Sound processing apparatus

An azimuth angle information extractor for extracting azimuth information of a sound source from at least one pair of stereo acoustic information; A touch screen on which an image is displayed; A reader for reading a touch state of the touch screen; And a synthesizer that characterizes the sound source having the azimuth information corresponding to the touched portion on the image according to the touch state, and synthesizes and outputs the sound source when compared with other sound sources. According to the present invention, various needs of the user can be met by utilizing the azimuth information of the sound source, and it is possible to satisfy not only the sound but also the user's need for the reproduction of the image, It is possible to implement a highly usable image reproducer.
