提高Android的音频录制质量？ [英] Improve Audio Recording quality in android?

问题描述

我现在用的是 MediaRecorder 音频录制的机器人。我收到的时候我记录很差的音频质量。我查了一下iPhone的记录，这是非常好的，但在Android的我收到可怕的声音。

I am using the MediaRecorder for audio recording in android. I receive very poor audio quality when I record. I checked iPhone recording, and it is very good, but in android I receive horrible sound.

有关录音我使用：

 recorder = new MediaRecorder();
 recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
 recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
 recorder.setAudioEncoder(MediaRecorder.AudioSource.DEFAULT);
 recorder.setOutputFile(path);
 recorder.prepare();
 recorder.start(); 

如何提高录音质量？

recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setAudioEncoder(MediaRecorder.getAudioSourceMax());
recorder.setAudioEncodingBitRate(16);
recorder.setAudioSamplingRate(44100);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
