capWaveStreamCallback

The capWaveStreamCallback function is the callback function used with streaming capture to optionally process buffers of audio data. The capWaveStreamCallback callback function is a placeholder for the application-supplied function name.

LRESULT CALLBACK capWaveStreamCallback(
  HWND hWnd,        
  LPWAVEHDR lpWHdr  
);
 

Parameters

hWnd

Handle of the capture window associated with the callback function.

lpWHdr

Address of a WAVEHDR structure containing information about the captured audio data.

Remarks

The capture window calls a wavestream callback function when an audio buffer is marked done by the waveform-audio driver. When capturing to disk, this will preceed the disk write operation.
