I know that ecasound is designed to make it easy to do this sort of
thing. A second option is using your favorite text manipulation
programming language to generate an ardour session file (ardour
session files are human readable/editable XML, I recommend loading and
arranging a few clips in ardour, saving the session, and using the
resulting file as a template if you go that route).
