Embodiment 1

[0056] This embodiment discloses an audio visualization method, which specifically includes the following steps:

[0057] Step 1: Acquire audio data, and sort the audio data by frequency to obtain a data group D; wherein, the audio data is subjected to Fourier transform to obtain freq data, which is a floating-point numerical array, and the freq data Sort by frequency from low to high to get data group D; this is the data source, and the visualization image changes according to this data;

[0058] Step 2: Define floating-point numeric sub-arrays M1, M2, ..., Mn, a total of n sub-arrays, each sub-array has a length of m, where the length of the first n*m items is less than or equal to the length of the data group D; The data group D is the freq data obtained by the Fourier transform of the audio data, and has a large number of sub-arrays. Since this embodiment mainly considers the audio visualization based on the frequency of the audio, when the frequency of the audio is too h...

Embodiment 2

[0074] The present invention also discloses an audio visualization terminal, comprising a memory, a processor and a computer program stored on the memory and running on the processor, and the processor implements the audio when executing the computer program Visualize the individual steps in the method.

Abstract

The invention discloses an audio visualization method and terminal, comprising the following steps: S1: acquire audio data in real time, and sort the audio data by frequency to obtain a data group D; S2: split the first n*m items of the data group D into n equal-length subarrays M1, M2, ..., Mn, each subarray M i Include m data; S3: Calculate each subarray M i The weighted average A of the terms and each sub-array M i The largest value in the subarray is at the position w of the subarray; S4: Input A, w, m of each subarray into the data processing model, obtain the starting point, control point and end point of the Bezier curve of each subarray and draw it, Form the Bezier curve of the sub-array; S5: connect the Bezier curves of all the sub-arrays to form an audio visual image; the invention can display the corresponding pattern by acquiring audio data, so as to realize that when the audio is played, the image can follow The audio changes and changes, while listening to the music, it gives the corresponding visual effects.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to an audio visualization method and a terminal. Background technique [0002] With the development of society, there are more and more types of audio devices on the market and more and more functions. Many audio devices are provided with multiple audio input interfaces and multiple audio output interfaces. Some existing music softwares have visualization functions, such as transformation of shapes, graphics, colors, etc. However, the audio data processing process of the existing audio visualization method is cumbersome, the processing time is long, and the display effect is poor, and it cannot quickly and effectively reflect the volume level of the audio and the changing frequency of the audio at the same time, which reduces people's vision. experience. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an audio visualization method a...
