How can I get sound to fade in and out depending on your location?

karinalopez87

Hello, I was able to make my sound play and stop with Kinect but it doesn't loop or fade out. I want my sound to continue playing with the video and just fade in if the interaction is activated and fade out when the interaction is no longer happening. Also, I want my sound to loop.

     import processing.sound.*;
     import org.openkinect.processing.*;
     import processing.video.*;


    Movie vid;
    Movie vid1;
    SoundFile sound1;
    SoundFile sound2;
    Kinect2 kinect2;

    //PImage depthImg;
    //PImage img1;

    //pixel
    int minDepth=0;
    int maxDepth=4500; //4.5m

    boolean off = false;

    void setup() {
      size(1920,1080);
      //fullScreen();
      vid = new Movie(this, "test_1.1.mp4");
      vid1 = new Movie(this, "test_1.1.mp4");
      sound1 = new SoundFile(this, "cosmos.mp3");
      sound2 = new SoundFile(this, "NosajThing_Distance.mp3");

      //MOVIE FILES
          //01.MOV
          //03.MOV
          //02.mov (File's too big)
          //Urban Streams.mp4
          //HiddenNumbers_KarinaLopez.mov
          //test_w-sound.mp4
          //test_1.1.mp4
          //test005.mov
      //SOUND FILES      
          //cosmos.mp3
          //NosajThing_Distance.mp3

      vid.loop();
      vid1.loop();
      kinect2 = new Kinect2(this);
      kinect2.initDepth();
      kinect2.initDevice();
    //depthImg = new PImage(kinect2.depthWidth, kinect2.depthHeight);
    //img1 = createImage(kinect2.depthWidth, kinect2.depthHeight, RGB);
    }

    void movieEvent(Movie vid){
      vid.read();
      vid1.read();
    }


    void draw() { 
      vid.loadPixels();
      vid1.loadPixels();

      //image(kinect2.getDepthImage(), 0, 0);

        int[] depth = kinect2.getRawDepth();

      float sumX=0;
      float sumY=0;
      float totalPixels=0;

        for (int x = 0; x < kinect2.depthWidth; x++){
          for (int y = 0; y < kinect2.depthHeight; y++){
            int offset = x + y * kinect2.depthWidth;
            int d = depth[offset];

            if ( d > 0 && d < 1000){
          //    //video.pixels[offset] = color(255, 100, 15);
          sumX +=x;
          sumY+=y;
          totalPixels++;
             brightness(0);
            } else {
          //    //video.pixels[offset] = color(150, 250, 180);
              brightness(255);
            }      }
        }
    vid.updatePixels();
    vid1.updatePixels();

    float avgX = sumX/totalPixels;
    float avgY=sumY/totalPixels;


    //VID 01 - Screen 01
    if (avgX>300 && avgX<500){
    tint(255, (avgX)/2);
    image(vid1, 1920/2, 0);
    if(sound2.isPlaying()==0){
    sound2.play(0.5);
    sound2.amp(0.5);
    }
    }else{
    tint(0, (avgX)/2);
    image(vid1, 1920/2, 0);
    if(sound2.isPlaying()==1){
     delay(1);
    //IT DIMS THE VOLUME TO 0 BUT IT DOESN'T GO BACK TO VOLUME 0.5 [sound2.amp(0.5);]
     sound2.amp(0);
     }
    }
     //VID 02 - Screen 01
     if (avgX>50 && avgX<200){
    tint(255, (avgX)/3);
    image(vid, 0-(1920/2), 0);
    }else{
       tint(0, (avgX)/3);
       image(vid, 0-(1920/2), 0);
     }
    }

In Processing, press Ctrl+t to format your code in the PDE. Then copy and paste the code and format it in the forum (exactly as you have done above).

This could be relevant: https://forum.processing.org/two/discussion/25094/set-distance-value-with-ultrasonic-sensor#latest

Right now, what does your code do? Can you get any fading at all? Please notice we don't have the videos nor your setup (not kinect here). Can you comment on what type of kinect unit are you using?

For volume, check these:
