To use the {} replacement for the file, xargs should have the -i
option:

    ... | xargs -0 -i sox '{}' ...

Of course, the xargs manpage says that -i is deprecacted and you
should instead use -I replace-str.  You can make things more readable
this way as well:

    ... | xargs -0 -I wav sox 'wav' ...
