Crap, it doesn't seem to do the job. ANy more ideas?
After settling on a rate of 10240 which seems to give me the
correct pitch, I batch-converted the files like so, in the
sounds/ directory:

mkdir fixed
find . -maxdepth 1 -name "*wav" -exec sox -r 10240 {} -r 44100 fixed/{} \;
mkdir orig
mv *wav orig
mv fixed/*wav .

This seemed to go OK, except that sox complains for each file:
sox: wave header missing FmtExt chunk

(... which means what exactly?)

Anyway, the resulting files play just fine via sox, but ardour
doesn't like them - they load without complaint but they sound like
white noise.

Note also that sndfile-info seems to report mostly similar information 
to the originals, and I'm not clear on what the differences mean:
