Formatting Audio Capture

The following example uses capSetAudioFormat19TEZKX to set the audio format to 11-kHz PCM 8-bit, stereo.

WAVEFORMATEX wfex;

wfex.wFormatTag = WAVE_FORMAT_PCM;

wfex.nChannels = 2;                // Use stereo

wfex.nSamplesPerSec = 11025;

wfex.nAvgBytesPerSec = 22050;

wfex.nBlockAlign = 2;

wfex.wBitsPerSample = 8;

wfex.cbSize = 0;

capSetAudioFormat(hWndC, &wfex, sizeof(WAVEFORMATEX));
