Audio file .wav gives error (what are requirements for wav file to be loaded?)

naomihanemaaijer

Hello,

I would like to change an audio file in my code but everytime an error occures, where with the previous file it works. All I do is change the name of the audiofile (both files are in the same folder and .wav). I suppose there is something wrong with the file, but I can't figure out how to fix this. I'm new to processing and have to work with someone elses code, unfortunately i don't have time to figure out processing or this code completely and I've been googling the error for a while, but still can't figure it out.. I'm sorry if this is a bit of a stupid question. Is there someone with a (simple) explanation? I work on a windows laptop, with processing 2.1.1. I use "Praat" to produce the .wav files. If this is not enough information to answer my question, please let me know. Thanks a lot!

Here's the code (all I changed was "green_stream" and "red_stream"):

    String[] stimuli = {
    "green_stream.wav",//0
    "red_stream.wav",//1

and a bit further (I'm not sure this is relevant):

  in = minim.loadSnippet("stimuli/"+stimuli[stimulus]);
  meta = in.getMetaData();
  stimulus_duration = meta.length();
  soundLoaded = true;

This is the error:

==== JavaSound Minim Error ==== ==== Unable to return a SourceDataLine: unsupported format - PCM_SIGNED 44100.0 Hz, 24 bit, mono, 3 bytes/frame, little-endian

=== Minim Error === === Couldn't load the file stimuli/red_stream.wav

Got it. All I had to do was update Java... Total noob. Never mind!
