coupling a terminal with a plurality of audio output devices; and

allocating a plurality of audio sources generated by the terminal to the plurality of audio output devices.

2. The signal processing method of claim 1, further comprising generating and managing information regarding allocation details of the plurality of audio output devices.

3. The signal processing method of claim 1, wherein the allocating comprises allocating different audio sources to different audio output devices.

4. The signal processing method of claim 3, wherein the allocating comprises randomly allocating the plurality of audio sources to the plurality of audio output devices.

5. The signal processing method of claim 3, wherein the allocating comprises allocating an audio source, for which an execution instruction has been provided, to an audio output device having a higher priority.

6. The signal processing method of claim 5, wherein priorities for the plurality of audio output devices are allocated to the plurality of audio output devices based on a coupling order.

7. The signal processing method of claim 5 wherein priorities for the plurality of audio output devices are set by a user.

8. The signal processing method of claim 5, wherein priorities for the plurality of audio output devices are set to default.

9. The signal processing method of claim 1, wherein the allocating comprises:

outputting a device allocation setup User Interface (UI);

selecting an audio source and an audio output device in the device allocation setup UI; and

allocating the selected audio source to the selected audio output device.

10. The signal processing method of claim 9, wherein the device allocation setup UI comprises an icon indicating an audio output device.

11. The signal processing method of claim 10, wherein the selecting of the audio source and the audio output device comprises:

selecting one icon; and

placing the icon on an application window through a drag and drop process for the icon.

12. The signal processing method of claim 11, wherein the allocating of the selected audio source to the selected audio output device comprises allocating an audio source executed in the application window on which the icon is placed to an audio output device indicated by the icon.

13. The signal processing method of claim 10, wherein the selecting of the audio source and the audio output device comprises:

selecting one application window; and

placing the application window on one icon through a drag and drop process for the application window.

14. The signal processing method of claim 13, wherein the allocating of the selected audio source to the selected audio output device comprises allocating an audio source executed in the selected application window to an audio output device indicated by the icon.

15. The signal processing method of claim 9, wherein the device allocation setup UI comprises at least one of a list box and a combo box to display the plurality of audio output devices and the plurality of audio sources.

16. The signal processing method of claim 15, wherein the selecting of the audio source and the audio output device comprises selecting one audio output device and one audio source from the list box or the combo box.

17. A user terminal comprising an audio output processing unit, which is coupled with a plurality of audio output devices and allocates a plurality of audio sources to the plurality of audio output devices.

18. The user terminal of claim 17, wherein the audio output processing unit generates and manages information regarding allocation details of the plurality of audio output devices.

19. The user terminal of claim 17, wherein the audio output processing unit allocates different audio sources to different audio output devices.

20. The user terminal of claim 19, wherein the audio output processing unit randomly allocates the plurality of audio sources to the plurality of audio output devices.

21. The user terminal of claim 19, wherein the audio output processing unit allocates an audio source, for which an execution instruction has been provided, to an audio output device having a higher priority.

22. The user terminal of claim 21, wherein the priorities for the plurality of audio output devices are determined based on a coupling order.

23. The user terminal of claim 21, wherein the priorities for the plurality of audio output devices are set by a user.

24. The user terminal of claim 21, wherein the priorities for the plurality of audio output devices are set to default.

25. The user terminal of claim 17, further comprising:

a display unit to output a device allocation setup User Interface (UI); and

a UI unit to select an audio source and an audio output device in the device allocation setup UI,

wherein the audio output processing unit allocates the selected audio source to the selected audio output device.

26. The user terminal of claim 25, wherein the device allocation setup UI comprises an icon indicating an audio output device.

27. The user terminal of claim 26, wherein the UI unit is configured to select one icon and to place the icon on an application window through a drag and drop process for the icon.

28. The user terminal of claim 27, wherein the audio output processing unit allocates an audio source executed in the application window on which the icon is placed to the audio output device indicated by the icon.

29. The user terminal of claim 26, wherein the UI unit is configured to select one application window and to place the application window on one icon through a drag and drop for the application window.

30. The user terminal of claim 29, wherein the audio output processing unit allocates an audio source executed in the selected application window to the audio output device indicated by the icon.

31. The user terminal of claim 25, wherein the device allocation setup UI comprises one of a list box and a combo box to display the plurality of audio output devices and the plurality of audio sources.

32. The user terminal of claim 31, wherein the UI unit is configured to select one audio output device and one audio source from the list box or the combo box.

33. A computer readable recording medium storing a computer readable program to execute a signal processing method comprising:

coupling with a plurality of audio output devices; and

allocating a plurality of audio sources to the plurality of audio output devices.

34. A user terminal to process an audio signal, comprising:

a plurality of terminals; and
