Hello,

Years ago i tried to make some voip program... it worked a bit.

If you wanna try such a thing , then its maybe intresting to look
at the code below(C++)

2 programs :

v.exe (capture sample) in rec.data file
vplay.exe opens rec.data and plays the sample.

code(C++) v.exe :


#include "stdafx.h"

#include "windows.h"



#include <stdio.h>

#include <vfw.h>

#include <conio.h>

#include <process.h>

#include <winsock.h>

#include <mmsystem.h>



int main(int argc, char* vari1)

{



#define  TV_VAR      0x1000



BYTE b9[TV_VAR];





MMRESULT m;

GSM610WAVEFORMAT g;

WAVEHDR *w;

WAVEHDR *w2;



WAVEFORMATEX wf;

HWAVEIN   hw={0};

HWAVEOUT hout={0};

HMIXER hm;

WAVEINCAPS    caps;

WAVEOUTCAPS    caps2;

UINT  ui;

int r;





wf.nSamplesPerSec=8000;

wf.wBitsPerSample=8;

wf.nChannels=1;

wf.wFormatTag=WAVE_FORMAT_PCM;

wf.nBlockAlign=wf.nChannels*(wf.wBitsPerSample/8);

wf.nAvgBytesPerSec= wf.nSamplesPerSec * wf.nBlockAlign;

wf.cbSize=0;













m=waveInOpen(&hw,WAVE_MAPPER,&wf,(DWORD)NULL,(DWORD)NULL,NULL);



m=waveOutOpen(&hout,WAVE_MAPPER,&wf,(DWORD)NULL,(DWORD)NULL,NULL);





w=(WAVEHDR*)HeapAlloc(GetProcessHeap(),HEAP_ZERO_MEMORY,sizeof(WAVEHDR));

w->lpData=(char*)HeapAlloc(GetProcessHeap(),HEAP_ZERO_MEMORY,TV_VAR);

w->lpData=(char*)(b9);

w->dwBufferLength=TV_VAR;

w->dwFlags = 0;



r=waveInPrepareHeader(hw,w,sizeof(WAVEHDR));



r=waveInAddBuffer(hw,w,sizeof(WAVEHDR));



r=waveInStart(hw);



Sleep(20);

r=waveInStop(hw);



strcpy(vari1,(char*)(b9));





FILE * fd;

 fd = fopen ("rec.data","w");

 if (fd!=NULL)

 {

   fputs (vari1,fd);

   fclose (fd);

 }



return *vari1;







// return 0;

}
