Description
every time I try to play an mp3 sound file in processing I get the following error
INFO: Pure Java JSyn from www.softsynth.com, rate = 44100, RT, V16.8.0 (build 463, 2017-10-16)
ArrayIndexOutOfBoundsException: 3
when I try .wav files I get the following error
Sound library error: unable to decode sound file hopping.wav
here's the relevant code:
import processing.sound.*;
SoundFile file;
void setup() {
file=new SoundFile(this,"hopping.wav");
file.play();
}
I double checked, the files are in the sketch's data directory.
I've tried on my desktop Mac and my laptop running windows. Same error on both.
