Now I have found this sourcecode. I Put it all in a funktion of a Button
(OnButton1), but if I try it it an press the Button , my IPaq crash and I
must reset it. Whats wrong? And how can I save the recorded Data? Here is
the sourcecode:
const int NUMPTS = 44100 * 10; // 10 seconds
int sampleRate = 44100;
short int waveIn[NUMPTS]; // 'short int' is a 16-bit type; I request
16-bit samples below
// for 8-bit capture, you'd use 'unsigned char'
or 'BYTE' 8-bit types
HWAVEIN hWaveIn;
WAVEHDR WaveInHdr;
MMRESULT result;
// Specify recording parameters
WAVEFORMATEX pFormat;
pFormat.wFormatTag=WAVE_FORMAT_PCM; // simple, uncompressed format
pFormat.nChannels=1; // 1=mono, 2=stereo
pFormat.nSamplesPerSec=sampleRate; // 44100
pFormat.nAvgBytesPerSec=sampleRate*2; // = nSamplesPerSec * n.Channels *
wBitsPerSample/8
pFormat.nBlockAlign=2; // = n.Channels * wBitsPerSample/8
pFormat.wBitsPerSample=16; // 16 for high quality, 8 for
telephone-grade
pFormat.cbSize=0;
waveInOpen(&hWaveIn, WAVE_MAPPER,&pFormat,
0L, 0L, WAVE_FORMAT_DIRECT);
// Set up and prepare header for input
WaveInHdr.lpData = (LPSTR)waveIn;
WaveInHdr.dwBufferLength = NUMPTS*2;
WaveInHdr.dwBytesRecorded=0;
WaveInHdr.dwUser = 0L;
WaveInHdr.dwFlags = 0L;
WaveInHdr.dwLoops = 0L;
waveInPrepareHeader(hWaveIn, &WaveInHdr, sizeof(WAVEHDR));
// Insert a wave input buffer
result = waveInAddBuffer(hWaveIn, &WaveInHdr, sizeof(WAVEHDR));
if (result)
{
MessageBox(_T("Failed to read block from device"),
NULL, MB_OK | MB_ICONEXCLAMATION);
return;
}
// Commence sampling input
result = waveInStart(hWaveIn);
if (result)
{
MessageBox(_T("Failed to start recording"),
NULL, MB_OK | MB_ICONEXCLAMATION);
return;
}
// Wait until finished recording
do {} while (waveInUnprepareHeader(hWaveIn, &WaveInHdr,
sizeof(WAVEHDR))==WAVERR_STILLPLAYING);
waveInClose(hWaveIn);
