Part of the picture is how the signal is propagated.  If a 10 KHz signal is
sent to a speaker and propagated through the air, then it's audio.  You
could also couple it to an antenna and tickle the ether - then you would be
considered to be sending RF energy.

If you send it through wires to another piece of electronic gear, then I
guess it's neither RF or AF - just oscillations at a particular frequency
traveling down the wire or cable.
