Sound in Processing

Today we worked with a library for sound called Minim. The homework for next time (not next week) is to make something using sound. Preferably using some of the graphic and interactive elements we've gone through before. Minim documentation

We moved on to a brief look into object oriented programming and on to play with sound using the Minim library. The full documentation is here.

Two of the classes we played around with was audioSample and audioPlayer.

Audiosample - short samples
import ddf.minim.*;
 
Minim minim;
AudioSample money, gun;
 
void setup()
{
  size(640, 480);
  // always start Minim before you do anything with it
  minim = new Minim(this);
  // load soundfile from the data folder
  money = minim.loadSample("CASH2.WAV");
  gun = minim.loadSample("SHOTGUN-X3.WAV");
 
}
 
void draw()
{
  //nothing to actually draw
}
 
void keyPressed()
{  
  if ( key == 'y' ) 
  {
    money.trigger();
  }
 
  if ( key == 'p' ) 
  {
    gun.trigger();
  }
}
 
void stop()
{
  // always close Minim audio classes when you are done with them
  money.close();
  gun.close();
  minim.stop();
}
AudioPlayer - longer audio files
import ddf.minim.*;
 
Minim minim;
AudioPlayer soundtrack;
 
void setup()
{
  size(640, 480);
  // always start Minim before you do anything with it
  minim = new Minim(this);
  //load a file, 
  soundtrack = minim.loadFile("song2.mp3");
}
 
void draw()
{
  //nothing to actually draw
}
 
void keyPressed()
{
  if ( key == 'q' ) 
  {
    if(soundtrack.isPlaying()) //checking if the song is playing to choose play/pause
     soundtrack.pause();
    else
     soundtrack.play();
  }
 
  if ( key == 'w')
  {
    soundtrack.skip(3000); //skipping three seconds
  }
 
  if( key == 'e')
  {
    soundtrack.rewind(); //well...yeah, guess. :-)
  }
}
 
void stop()
{
  // always close Minim audio classes when you are done with them
  soundtrack.close();
  minim.stop(); 
}
 
Concepts we worked with
audioPlayer
play()
pause()
rewind()
isPlaying()
position()
skip()
cue()
 
 
audioSample
trigger()
length()
stop()
