Hey everyone, 
   I have been looking everywhere for the answer to the right audio program, but I have found nothing.  I decided to come here since I know there are a lot of great people. 
Basically, I have two wave files that are nearly identical, yet have a few minor differences between them.  The thing is, I want to extract only the similar areas from the waves, while removing all of the differences, so I can work with them better.  Does anyone know of a program that can do this? 
Any help is appreciated.
