WAVEINCAPS structure

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

Syntax

typedef struct {
  WORD      wMid;
  WORD      wPid;
  MMVERSION vDriverVersion;
  TCHAR     szPname[MAXPNAMELEN];
  DWORD     dwFormats;
  WORD      wChannels;
  WORD      wReserved1;
} WAVEINCAPS;

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
    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_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
    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.

  • wReserved1
    Padding.
