Remarks
Adds a new volume point to the current volume automation procedure.
For further details about defining a volume automation procedure refer to the How to define a volume automation procedure section.

Parameter
|
Description
|
|
|
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.
|
|
nDesignerUniqueId
|
Unique identifier of the curve editor control containing custom curve settings to apply. This unique identifier is returned by a previous call to the Effects.CurveDesigner.Create method.
The custom curve designer manages a windowed control, whose visual aspect can be defined programmatically, which allows designing volume curves based upon Bézier curves whose shape is defined through the manual positioning of 2 control points (displayed in cyan color on the graphic below). For further information about the use of the embedded CurveDesigner refer to the tutorial How to create custom volume curves.

Return value
Value
|
Meaning
|
|
|
Negative value
|
An error occurred (see the LastError property for further error details)
|
enumErrorCodes.ERR_NOERROR (0)
|
The method call was successful.
