Method and system for converting audio frequency signals into vision color information

Abstract

The invention provides a method and system for converting audio frequency signals into vision color information. The method includes the steps that first, the audio frequency signals are sampled; second, the brightness V of the audio frequency signals is calculated; third, the hue H and the saturability S of the audio frequency signals are calculated; fourth, the brightness V, the hue H and the saturability S are subjected to RGB color format conversion; fifth, RGB values obtained in the fourth step are subjected to color mixing, and finally, the color values of the audio frequency signals are extracted. According to the method and system, the acquired audio frequency signals are quantitatively processed, the energy values of the audio frequency signals are calculated to represent the brightness, the hue and the saturability represented by the audio frequency signals are calculated through FFT processing, then, the obtained brightness, the obtained hue and the obtained saturability are converted into RGB color formats, the whole method performs calculation and deduction according to a scientific principle, the process is a quantitative processing process, expression of object meaning of people is avoided, and the method and system are scientific and precise.

Description

technical field [0001] The present invention relates to the field of audio signal processing, and more specifically, to a method and system for converting audio signals into visual color information. Background technique [0002] Music and fine arts are both important parts of the arts. Just as painting requires a variety of colors, music has a variety of timbres. People have linked the timbre and color of music a long time ago, such as Kircher, a German in the 17th century, who once proposed that music is the imitation of light, and the two can be expressed mutually. Later, this theory was confirmed by the French Castel, who published the book "Music and Color" in 1720, and designed a "Visual Hapsecord" in 1734. The positions are arranged and allocated, a key is connected to a color, and the music score is played by the key, and the light is transmitted from the transparent color band. Later, many scientists, artists, and even writers linked music and color. In 1876, the...

Problems solved by technology

For example, the frequency range of the sound that can be heard by the human ear is related to the frequency range of visible light. The most typical is that seven colors are separated from white light and correspond to seven fundamental scales. This mapping relationship is reasonable. It roughly conforms to the corresponding relationship between timbre and color, but this mapping relationship is limited and not rigorous enough
