H5实现移动端语音录制功能

前言：

年前做了一期语音口令的年度活动，从语音录制、上传到智能检测，以及后续的语音播放组件，语音录制的实现的方式是基于微信的JSSDK，本篇主要把语音录制板块整理了一下，供大家参考；

下一篇-音频组件

各位看官先上眼：

功能梳理：

视图层

• 定义动态效果状态标识

  区分几种录制状态
  isAudioState: 0 // 0 未录制or检测完毕 1 录制中 2 检测中
  ：未录制or检测完毕     / 0 无动效
  ：录制中               / 1 波浪纹
  ：检测中               / 2 环形检测
  

• 设置动态效果切换状态

  通过监听touchstart/touchend事件去切换动态效果
  

逻辑层

 录制、上传、检测功能
 时间限制（时间区间）、内容为空的兼容处理

• touchstart事件中做了哪些事

  1.开启录音
  2.切换录音中状态
  3.开始计时，用于记录音频时长
  

• touchend事件中做了哪些事

  1.停止录音
  2.智能检测
  3.控制录音时长
  4.上传音频
  5.切换录音结束状态（是否开始检测）
  

USE API（JS-SDK）

 开始录制 startRecord
 停止录制 stopRecord
 智能检测 translateVoice （将语音转文字）
 上传音频 uploadVoice （将录制的临时音频文件上传至微信服务，供服务）

这里就不赘述了，可以去猫一眼微信的官方文档 点击前往

代码层：

 注：所有逻辑均在此组件，父级组件引入即可

注意事项：

• 上述逻辑中均为同步操作，以应对服务端异步获取当次录音的音频文件（目的在于需确报本次音频上传成功后再与服务端交互）；

• 微信音频格式为speex，需转格；

• 部分浏览器存在touch img呈现预览模式的解决方案，img{ pointer-events: none; }；

• audioStart时，部分浏览器存在用户同时触发下拉动作后松手无法touchend的情况，需preventDefault操作;

• 米8在触发上传、检测api时，会造成检测动画的卡顿，（其他机型没问题），初步怀疑是线程阻塞，有兴趣的可以一块研究一下~(方案：动画轨迹被阻塞/dom渲染被打断（gif），所以回调后，可以使用时间戳的方式重新绘制图片；其他类似场景也可以使用这种方案，当然针对性场景，具体情况还要重新定义~)

服务端针对微信speek格式音频优化

针对微信的speex高清音频格式，服务端的小可爱做了以下处理； 处理音频为前端可识别格式wav，并转格为mp3，并再次压缩；友好前端格式、提高的效率的同时又极大的节约了成本；有兴趣的同学可以去看一下， 作者：purewater2014，微信高清音频处理链接。

结语：

本篇简要概述了H5语音的录制模块，下一篇说一下本次活动中，类微信语音列表的render方式组件的实现；感谢，不当之处欢迎指正交流~
