Abstract

The invention discloses a method for drawing a real-time music frequency spectrum vector graph. The method specifically comprises the following steps of parameter initialization, audio analysis, audio data calling, data conversion and graph processing. In order to improve the rhythm feeling and the interaction feeling of the music frequency spectrum, the real-time high-precision analysis of the frequency spectrum is realized; the diversity of frequency spectrum graph types and the diversity of graph parameter changes are realized; real-time performance of frequency spectrum drawing is realized, and graphic image quality is improved.

Description

technical field

[0001] The invention relates to the field of audio and video processing, more specifically, it relates to a method for drawing real-time music spectrum vector graphics. Background technique

[0002] Music has always been an art form to express emotions, but listening to music in the traditional sense can no longer satisfy people's pursuit of a colorful world, so music visualization came into being. It also coincided with the considerable development of computer technology in image processing, virtual reality, digital signal processing, etc., which laid the foundation for the further development of music visualization technology. The visual display of the music spectrum is an important part of it, but the existing music spectrum drawing effect is monotonous, basically based on the changes in the histogram; and the visual effect lacks the sense of auditory and visual interaction, and the visual sense of rhythm is not good enough. Strong, poor overall experienc...
