Embodiment Construction

[0060] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0061] refer to figure 1 , which shows a flow chart of an embodiment of a method for generating animation according to audio music in the present invention, including:

[0062] Step 101, analyzing the preset frequency segment of audio music to obtain rhythm audio and accompaniment audio;

[0063] Audio music contains different frequency components, removing a specific range of frequencies or reducing the amplitude of a specific range of frequencies can achieve a filtering effect, that is, only analyze certain specific frequency bands, filter audio of other frequencies, and obtain audio information of specific musical elements .

[0064] Rhythm information in music is expressed by percussion instruments, and the sound of percussi...

Abstract

The invention provides a method and a system for generating animation according to audio music. The method comprises the following steps of: analyzing the preset frequency band of the audio music to acquire rhythm audio and accompaniment audio; acquiring each audio track according to the frequency characteristic of each audio, and combining to generate an MIDI file; analyzing the music structure of the MIDI file to acquire a music analysis result and the time attribute of the music; establishing each animation element and the corresponding relationship thereof through the preset rule or parameters input by a user according to the preset animation material library and the music analysis result; and combining each animation element and the corresponding relationship thereof into the animation according to the time attribute. The method and the system can automatically generate visual information which has rich contents and corresponds to the contents expressed by the music according to the audio music.

Description

technical field [0001] The invention relates to the technical field of music data processing, in particular to a method and system for generating animation according to audio music. Background technique [0002] With the improvement of living standards, people's appreciation of music has gradually entered into daily life and has become an important way of leisure and entertainment. Usually, people play music only to satisfy the enjoyment of hearing, but to feel the information expressed by music with eyes needs to be developed and researched by people. [0003] A common method is to make the different structural elements that make up the music correspond to different colors, convert the change of music into the change of color, and reflect the change of color type and color depth according to the music attributes represented by different colors. Express the content of the music, such as cheerful or melancholy, soothing or intense. There is also a method that combines music...
