How to set encode and format? Any examples of parameters?

thank you :)

[cmckni3]

are you using vue.js? should it be something like this for your data and mounted?

export default {
  data: function() {
    return {
      player: new Audio.TNSPlayer(),
      recorder: new Audio.TNSRecorder(),
      recording: false,
      audioPath: `${knownFolders.currentApp().getFolder('audio').path}/record.mp3`
    }
  },

  mounted: function() {
    this.recorder.debug = true
  },
...
}

Hi @yoking-shi
I have read (I don't remember where xD), you must set manually the value you want to use, you can see all value on this page: https://developer.android.com/reference/android/media/MediaRecorder.AudioEncoder
for example 3 for AAC encoding: https://developer.android.com/reference/android/media/MediaRecorder.AudioEncoder.html#AAC

bye 👍
