ABSTRACT:
A sound processing apparatus is provided with a sound information input device, a recording device to record the sound information, a converting device to convert the sound information into image information, and a display device to display the image information, the display device being such that the vertical and horizontal directions of the display device are time axes and the unit of one of the time axes is longer than the unit of the other time axis. The image information displayed on the display device can be selected by a selection device to display the sound information. The sound information can also be displayed as image information corresponding to a frequency component of the sound information within a predetermined time. The frequency component may be detected using discrete cosine transformation (DCT) for compressing the sound information.
