Looks like mplayer generates raw WAVs by default if you do
-ao pcm; see man mplayer(1):

       pcm
	      Raw PCM/wave file writer audio  output.	Writes	the  sound  to
	      ./audiodump.wav.

It didn't, unfortunately. Looks like sox doesn't actually
make concatenation easy. See, e.g.,

http://www.boutell.com/scripts/catwav.html

Presumably the easiest approach is to manually output raw
WAVs using mplayer, cat them together, then use mplayer to
reformat them using whatever your chosen codec is.
