Almost the opposite case is Missy's vortex manipulator in Planet of Dust. It is heard near the end, and identified in the following story — but Helen (might have been Liv) only hears it, and does not see Missy or the object. We're given the sound effect, confirmation that a character hears this sound diegetically, but no "visual" confirmation (through techniques like dialogue or narration).

If this were a TV story, there would be no argument, I think: the vortex manipulator does not appear. But in the case of full-cast audio stories, is it more important that we hear the person/object represented in audio (where listeners experience the thing first-hand), or that characters within the story see it (where we can be fairly certain the thing would more traditionally appear in another medium, such as TV or prose)?
