哪种 AudioEncoder 编解码器最适合在 android 上录制最高质量的音频

Question

I am recording both audio and video on my Xamarin.Forms project. Some people tell me that when they use it the audio quality is low when recording. After some research I think it has something to do with the encoder.

This is my line for setting the codec

 this.mediaRecorder.SetAudioEncoder(AudioEncoder.Aac);

And here are the available encoder options

In some threads I see people recommend using AmrNb or Aac (which I already use). I tried all options and can't see any noticeable difference.

Which one is best for recording audio on smartphones?

Should I manually set audio bitrate, and if yes how do I determine it?

Answer 1

 this.mediaRecorder.SetAudioSource(AudioSource.VoiceRecognition);           
 this.mediaRecorder.SetAudioEncodingBitRate(128000);
 this.mediaRecorder.SetAudioSamplingRate(16000);

I added these lines ( basically I increased the bitrate and changed audio source) and I think it's better now.
