MediaRecorder recorder = new MediaRecorder();
File outputFile = new File(Environment.getExternalStorageDirectory(), "audio.3gp");
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(outputFile.getAbsolutePath());
recorder.prepare();
recorder.start();
// stop
recorder.stop();
recorder.reset(); 
recorder.release();

推荐答案

AMR_NB 很糟糕.

AMR_NB stinks.

将比特率设置为 16，采样率设置为 44100.

Set the bitrate to 16 and sampling rate to 44100.

3gpp 通常很糟糕，请尝试改用 AAC/MPEG_4.

3gpp generally stinks, try using AAC/MPEG_4 instead.

试试这个并更新我们.
