How to call recording and play recording in WeChat applet

This time I will show you how to call recording and playback of recording by WeChat applet. What are theprecautionsfor WeChat applet to call recording and playback of recording. The following is a practical case, let’s take a look.

The mini program provides two recording APIs

Old version recording function

First start recording, then stop recording to pull to the temporary address ofaudio

Start recording:

var that = this; wx.startRecord({ success: function (res) { // 调用了停止录音接口就会触发这个函数，res.tempFilePath为录音文件临时路径 var tempFilePath = res.tempFilePath that.setData({ src: tempFilePath }) }, fail: function (res) { //录音失败的处理函数 } })

Stop recording:

wx.stopRecord()

Play recording:

wx.playVoice({ filePath: src // src可以是录音文件临时路径 })

New version recording

Get the globally unique recording manager, and then all recordings depend on it, and playing the recording requires the internal audio context innerAudioContextObject.

Get the globally unique recording manager:

var that = this; this.recorderManager = wx.getRecorderManager(); this.recorderManager.onError(function(){ // 录音失败的回调处理 }); this.recorderManager.onStop(function(res){ // 停止录音之后，把录取到的音频放在res.tempFilePath that.setData({ src: res.tempFilePath }) console.log(res.tempFilePath ) });

Start recording:

this.recorderManager.start({ format: 'mp3' // 如果录制acc类型音频则改成aac });

End recording:

this.recorderManager.stop()

Play audio:

this.innerAudioContext = wx.createInnerAudioContext(); this.innerAudioContext.onError((res) => { // 播放音频失败的回调 }) this.innerAudioContext.src = this.data.src; // 这里可以是录音的临时路径 this.innerAudioContext.play()
