There isn't one. Putting Opus into RIFF is complicated by the fact that
it requires both variable-duration and variable-size frames, though I
suppose something could be done along the lines that FFmpeg used for
Vorbis (though how you would handle issues like pre-skip, end trimming,
and pre-roll, I have no idea).
Why do you ask?
