cannot convert from AudioSample to AudioSample (minim)

feroz1996 · March 2015

Hey all,

I was trying to use minim in one of my other projects and was running into issues so I made this very simple program to test things out... I get a "cannot convert from AudioSample to AudioSample" error..? This seems to be the exact implementation from the examples at: http://code.compartmental.net/minim/audiosample_class_audiosample.html.

import ddf.minim.*;
Minim minim;
AudioSample sample;
AudioPlayer player;

void setup(){
  minim = new Minim(this);
  minim.debugOn();
  sample = minim.loadSample("tamb.wav");
  //player = minim.loadFile("tamb.wav");
}
void draw(){

}
void mouseClicked(){
  sample.trigger();
  //player.play();
  //player.rewind();
}

When that didn't work I tried loading the same wav file, a <1 second tamborine sample if that matters, into AudioPlayer (commented sections of code above). It seemed to load in ok but when I tried to play it I got a Java.lang.ArrayIndexOutOfBoundsException: 15

minim debug (before playing):

=== Minim Debug ===
=== Likely buffer underrun in AudioOutput.

After trying to play:

Does anyone see anything wrong?

Howdy, Stranger!
