Embodiment Construction

[0050] The audio visualization implementation method provided by the embodiment of the present invention. The principle is as figure 2 As shown, by extracting the attribute information of the audio signal contained in the audio file (including at least the corresponding tempo information, and also including the energy information of the audio signal), determine the change parameters of the picture elements in the selected picture generation model, and generate the above-mentioned The video model corresponding to the audio file generates a video file corresponding to the audio file according to the generated video model, and plays the generated video file synchronously when the audio file is played.

[0051] The audio visualization implementation method provided by the embodiment of the present invention, its process is as follows image 3 As shown, the specific execution steps are as follows:

[0052] Step S101: extracting audio signal attribute information corresponding to...

Abstract

The invention discloses a method for implementing audio visualization, which comprises the steps of: extracting audio signal attribute information in an audio file, wherein the attribute information at least comprises beat information of the audio signal; determining change parameters of picture elements in a selected picture generation model according to the attribute information and generating a video model corresponding to the audio file; and generating a video file corresponding to the audio file according to the video model. The video file generated with the method can reflect the beat information of the audio file better and obtain better video visualization effect.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to a method and device for realizing audio visualization based on a parameter model. Background technique [0002] Audio visualization has been widely used in handheld multimedia devices and PC players. For example: Windows Media Player, Winamp and other commonly used audio playback software can support the audio visualization function. Audio visualization refers to not only displaying song lyrics or other audio information when playing pure audio or music, but also displaying rich graphical information, such as: displaying spectral contours, transformed geometric figures, or music-related beating figures, etc. Wait. These displays are generally referred to as visualizations. [0003] Currently, the implementation of audio visualization functions is based on the parameter mode. Specifically, the realization of the existing audio visualization effects is based on the change of au...
