声纹可视化工具：wavesurfer.js---在Vue中使用音频声纹可视化插件wavesurfer.js【已封装成组件有完整demo实例附完整代码】

效果图：

完整代码在最后。

使用方法：

1、第一步：使用以下命令安装wavesurfer.js插件库

npm install wavesurfer.js --save

2、第二步：在需要使用的页面import导入wavesurfer.js和其中的时间轴timeline插件

import WaveSurfer from 'wavesurfer.js'
import CursorPlugin from 'wavesurfer.js/dist/plugin/wavesurfer.cursor.js'
import Timeline from 'wavesurfer.js/dist/plugin/wavesurfer.timeline.js'

3、第三步：在<template>里面加入3个主要部分：声纹图案+语音刻度+控制按钮

4、第四步：在<script>里面加入3个主要部分：在data里面预设一些初始值+在mounted里面绘图并监听页面宽度变化后重新加载绘图+在methods里面写入需要使用到的公用方法
