It would be really great, if SoX would be able to encode opus output files (in addition to decoding/reading opus input files, as implemented in recent git).
Opus is the new state of the art free audio codec and IMHO it is important that it becomes as widespread as possible!
BTW, thanks for the great work on SoX!

Done in "main" branch. If you can compile and test that would be great,
