PURPOSE: A visualizing apparatus of an audio signal is provided to convert stored visualization information according to frequency wavelength of an audio signal and to display converted visualization information. CONSTITUTION: A frequency analyzer(100) analyzes an input audio signal. The frequency analyzer extracts pitch or frequency wavelength of a sound source. An image converter(120) extracts visualization information stored in a memory(110). The image converter converts the extracted visualization information according to the pitch or frequency wavelength of the sound source. A control unit(130) outputs the converted graphic image through a display unit(140). [Reference numerals] (100) Frequency analyzer; (110) Memory; (120) Image converter; (130) Control unit; (140) Display unit; (150) Key signal input unit; (160) Key input unit; (170) Power unit
