How to record audio file in Android

I am working in android. How can I record an audio file through microphone, and how can I save the recorded file in the emulator?

Solution

  • It is easy to record audio in Android. What you need to do is:

    1) Create the object for media record class : MediaRecorder recorder = new MediaRecorder();

    2) In the emulator, you're unable to store the recorded data in memory, so you have to store it on the SD Card. So, first check for the SD Card availability: then start recording with the following code.

    String status = Environment.getExternalStorageState();
if(status.equals("mounted")){
   String path = your path;
}

recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();

    3) To stop, override stop method of activity

     recorder.stop();
 recorder.release();
