I wasn’t expecting to be able to create such direct way of creating the image at such an early point, I expected this to come later, maybe after the first term was over and I could work on this whilst the Arduino and Physical computing workshop in january. I was direct to to simple example call //get line in by Damien Di Fede.
I’ve looked at the code alittle, but not yet found a way of using it to my advantage, but I’m hoping to be able to create a way for the drawing to start a new “random” line once the peek of the audio reaches a certain point, more to follow…….
import ddf.minim.*;
Minim minim;
AudioInput in;
void setup()
{
size(512, 200, P2D);
minim = new Minim(this);
minim.debugOn();
// get a line in from Minim, default bit depth is 16
in = minim.getLineIn(Minim.STEREO, 512);
}
void draw()
{
background(0);
stroke(255);
// draw the waveforms
for(int i = 0; i < in.bufferSize() – 1; i++)
{
line(i, 50 + in.left.get(i)*50, i+1, 50 + in.left.get(i+1)*50);
line(i, 150 + in.right.get(i)*50, i+1, 150 + in.right.get(i+1)*50);
}
}
void stop()
{
// always close Minim audio classes when you are done with them
in.close();
minim.stop();
super.stop();
}////end
