I have never tried to do this, but according to the Audacity man page:
"Audacity is primarily an interactive, graphical editor, not a
batch-processing tool. Whilst there is a basic batch processing tool
it is experimental and incomplete. If you need to batch-process audio or
do simple edits from the command line, using sox or ecasound driven
by a bash script will be much more powerful than audacity."
It seems that sox will do what you want, according to
