The DSCCAPSstructure is used by the IDirectSoundCapture::GetCapsmethod.
typedef struct {
DWORD

;
DWORD

DWORD

DWORD

} DSCCAPS, *LPDSCCAPS;
typedef const DSCCAPS *LPCDSCCAPS;
Members
- dwSize
- Size of the structure, in bytes. This member must be initialized before the structure is used.
- dwFlags
- Specifies device capabilities. Can be 0 or the following flag:
Flag Description DSCCAPS_EMULDRIVER There is no DirectSoundCapture driver for the device, so the standard wave audio functions are being used. - dwFormats
- Standard formats that are supported. These are equivalent to
the values in the
WAVEINCAPSstructure used in the Win32 waveform audio
functions, and are reproduced here for convenience.
Value Description WAVE_FORMAT_1M08 11.025 kHz, mono, 8-bit WAVE_FORMAT_1M16 11.025 kHz, mono, 16-bit WAVE_FORMAT_1S08 11.025 kHz, stereo, 8-bit WAVE_FORMAT_1S16 11.025 kHz, stereo, 16-bit WAVE_FORMAT_2M08 22.05 kHz, mono, 8-bit WAVE_FORMAT_2M16 22.05 kHz, mono, 16-bit WAVE_FORMAT_2S08 22.05 kHz, stereo, 8-bit WAVE_FORMAT_2S16 22.05 kHz, stereo, 16-bit WAVE_FORMAT_4M08 44.1 kHz, mono, 8-bit WAVE_FORMAT_4M16 44.1 kHz, mono, 16-bit WAVE_FORMAT_4S08 44.1 kHz, stereo, 8-bit WAVE_FORMAT_4S16 44.1 kHz, stereo, 16-bit - dwChannels
- Number specifying the number of channels supported by the
device, where 1 is mono, 2 is stereo, and so on.
