最近接到这样一个需求，要求实现录制、试听、上传音频功能，选择的是getBackgroundAudioManager,声音录制和播放波形图是用css实现的，效果图及详细设计代码如下：
xml文件
录制提示 00:00:{{currentTime}} 开始 录好了 试听 上传 上传中 重新录制
js文件
let windowHeight = wx.getSystemInfoSync().windowHeight // 屏幕的高度
let screenWidth = wx.getSystemInfoSync().screenWidth
let screenHeight = wx.getSystemInfoSync().screenHeight
let cOntentHeight= ((windowHeight / screenWidth) * 750 - 184 - 166) + "rpx";
const recorderManager = wx.getRecorderManager()
const backgroundAudioManager = wx.getBackgroundAudioManager()
