         7 . The method of  claim 1 , wherein the selecting of the part of the oscillation graph comprises defining the part of the oscillation graph by at least one of touching a start point on the oscillation graph and sliding the touch to an end point along a timeline, and touching a start point and an end point on the oscillation graph. 
     
     
         8 . The method of  claim 1 , further comprising playing, when a part of the oscillation graph is selected, audio data of the audio file corresponding to the selected part of the oscillation graph. 
     
     
         9 . The method of  claim 1 , wherein the displaying of the selected part of the oscillation graph within an edit window comprises:
 designating the selected part as a source audio data in response to a touch event; and   displaying a visual effect of moving the source audio data from the oscillation window to the edit window in response to a drag event.   
     
     
         10 . The method of  claim 9 , wherein the displaying of the selected part of the oscillation graph within an edit window further comprises displaying the text information corresponding to the selected part of the oscillation graph within the edit window. 
     
     
         11 . The method of  claim 1 , further comprising:
 storing the selected part of the oscillation graph temporarily;   saving the selected part as a ringtone file; and   setting the ringtone file as a ringtone of the mobile terminal.   
     
     
         12 . An audio file edit apparatus for a mobile terminal, the apparatus comprising:
 a display unit for displaying an audio file edit application screen according to the execution of an audio file edit application;   a storage unit for storing the audio file edit application and audio files;   a touch screen for generating a command for editing the audio files in response to a touch event input by a user; and   a control unit for controlling to display an oscillation graph representing an audio file selected in response to a touch event, for selecting a part of the oscillation graph in response to a touch event, and for displaying the selected part of the oscillation graph in response to a touch event.   
     
     
         13 . The apparatus of  claim 12 , wherein the control unit controls text information corresponding to the oscillation graph. 
     
     
         14 . The apparatus of  claim 13 , wherein the file edit application screen comprises:
 at least one oscillation window for displaying the oscillation graph;   a text window for displaying the text information;   an edit window for displaying the selected part of the oscillation graph;   a menu bar having at least one of a “file” button for selecting the audio file, a “select” button” for selecting the part of the oscillation graph, a “play” button for playing the selected part of the oscillation graph, and a “save” button” for saving audio data corresponding to the selected part of the oscillation graph; and   at least one navigation button for scrolling at least one of the oscillation graph which is displayed in the oscillation window, the text information which is displayed in the text window, and the selected part of the oscillation graph which is displayed within the edit window.   
     
     
         15 . The apparatus of  claim 14 , wherein the edit window further displays the text information corresponding to the selected part of the oscillation graph. 
     
     
         16 .
