DSCCAPS

The DSCCAPS structure is used by the IDirectSoundCapture::GetCaps method.

typedef struct {
    DWORD  dwSize;
    DWORD  dwFlags;
    DWORD  dwFormats;
    DWORD  dwChannels;
} 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 flags:

DSCCAPS_EMULDRIVER

There is no DirectSoundCapture driver for the device, so the standard wave audio functions are being used.

DSCCAPS_CERTIFIED

The driver for the device is a certified WDM driver.

dwFormats

Standard formats that are supported. These are equivalent to the values in the WAVEINCAPS structure used in the Win32 waveform audio functions, and are reproduced here for convenience.

Value	Meaning
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.
