vue解決音頻可視化播放，使用wavesurfer.js
上效果：
1.安裝wavesurfer
?npm install wavesurfer.js
2.在頁面導(dǎo)入
import WaveSurfer from 'wavesurfer.js'
注:我沒有使用時(shí)間軸万牺，所以沒有引入叭披，如果需要再引入
import Timeline from 'wavesurfer.js/dist/plugin/wavesurfer.timeline.js'
3.上源碼

4.注釋：
這個(gè)插件實(shí)在太吊了，官方文檔太厲害汛闸，上鏈接：https://wavesurfer-js.org/
我用到了幾個(gè)方法：
4.1.this.wavesurfer.play(0, 212); 指定開始時(shí)間和結(jié)束時(shí)間蝙茶，以秒為單位，0秒開始诸老，212秒結(jié)束
4.2.this.wavesurfer.on("pause", () => {
? ? ? ? ? ? ? console.log('我暫停了')
? ? ? ? ? ? });
監(jiān)聽暫停
4.3.this.wavesurfer.load(require("../mp3/living.mp3")); 讀取目錄路徑里面的Mp3文件隆夯，可以測(cè)試用
this.wavesurfer.load('xxx.mp3')); 讀取網(wǎng)絡(luò)地址，有接口就用這個(gè)
