Remarks

Performs an Undo operation restoring previous sound contents.

In order to save system memory, by default Undo operations are disabled: you can enable them through the UndoEnable method and to know if a backup of previous sound contents is available through the UndoIsAvailable method.

A successful call to this method will fire the SoundEditStarted event followed by the SoundEditDone event.
