函式說明文件

int AssertWaveError ( int  source,
int  err 
)

被參考於 CloseWaveIn(), CloseWaveOut(), OpenWaveIn(), OpenWaveOut(), StartWaveIn(), 及 waveInProc().

void CloseWaveIn (  ) 

Close waveIn device.

備註:
  1. wiblIndex will be reset to 0.
  2. waveInStatus will be set to 0.

定義在 waveAPI.cpp 檔案之第 183 行.

參考 AssertWaveError(), WAVE_IN, waveInHandle, waveInHeaders, waveInStatus, wiblIndex, 及 WIBLSIZE.

void CloseWaveOut (  ) 

Close waveOut device.

備註:
Call this function after CloseWaveIn().

定義在 waveAPI.cpp 檔案之第 162 行.

參考 AssertWaveError(), WAVE_OUT, waveOutHandle, waveOutHeaders, 及 WIBLSIZE.

bool OpenWaveIn (  ) 

Open waveIn device (specified by WAVE_MAPPER).

備註:
  1. Sampling rate is pre-defined.
  2. waveInStatus will be set to 0.

定義在 waveAPI.cpp 檔案之第 51 行.

參考 AssertWaveError(), channels, format, samplingRate, WAVE_IN, waveAPIInit(), waveAPIInitialized, waveInHandle, waveInProc(), 及 waveInStatus.

void OpenWaveOut (  ) 

Open waveOut device (specified by WAVE_MAPPER).

備註:
  1. Call this function before StartWaveIn() to repvent weird behavior.
  2. waveOutWriteStart will be set to false.
  3. waveOutDoneCount will be set to 0.
  4. When two frames are returned from waveIn, waveOutWriteStart will be set to true (in waveInProc(), and waveInProc() will start to write frame to waveOut device.
  5. When a frame is done with waveOutWrite, waveOutDoneCount will be increased by 1.

定義在 waveAPI.cpp 檔案之第 120 行.

參考 AssertWaveError(), channels, format, FRAMESIZE, samplingRate, WAVE_OUT, waveAPIInit(), waveAPIInitialized, waveInBuffers, waveOutDoneCount, waveOutHandle, waveOutHeaders, waveOutProc(), waveOutWriteStart, 及 WIBLSIZE.

void StartWaveIn (  ) 

Call waveInStart() to start recording.

備註:
  1. waveInStatus will be set to 1.
  2. Two buffers will be prepared and added (to prevent frame dropping).
