How to use the recording feature in WeDa

Requires the use of RecorderManager (the globally unique audio recording manager) in WeChat Mini Program development.

Recording Process​

  • The user enters the page and loads the RecorderManager instance for audio recording.
  • Start recording
  • After recording is completed, stop the recording.
  • Retrieve the temporary recording file via RecorderManager.onStop()
  • Upload the temporary file to the cloud server via wx.uploadFile
  • Convert cloud service file id to https URL
  • The page displays the recording file for user playback. image.png

Sample code​

const recorderManager = wx.getRecorderManager()
recorderManager.onStart(() => {// Listen for the start of recording
  console.log('recorder start')
})
recorderManager.onPause(() => {// Listen for the pause of recording
  console.log('recorder pause')
})
recorderManager.onStop((res) => {// Listen for the stop of recording
  console.log('recorder stop', res)
  const { tempFilePath } = res
})
recorderManager.onFrameRecorded((res) => {
  const { frameBuffer } = res
  console.log('frameBuffer.byteLength', frameBuffer.byteLength)
})
const options = {//Recording configuration
  duration: 10000,
  sampleRate: 44100,
  numberOfChannels: 1,
  encodeBitRate: 192000,
  format: 'aac',
  frameSize: 50
