For a general description of using Drag and Drop in Reaper please see: Main rules for drag and drop audio files.


For Reaper in particular, you will need to press the keys <CMD><ALT> in macOS  (<CTRL><ALT> in Windows) before dragging audio from Reaper to Revoice Pro.


Once you have dragged and dropped audio regions from Revoice Pro to Reaper, you can use Reaper's command "Move Items to Source Preferred Position" to spot the audio region to its original timecode. You access this command in the Item->Item Processing sub-menu.
