I guess this is a bug in sox then. If I use sndfile-concat (by first
turning the first wave file into w64), a correct w64 is made, and if I use
sndfile-salvage on the wave sox produced (the one with too much sound for
the header to explain) a correct file is also made. Either way, success!

Thanks for the insight guys.
