also i hab das jetzt mal so gebastelt:
| C++: |
int _tmain(int argc, _TCHAR* argv[])
{
const int NUMPTS = 44100 * 5; // 5 Sekunden
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;
// Specify recording parameters
WAVEFORMATEX pFormat;
pFormat.wFormatTag=WAVE_FORMAT_PCM; // simple, uncompressed format
pFormat.nChannels=2; // 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
waveInAddBuffer(hWaveIn, &WaveInHdr, sizeof(WAVEHDR));
printf("Sinus_1KHz.wav\n");
GetWaveVolumePercent(true);
SetWaveVolumePercent(25.0,true);
GetWaveVolumePercent(false);
SetWaveVolumePercent(25.0,false);
printf("Aufnahme\n");
PlaySound(TEXT("sinus_1KHz.wav"), NULL, SND_FILENAME);
waveInStart(hWaveIn);
// Warten bis Aufnahme fertig
do {} while (waveInUnprepareHeader(hWaveIn, &WaveInHdr, sizeof(WAVEHDR))==WAVERR_STILLPLAYING);
waveInClose(hWaveIn);
printf("Aufnahme fertig\n");
return 0;
}

das dürfte ja soweit funktionieren, aber wo stehen jetzt die Daten meiner Aufnahme? In einer bestimmten struct oder wie funktioniert das genau??? |
