Parameter
|
Description
|
|
|
nIndexVolumePoint
|
Zero-based index of the volume point
|
fPosition
|
Position, expressed in the unit set through the Effects.VolumeAutomationSetScales method, where the volume point will be applied
|
fVolumeLevel
|
Volume applied starting from the current automation point: the value is expressed in the unit set through the Effects.VolumeAutomationSetScales method.
|
nCurveType
|
Type of curve applied to reach the next volume point.
Supported values are the following:
Mnemonic constant
|
Value
|
Meaning
|
|
|
|
VOLUME_CURVE_NONE
|
0
|
No curve is applied: volume will be changed immediately and will be kept till next volume point.
|
VOLUME_CURVE_LINEAR
|
1
|
Linear curve
|
VOLUME_CURVE_EXPONENTIAL
|
2
|
Exponential curve
|
VOLUME_CURVE_COSINE
|
3
|
Cosine curve
|
VOLUME_CURVE_SMOOTH
|
4
|
Smooth curve
|
VOLUME_CURVE_CUSTOM
|
5
|
Custom Bézier curve.
