In this case, the total play time is displayed in units of hours, minutes, and seconds 440 based on the calculated result of the bar 430 that visually represents the total play time of the corresponding audio file. The amount of change as the audio file is played back, that is, the current time point at which the audio file is played, is displayed on the bar 450 in a predetermined color. Accordingly, the user can visually easily know the total playback time of the audio file to be played and the current time point to be played. The total playing time can be calculated based on the storage capacity of the corresponding audio file and the playing speed according to the file type. Specifically, when the audio file is an MP3 file, it has a processing speed of approximately 0.0152 Mbytes / sec. Thus, the total playback time of a 4 mega MP3 file can be calculated as about 4 minutes 20 seconds.

Meanwhile, after the selected audio file is displayed, the controller 100 determines whether there is a section setting request by the user in step S230. That is, it is determined by the user whether there is a request for switching to a specific key or section setting mode for section setting, and if the request is a result of the user, the process proceeds to step S240.

The controller 100 displays the section setting screen for setting the section of the audio file selected in step S340 through the display 110. The section setting screen is also the same as the first embodiment of the present invention. If a start time point and an end time point are input, the control unit 100 proceeds to step S350 to recognize the input start time point or the end time point and sets a section between the two time points as a section desired by the user. As in the first embodiment of the present invention, the start time point and the end time point can be input in units of hours, minutes, and seconds, and the section setting process when only the start time point or the end time point is input is also the same. When the section setting is completed, the controller 100 may display a section setting message through the display unit 110.

After displaying the section setting message, the controller 100 proceeds to step S360 to determine whether there are a plurality of audio files selected by the user. That is, it is determined whether there is a second audio file. If there is a second audio file selected by the user, the control unit 100 proceeds to step S340 and repeats steps S340 and S350 described above. That is, a start point and an end point of the second audio file selected by the user are input to set a section desired by the user. In this case, when the setting is completed, the controller 100 may display each section set in the plurality of audio files selected by the user on the display unit 110 in a list form. As a result of determination, if there is no second audio file by the user, the section setting is completed and the control unit 100 proceeds to step S370 to complete the section setting and generates the set section of the audio file as a new audio file in the memory 130. ).
