Abstract: 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.

Conversion of acoustic signals into visual signals
Esser Guenter Prof Dr
- 29 Mar 1983
TL;DR: For displaying spoken words as color pictures on a screen, each audio frequency, i.e., each acoustic sound, is assigned a respective color hue and each audio spectrum spectrum a corresponding color mixture, by conducting acoustic signals through a three-channel triangular filter, each channel having a different central frequency, and controlling the intensity of a respective electron beam of a color television monitor as a function of each filter channel output.

- 19 May 1987
TL;DR: In this paper, an apparatus for displaying two-channel audio input signals in a three-color visual pattern is described, where phase shifting means is employed to phase shift one of the two audio input signal components, and both audio signals are subsequently processed by low pass filters to produce positioning signals in X-Y coordinates for the spot which forms the visual pattern.
