Fresher distributions with sox 14.4.2 and above fails with "-2" option. This replaces it with "-b 16", which works. See here: https://sourceforge.net/p/sox/code/ci/45b161d73ec087a8e003747b1aed07cd33589bca/tree/ChangeLog Did not test on distributions older than ubuntu...

There's a missing closing ``` in factory.rs docs. Silly little thing, but bothered me enough to do this.
