WAVEFILTER structure

The WAVEFILTER structure defines a filter for waveform-audio data. Only filter information common to all waveform-audio data filters is included in this structure. For filters that require additional information, this structure is included as the first member in another structure along with the additional information.

Syntax


typedef struct {
  DWORD cbStruct;
  DWORD dwFilterTag;
  DWORD fdwFilter;
  DWORD dwReserved[5];
} WAVEFILTER;
