Processing Code 11/29

There is a problem with the .wav and timing of the color changes. We are wondering if this is a Processing or Sonia issue. This code uses for loops and arrays to cut down on file size.

// CODE

// SONIA V2.5 -- Audio Live Stream.

//http://www.pitaru.com/sonia/

//Goal is to capture audio data and parse into if/then statements

//Note the Sonia code folder goes into the sketch folder

int numOfPics = 5;                       //number of images in image array for colors

BImage[] colors = new BImage[numOfPics]; //new array of up for displaying color photos

int picDislayTime = 100000;                //time image is displayed in milliseconds



int whichImage = 0;

int startTime;

Sample thunder;

float previousLevel = 0;

boolean showing  = false;



void setup()

{

  Sonia.start(this);    // Start Sonia engine.

  LiveInput.start(256); // Start LiveInput and return 256 FFT frequency bands.



  thunder = new Sample("thunder.wav");



  size(640,480);

  

  for(int j=0 ; j<5  ; j++)

  {

    int m = j+1;

    colors[j] = loadImage("color" + m + ".gif");

  }

  startTime = millis();

}



void loop()

{



  showImage();      //Show appropriate image based on input from microphone



  for(int i = 5 ; i > 0  ; i-=1)

  {

    int j = i-1;

    if (showing)



    if (whichImage == i) {

      image(colors[j], 0, 0);

    }    

    if ((millis() - startTime > picDislayTime) || (1500 * LiveInput.getLevel(Sonia.LEFT) > previousLevel))

    /* || (1000 * LiveInput.getLevel(Sonia.LEFT) < previousLevel)*/{

      showing = false;

    }

  }

}



void showImage()//Show image based on input from microphone

{

  float meterDataLeft = 1500 * LiveInput.getLevel(Sonia.LEFT);//avg this w/ serial in



  for(int i = 800 ; i > 100  ; i-=160)

  {

    int j = i/160;



    if (!showing)

    {

      if (meterDataLeft > i)

      {

        whichImage = j;

        println(j);

        thunder.play();

        showing = true;

        startTime = millis();

        previousLevel= meterDataLeft;

      }

    }

  }

}

// Safely close the sound engine upon Browser shutdown.

public void stop(){

  Sonia.stop();

  super.stop();

}
