Tone visualizing apparatus

A tone visualizing apparatus for visualizing an inputted audio signal to thereby display an image corresponding to this audio signal includes at least a detector, image display (such as a CRT display unit) and display controller. The detector detects characteristics of the audio signal such as envelope, chord, spectrum signal components, number of zero-cross points and energy of the audio signal. The image display displays an image based on given image information which can be generated from a video tape recorder (VTR), a video disk unit or an image memory constituted by a semiconductor memory. The display controller controls the image display so that a display parameter of the image will be controlled based on the detected characteristics of the audio signal. For example, the display parameter can be set as size, brightness or colors of the image. Thus, the image is controlled so that the impression of the image will be matched with that of the audio tone.
