PROBLEM TO BE SOLVED: To provide an audio processing device capable of precisely determining water wetting of the audio processing device and suppressing deterioration in sound quality due to the water wetting.SOLUTION: An audio processing device includes a loudspeaker part having a loudspeaker 19; a reference sound signal generation part 14 which generates a signal for outputting a reference sound from the loudspeaker 19; a reference microphone 11 which picks up the reference sound output from the loudspeaker 19 in a case; a reference characteristic storage part 13 which stores a sound collection signal, obtained by previously picking up the reference sound by the reference microphone 11 while the loudspeaker is not wetted with water, as first reference characteristics; and a water wetting determination part 16 which determines that the loudspeaker part is wetted with water on the basis of the first sound collection signal 21 obtained by picking up the reference sound by the reference microphone 11 and the first reference characteristics 26 stored in the reference characteristic storage part 13. |
