マイクからの録音は終了しましたが、録音を終了することはできません

Question

processing.orgのサンプルファイル（Win8）を使用して、「マイクから録音」を取得してサウンドを再生しました。私は一度に10〜30秒を記録するだけです。しかし、現在、既存の録音を閉じて新しい録音を録音する方法はありません。
私はすでにあらゆる方法を試みました。私は別のキーを押すことができるようにしたい、 "r"をもう一度押して、語彙の練習などのようにもう数秒を記録したい。
私はcompartmental.net/minimの最小サンプルコードを使用しています。公式ドキュメントにはbeginRecord/endRecordのリストがありますが、既存の録音を閉じて別の録音を開始する方法はありません。 recorder.closeとしてはそのようなものはありません（）または.RESET /再起動など

{ size(512, 200, P3D); 
    minim = new Minim(this); 
    in = minim.getLineIn(Minim.STEREO, 2048); 
    // create an AudioRecorder 
    recorder = minim.createRecorder(in, "myrecording.wav");

    else if (!recorded) 
    { text("Press the R key to start recording.", 5, 15);  } 
    else 
    { text("Press the S key to save the recording to disk and play it back in the sketch.", 5, 15); } 
} 
//end draw 
void keyReleased() 
{ 
    if (!recorded && key == 'r') 
    { // to indicate that you want to start or stop capturing audio data, 
      if (recorder.isRecording() ) 
      { recorder.endRecord(); 
       recorded = true;    } 
    else 
    { recorder.beginRecord();  } 
    } 
    if (recorded && key == 's') 
    { // now write it to file 
    // case of buffered recording, will freeze sketch for a bit if buffer is large 
    // case of streamed recording, will not freeze all that is being done 
    // all that is being done is closing the file. 
    // save returns the recorded audio in an AudioRecordingStream, 
    // which we can then play with a FilePlayer 
    if (player != null) 
     { player.unpatch(out); 
       player.close();   } 
    player = new FilePlayer(recorder.save()); 
    player.patch(out); 
    player.play(); 
    } 
    // my addition — this works for play-again 
    if (recorded && key == 'p') 
    { player.rewind(); 
    player.play(); 
    } 

私はミニムをクローズして再起動しますが、それは文句を言うてみましたがそうのような「ローカル変数xxxが使用されていません」 ： 動作しません。

if (key == 'x') 
    { minim.stop(); 
    minim = new Minim(this); 
    AudioInput in; 
    AudioRecorder recorder; 
    AudioOutput out; 
    FilePlayer player; }

あなたは、単にレコーダーを再初期化して逃げることができます：あなたは、以前の録音を上書きしないように、私は、タイムスタンプやファイルカウンタを使用することをお勧めします

recorder = minim.createRecorder(in, "myrecording.wav"); 

。あなたはむしろ使用したい場合は

/** 
    * This sketch demonstrates how to an <code>AudioRecorder</code> to record audio to disk. 
    * To use this sketch you need to have something plugged into the line-in on your computer, 
    * or else be working on a laptop with an active built-in microphone. 
    * <p>
