title: compare two audio file in java
body: <p>i want to make a project in which i am going to record a user's voice and then compare it with a stored voice. I searched for that and i come up with MFCC and FTT algorithm. but i really don't understand that how they work.Only theory i found on internet not any practical knowledge. I don't have an electrical background so not so much knowledge about waves and signal.</p>
  
  <p>I found that there are some features of voice like 
  -pitch
  -amplitude
  -frequency
  -energy </p>
  
  <p>is there any way to calculate all these through coding. My project is in java.If anyone has some information regarding this so please help me.</p>
