vue+elementUI使用Wavesurfer.js音频可视化
效果图
安装 wavesurfer.js
npm install wavesurfer.js --save
(datav安装)
npm install @jiaminghi/data-view
在使用界面引用
import WaveSurfer from 'wavesurfer.js' //导入wavesurfer.js
import Timeline from 'wavesurfer.js/dist/plugin/wavesurfer.timeline.js' //导入时间轴插件
在使用界面引用
// 将自动注册所有组件为全局组件
import dataV from '@jiaminghi/data-view'
Vue.use(dataV)
