Terminal, the diagnostic system and program

A as compared with the case of frequency without specifying where to get the sound information analysis, to facilitate the identification of causes of abnormal noise. A sound acquiring unit 31 acquires the sound information by entering the abnormal noise generated in the image forming apparatus 20 is a device to be analyzed. Reception unit 38 receives a recording position information for acquiring sound information by the user. The frequency analyzing unit 32 performs a STFT (Short Time Fourier Transform) of the sound information acquired by the sound acquisition unit 31 generates a frequency spectrum waveform data. Control unit 33, and the frequency spectrum waveform generated, similar to the frequency spectrum waveform generated from a plurality of frequencies spectacle waveform of the server device 50, a spectrum waveform which is selected based on the received recording position information It received. .Field
