormat.wFormatTag = WAVE_FORMAT_PCM;      waveFormat.nChannels = 1;      waveFormat.nSamplesPerSec = 44100;      waveFormat.wBitsPerSample = 16;      waveFormat.nBlockAlign =           waveFormat.wBitsPerSample/8*waveFormat.nChannels;      waveFormat.nAvgBytesPerSec =        waveFormat.nBlockAlign*waveFormat.nSamplesPerSec;      WaveHeaders = new WAVEHDR[buffers];      WaveBufSize       =buffer_size*waveFormat.wBitsPerSample/8*waveFormat.nChannels;      for( int i = 0; iMessageBox( "Error", "Multimedia Error", MB_OK); Application->Terminate(); } } if( waveInStart( hWaveIn ) == MMSYSERR_NOERROR ) { SendHeader = &WaveHeaders[buffers/2]; buff = 0; } else { Application->MessageBox( "Error", "Multimedia Error", MB_OK); Application->Terminate(); } } else { Application->MessageBox( "Error", "Multimedia Error",MB_OK); Application->Terminate(); } }

AudioCap::~AudioCap() {    MMRESULT res=waveInReset( hWaveIn );    for( int i = 0; ilpData); buff ; if( buff==buffers ) buff=0; SendHeader->dwBufferLength=WaveBufSize; SendHeader->dwFlags=0; SendHeader->dwLoops=0; ::waveInPrepareHeader( hWaveIn,SendHeader,sizeof(WAVEHDR)); ::waveInAddBuffer( hWaveIn,SendHeader,sizeof(WAVEHDR)); if ( SendHeader==&WaveHeaders[buffers-1]) SendHeader = &WaveHeaders[0]; else SendHeader ; }

您好:    PO程式碼的方式與版規說明請參考下面連結,煩請修改謝謝您的配合 >
