I'm working on a program that uses [Jlayer |http://www.javazoom.com/] gets decoded samples from a SampleBuffer to run through an FFT. It seems to work fine for the first two iterations. but after that i get "Exception in thread "AWT-EventQueue-0" Java.lang.ArrayIndexOutOfBoundsException: 433"
what is the reason? is this a problem with Jlayer or is it something else?
I'm using Netbeans so im not going to bother putting the generated code here. i set up the m_file property of my object in the constructor.
