X3DAUDIO_DISTANCE_CURVE structure (x3daudio.h)

  • Article

Defines an explicit piecewise curve made up of linear segments, directly defining DSP behavior with respect to normalized distance.

Syntax

typedef struct X3DAUDIO_DISTANCE_CURVE {
  X3DAUDIO_DISTANCE_CURVE_POINT *pPoints;
  UINT32                        PointCount;
} X3DAUDIO_DISTANCE_CURVE, *LPX3DAUDIO_DISTANCE_CURVE;

Members

pPoints

X3DAUDIO_DISTANCE_CURVE_POINT array. The array must have no duplicates and be sorted in ascending order with respect to distance.

PointCount

Number of distance curve points. There must be two or more points since all curves must have at least two endpoints defining values at 0.0f and 1.0f normalized distance, respectively.
