title: function to compare two single byte elements
body: <p>I'm recording sounds and saving them into a byte[] buffer. Now I want to compare every single element of those two list, to know how different they are. Could anyone tell me wich is the best method to do that? I have read on here Array.equal(array1,array2), but I want to compare just two elements in each iteration and I want the position of the different bytes as well.</p>
