title: "Unexpected token: Void" error in processing IDE caused by for loop regardless of position?
body: <p>I'm currently trying to code a simple audio delay sketch in the processing IDE. I keep getting an "unexpected token: Void" error pointed at my Void Setup() function. If I comment out the contents of this for loop:</p>
  
  <pre><code>for (int i = 0; i &lt; output.length; i++)  
  {  
      output[i] = (audioData[i]+audioData[i-44100];  
  }
  </code></pre>
  
  <p>then this error does not appear. This error occurs regardless of which function i put this loop in, and I've tried coding it in alternate ways. No luck.</p>
  
  <p>Here's the code for the tab that's giving me trouble:</p>
  
  <pre><code>AudioThread audioThread;
  // we'll use this to store the audio data we read from the audio file
  float[] audioData;
  float[] delayData;
  // we'll use this to remember our position in the audio data array
  float readHead;
  float readHeadDelay;
  
  void setup() {
      size(500, 400, P2D);
      // the audio file we want to play, which should be in the data dir
      String audioFilename = "myk_hats_dub1.wav";
  
      // read the audio data into a float array using the AudioFileIn class
      audioData = new AudioFileIn(audioFilename, this).getSampleData();
      delayData = new AudioFileIn(audioFilename, this).getSampleData();
  
      // print how many samples we read
      println("Read " + audioData.length + " samples");
      // set the read head to zero, the first sample
      readHead = 0;
      readHeadDelay = 44100;
      // start up the audio thread
      audioThread = new AudioThread();
      audioThread.start();
  }
  
  void draw() {
      background(255);
      fill(0);
  }
  
  // this function gets called when you press the escape key in the sketch
  void stop() {
      // tell the audio to stop
      audioThread.quit();
      // call the version of stop defined in our parent class, in case it does
      // anything vital
      super.stop();
  }
  
  // this gets called by the audio thread when it wants some audio
  // we should fill the sent buffer with the audio we want to send to the
  // audio output
  void generateAudioOut(float[] buffer) {
  
      for (int i = 0; i &lt; buffer.length; i++) {
  
          // copy data from the audio we read from the file (audioData)
          // into the buffer that gets sent to the sound card
          buffer[i] = audioData[(int) readHead];
  
          // add a sample from the other array
          buffer[i] += delayData[(int) readHeadDelay];
          // scale it so it does not go over 1.0
          buffer[i] *= 0.5;
  
          // move the read head along one, resetting to zero
          // if it goes to the end of the audioData array
          readHead++;
          readHeadDelay++;
          if (readHead &gt;= audioData.length) {
              readHead = 0;
          }
          if (readHeadDelay &gt;= delayData.length) {
              readHeadDelay = 0;
          }
      }
  
  }
  </code></pre>
  
  <p>can anyone help?</p>
