//ToDo ... put BlendFrames in Effects, Project, or other class

//ToDo ... Use ZeroCrossing logic to improve blend
|
|
//ToDo ... BlendFrames on "fade-out"
|
|
//ToDo ... BlendFrameCount is a user-selectable parameter
|
|
//ToDo ... Detect transient signals that are too short to interrupt the TruncatableSilence
