Sometimes I come across something that I want to share:

Nuit Blanche from Spy Films on Vimeo.

There’s a making of video too.

// Anything to the right of these two slashes is
// A comment and will not be part of the code.

var xSize:int = 200;

// Add an event listener to the stage and name the function
stage.addEventListener(Event.ENTER_FRAME,onFrameLoop);

// Your function name must match the name after the comma
// in the parenthesis.
function onFrameLoop(evt:Event):void {

// These are all of the things that will happen in
// the function.

// This will rotate the instance of the rectangle
// colin according to mouse X and Y values.
colin.y = mouseY;
colin.x = 800 - mouseX;

// here’s an if statement
if (mouseX > xSize) {
trace(”rotating! ” + mouseX +” ” + colin.y);
//colin.rotation = mouseX;
colin.height = 29;
// here’s another option if that statement hasn’t been met
}
else if(mouseX < xSize) {
trace(”scaling!”);
colin.scaleY = mouseY;
}
// This will scale the instance of the rectangle
// colin according to the mouse X and Y values.
colin.scaleX = mouseY/20;
colin.scaleY = mouseX/20;

}

// Don’t forget to close the function with the
// brace (squiggly bracket) above!!!

Take your inputs and organize them in the following way:

1. Time–time is elastic and relative, use your best judgement.
2. Action–what were you doing at that time?
3. Sense–requirement: use iconography
4. Location–where were you? can you be more specific?

Welcome back! You can search these pages for useful code and material from previous systems classes.

Here is our class syllabus in PDF format.

Update: Here’s a fabulous explanation on the getSpectrum() class for Flash.

I’ve compiled a list of basic resources for you to play around with before class on Wednesday in case you haven’t found these already. If you’re working with Processing, remember to place your sound file inside of a folder called “data” inside of your sketch’s folder. If you’re using flash, remember that computeSpectrum only deals with two channel audio (for our purposes right now this is OK). I also placed some code at the end of this post that uses beat detect. You will be able to tell the difference between beat detect and Minim’s standard volume.get by the blue flashiness. Enjoy!

Processing with Ess

Showing the level from an FFT with color

Showing a level of volume across frequency using color

Processing with Minim

Getting volume data in time (without an FFT)

Flash

computeSpectrum reading (a variation of the example I used in class) a sound file

Minim–BeatDetect Example

// Example By Colin Owens

import ddf.minim.*;

import ddf.minim.analysis.*;

Minim minim;

AudioPlayer song;

BeatDetect beat;

int multiplier = 10;

int count = 0;

int dotSize = 5;

void setup()

{

  size(1024, 768);

  minim = new Minim(this);

  song = minim.loadFile("true.mp3");

  song.play();

  beat = new BeatDetect();

}

void draw()

{

  background(0);

  beat.detect(song.mix);

  for(int i = 0; i < song.bufferSize() - 1; i++)

  {

    noStroke();

    fill(210,180,20);

    smooth();

    ellipse(count*multiplier, height/3 + song.left.get(i)*250, dotSize, dotSize);

    ellipse(count*multiplier, (height/3)*2 + song.right.get(i)*250, dotSize, dotSize);

if ( beat.isOnset() ) {

  fill(20,180,210);

   ellipse(count*multiplier, height/3 + song.left.get(i)*250, dotSize*10, dotSize*10);

    ellipse(count*multiplier, (height/3)*2 + song.right.get(i)*250, dotSize*10, dotSize*10);

}

    count++;

    if (count >= width) {

      count=0;

    }

    if (dotSize <= 0) {

      dotSize=1;

      multiplier = 10;

    }

  }

  if(keyPressed) {

    if (keyCode == LEFT) {

      multiplier = multiplier -1;

      dotSize = dotSize -1;

    }

    if (keyCode == RIGHT) {

      multiplier = multiplier +1;

      dotSize = dotSize +1;

    }

  }

}

void stop()

{

  song.close();

  super.stop();

}
