Accordingly, the communication terminal 100 receives the touch operation corresponding to the setting instruction of the touch input area in the state (a), and generates and displays the touch input area 641 (b).

6C, the communication terminal 100 displays a menu area 651 for setting a control mode according to a user's selection while displaying output values of frequency bands of predetermined audio data, (A).

The communication terminal displays the control mode list 661 in one area of the screen 660 as the menu area 651 is activated (b).

When the user setting 661-1 is selected from the control mode list 661, the communication terminal 100 generates a touch input area 671 for receiving a drag operation and displays the touch input area 671 in one area of the screen c).

Hereinafter, with reference to FIG. 7, a process of setting a plurality of control values corresponding to the touch pattern for the touch input area set in FIGS. 6A to 6C will be described in terms of the screen configuration. 7 is a screen configuration diagram illustrating a process of setting a plurality of control values corresponding to a touch pattern of a drag operation input on a touch input area.

The communication terminal 100 simultaneously displays the touch input area 711 in one area of the screen 710 while displaying the output value of each predetermined frequency band of the audio data (a).

The user drags (b) onto the pointer 723 on the touch input area 721 to form a curve 722 from one point 722-1 to another point 722-2.

The communication terminal 100 recognizes a region where a point matching with the curve 722 formed in the state (b) of the plurality of regions 511-1 to 511-7 exists, (512-1 to 511-7) of the recognized areas (511-1 to 511-7) so as to change the output value of each frequency band of the audio data to a size corresponding to the matching point, 512-7) (c).

Alternatively, the user drags (d) onto the pointer 743 such that an identifier "C" 742 for identifying the control mode corresponding to the classic is formed on the touch input area 741. [

The communication terminal 100 changes the predetermined frequency-dependent output value to a frequency-specific output value that is most suitable for the class, and outputs the changed frequency-dependent output value to the plurality of areas 511-1 to 511- (E) at least one of the indicators (at least one of 512-1 through 512-7).

Hereinafter, a graph illustrating a plurality of control values set corresponding to a touch pattern according to an embodiment of the present invention will be described with reference to FIG. 8 is a graph showing a plurality of control values set corresponding to the touch pattern of the drag operation.

8, a case where a drag operation for changing the output value for each frequency is input on the touch input area 811 will be described, as shown in (a).

(b), the communication terminal 100 first sets the reference frequency at the time of inputting the drag operation. The output value of the reference frequency is set to 0 dB. Therefore, at a frequency other than the reference frequency, the output value setting / changing operation can be performed while the output value of the reference frequency is fixed to 0 dB. Of course, the output values of the reference frequency and the reference frequency can be changed by the user.

First, the communication terminal 100 recognizes the X coordinates (X1, X2) of the starting point and the end point of the curve 812 input through the touch input area 811 and calculates the X coordinate X3 of the center point from the X and Y coordinates To the reference frequency. Generally, X3 corresponds to the sum of X1 and X2 divided by two. Here, the X coordinate represents the frequency (for example, Hz) and the Y coordinate represents the output value (for example, dB).

The communication terminal 100 recognizes the Y coordinates (Y1, Y2) of each of X1 and X2 and determines the inclination of the curve between the respective frequencies by considering that 0 dB is assigned to the Y coordinate (Y3) of X3. For example, if the slope between the reference frequency 1 kHz and 500 Hz is -1, -2 dB is allocated to 500 kHz, and if the slope between 500 kHz and 250 kHz is 1, 2 dB can be allocated.

Therefore, the communication terminal 100 can calculate the output value for each frequency using the slope between the respective frequencies.
