Jad Atoui – processing 10.2
I made a class that handles the sound objects and their status. I also envision making classes for slider and combing the sound and slider classes into a wrapping class called channel that manages the entire channel of sound.
An issue is related to the graphics and media contexts, where i need to construct the movie object at the top appellation
new Movie(this, file)
“this” for this constructor is not well documented on the processing site and seems very inflexible .
//Sampler.pde main sketch
int LENGTH = 3;
String BASE_FILENAME = “sample”;
Sample[] sounds = new Sample[LENGTH];
PImage pauseIcon;
PImage playIcon;
int offset = 600;
int[] sliderY = new int[LENGTH];
void setup() {
size(1600,1200);
println(this);
//This is a for loop that load the 3 samples and initialises the status to 0 .
for(int i=0; i < LENGTH; i++) {
String file = BASE_FILENAME + String.valueOf(i) + “.wav”;
Movie sound = new Movie (this,file);
sounds[i] = new Sample(sound);
sliderY[i] = 365;
}
// here load the pause and play icons
println(“we are done”);
playIcon = loadImage(“play.png”);
pauseIcon = loadImage(“pause.png”);
colorMode(RGB, 100);
}
void draw() {
background(0);
noStroke();
drawInterface();
}
// draw ALL the buttons and the sliders for each sound – spacing icons and on off button
void drawInterface() {
for(int i=0; i < LENGTH; i++) {
int x = i*140 + offset;
int y = offset;
drawButton(i,x,y);
drawSlider(i,x,y);
}
}
//differciaion of the buttons
void drawButton(int index, int x, int y) {
if(sounds[index].getStatus() == 1) {
fill(25,255,25,60);
rect(x,y,101,101);
image(pauseIcon,x,y);
}
else {
fill(255,25,25,60);
rect(x,y,101,101);
image(playIcon,x,y);
}
}
void mouseDragged(){
// if(mouseX >= x && mouseX <= x+rectW && mouseY>= y && mouseY<=Y+rectH){
for(int i=0; i < LENGTH; i++) {
if(mouseX >= (offset+20+140*i) && mouseX <= (offset+80+140*i) ) {
println(mouseX);
println(i);
sliderY[i]= mouseY;
sliderY[i] = constrain(sliderY[i],200,530);
//change
float speed = map(sliderY[i],200,530,0.0,2.0);
sounds[i].changeSpeed(speed);
}
}
}
void drawSlider(int index, int x, int y) {
//stroke(255,0,0,100);
fill(125,125,125,65);
rect(x+20,y-400,60,360);
//draw the slider button
fill(255,0,0,60);
rect(x+20,sliderY[index],60,30);
}
void drawIcon(int index, int status) {
}
void mousePressed() {
// if(mouseX >= offset && mouseX <= (140+offset) && mouseY >= offset && mouseY <= offset+101) {
// toggleSound(0);
// }
// else if(mouseX >= offset && mouseX <= (140*2+offset) && mouseY >= offset && mouseY <= offset+101) {
// toggleSound(1);
// }
// else if(mouseX >= offset && mouseX <= (140*3+offset) && mouseY >= offset && mouseY <= offset+101) {

// }
}
void keyPressed() {
if(key == ‘f’)
toggleSound(0);
else if(key == ‘g’) {
toggleSound(1);
}
else if(key == ‘h’) {
toggleSound(2);
}
}
//This funtion toggle the sound on and off depending on the status
void toggleSound(int index) {
sounds[index].toggleSound();
}
//Sample.pde
//this class manages a single sound
import processing.video.*;
public class Sample
{
int status;
Movie sound;
public Sample(Movie sound) {
this.sound = sound;
status = 0;
}
public void changeSpeed(float speed) {
sound.speed(speed);
}
public void toggleSound() {
if(status == 0) {
stopSound();
}
else {
playSound();
}
}
public int getStatus() {
return status;
}
protected void stopSound() {
status = 1;
sound.stop();
sound.loop();
}
protected void playSound() {
status = 0;
sound.stop();
}
}
P.S : I can’t ipload the web export because of the Movie class .
