Two recording APIs are provided in the mini program
Old version recording function
First start recording, then stop recording to pull the audio Temporary address
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 of recording
Get the globally unique recording manager, and then the recording depends on it, and playing the recording requires the internal audio context innerAudioContext object.
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()The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
