That's a big surprise, I thoguht it's about sending audio and video somehow.

Medium or media does not necessarily refer to an mp3 or a youtube video. See the original meaning of medium.

Of course it doesn't need to be audio nor video. It doesn't change the fact that you used a term that has more than one meaning without providing any context in which to interpret it. If somebody misreads it, then the problem is with your prose, not with the reader.
