title: How to get started with jtransforms library in Java
body: <p>I want to extract frequencies from a wav audio and i'm thinking of using an autocorrelation method along with the usage of FFT. </p>
  
  <p>Came accross a good pitch detection library for java called "JTransforms" can anyone suggest how to get started with it? Code snippets would be ideal.</p>
  
  <p>Thanks</p>
