WAVEINCAPS structure (mmeapi.h)

  • Article

The WAVEINCAPS structure describes the capabilities of a waveform-audio input device.

Syntax

typedef struct waveincaps_tag {
  WORD    wMid;
  WORD    wPid;
  VERSION vDriverVersion;
  char    szPname[MAXPNAMELEN];
  DWORD   dwFormats;
  WORD    wChannels;
} WAVEINCAPS, *PWAVEINCAPS, *NPWAVEINCAPS, *LPWAVEINCAPS;

Members

wMid

Manufacturer identifier for the device driver for the waveform-audio input device. Manufacturer identifiers are defined in Manufacturer and Product Identifiers.

wPid

Product identifier for the waveform-audio input device. Product identifiers are defined in Manufacturer and Product Identifiers.

vDriverVersion

Version number of the device driver for the waveform-audio input device. The high-order byte is the major version number, and the low-order byte is the minor version number.

szPname[MAXPNAMELEN]

Product name in a null-terminated string.

dwFormats

Standard formats that are supported. Can be a combination of the following:

Format 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_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
WAVE_FORMAT_96M08 96 kHz, mono, 8-bit
WAVE_FORMAT_96M16 96 kHz, mono, 16-bit
WAVE_FORMAT_96S08 96 kHz, stereo, 8-bit
WAVE_FORMAT_96S16 96 kHz, stereo, 16-bit

wChannels

Number specifying whether the device supports mono (1) or stereo (2) input.
