小程序录音与播放录音趟坑

发布时间：6年前热度： 9436 ℃评论数：

测试环境 iphoneX 12.4

测试环境 小米 android 9

通过上边两张图可以看出差异 ：

 IOS中  在点击暂停录音之后，点击继续录音，调用继续录音事件，  会先执行一次继续录音事件再执行开始录音事件

而在android中， 在点击暂停录音之后，点击继续录音，调用继续录音事件，  会先执行一次继续录音事件再执行继续录音事件

在此处涉及到录音计时，平台差异导致定时器一直处于异常，调节时间超出开发预期，做以记录。


在语音播放上，编辑器不会触发语音播放完成事件，android与IOS真机器正常
