Minim Build Failing: Simple Record Audio Example

[internetsadboy]

Yo @AubG @Madslick,

If you have time, can you see if this example breaks?

I essentially yanked the example from minim. I imported all jars associated with minim, and added all minim jars to the build path; so I'm not sure why it's not working.

People had some similar issues on the interwebs. However, it had to do with importing all minim jars and I believe I've done that.

Any help is appreciated :hankey:

RecordAudio.java

Note: change the audio files in loadSample to random audio files on your machine :stuck_out_tongue:

import processing.core.*;

import ddf.minim.*;

public class RecordAudio extends PApplet
{
    Minim minim;

    AudioSample kick;

    AudioSample snare;

    public void setup ()
    {
      size(512, 200, P3D);
      minim = new Minim(this);

      // load BD.wav from the data folder
      kick = minim.loadSample("/Users/jhalpert/Downloads/Minim-2.2.0/examples/Basics/TriggerASample/data/BD.mp3", 512); // filename, buffer size

      // An AudioSample will spawn its own audio processing Thread, 
      // and since audio processing works by generating one buffer 
      // of samples at a time, we can specify how big we want that
      // buffer to be in the call to loadSample. 
      // above, we requested a buffer size of 512 because 
      // this will make the triggering of the samples sound more responsive.
      // on some systems, this might be too small and the audio 
      // will sound corrupted, in that case, you can just increase
      // the buffer size.

      // if a file doesn't exist, loadSample will return null
      if ( kick == null ) println("Didn't get kick!");

      // load SD.wav from the data folder
      snare = minim.loadSample("/Users/jhalpert/Documents/workspace/ProcessingContents/Java/modes/java/libraries/minim/examples/loadFileIntoBuffer/data/SD.wav", 512);
      if (snare == null) println("Didn't get snare!");
    }

    public void draw ()
    {
      background(0);
      stroke(255);

      // use the mix buffer to draw the waveforms.
      for (int i = 0; i < kick.bufferSize() - 1; i++)
      {
        float x1 = map(i, 0, kick.bufferSize(), 0, width);
        float x2 = map(i + 1, 0, kick.bufferSize(), 0, width);
        line(x1, 50 - kick.mix.get(i) * 50, x2, 50 - kick.mix.get(i+1) * 50);
        line(x1, 150 - snare.mix.get(i) * 50, x2, 150 - snare.mix.get(i+1) * 50);
      }
    }

    public void keyPressed () 
    {
      if (key == 's') snare.trigger();
      if (key == 'k') kick.trigger();
    }

}

I get the above error, and I am not sure as to why.

[internetsadboy]

Hmm weird, especially b/c it comes bundled w/ processing. The code works w/in "sketch."
