Used by the Dieffect structure to specify the optional TermEnvelope parameters for an effect. The TermSustain level for the envelope is represented by the dwMagnitude member of the Diperiodic structure and the lMagnitude member of the Diconstantforce structure. The sustain time is represented by dwDuration member of the Dieffect structure.

Members Table
The following table lists the members exposed by the object. Click a tab on the left to choose the type of member you want to view.
Amplitude for the start of the envelope, relative to the baseline, in the range from 0 through 10,000. If the effect's type-specific data does not specify a baseline, the amplitude is relative to 0.
Amplitude for the end of the envelope, relative to the baseline, in the range from 0 through 10,000. If the effect's type-specific data does not specify a baseline, the amplitude is relative to 0.
