  Hi,
 I'm making a random "beat" generator based on a directory tree of
 samples and a map file.  Currently, it shuffles sample order and
 creates a list of samples and their corresponding start time (example
 list below).
 I need a good way to mix all of these seperate samples into one single
 audio file based on the time at which each starts at.  Any
 recommendations or thoughts would be appreciated.  File format doesn't
 matter, I'll use whatever is easiest.
 Thanks,
 Erik Nomitch

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).
