In its broadest sense, "audio" simply means the range of sound frequencies that can be perceived by humans. In that sense, no one invented it, it is simply the stimulus that we receive through the sense of hearing.
If, by "audio", you mean the means to transform sound into an electrical signal, the answer would be about 1876. Both Elisha Gray and Alexander Graham Bell purposefully experimented with devices that functioned as microphones. About two years later, Thomas Edison developed the phonograph, an audio recording and playback device, but it was purely a mechanical device and did not use electrical signals.
