Audio recording in Android, how to customize the recording experience?

I am recording Audio using,

Intent intent = new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);

atartActivityForResult(intent, 1); // intent and 开发者_如何学GorequestCode 1

In the protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (requestCode == 1) {
   ...
              // lets get the uri
            Uri audioUri = data.getData();

'''

So, I have a audio pointed by audioUri.

1. How can I save a file from this Uri? Please also tell the format of audio.

2. Is it possible to change the look and feel of the GUI of the audio interface ..., i mean the interface that we see at the time of recording..

thanks
