title: Is comparing two audio files using FFT the only way?
body: <p>I am new to signal processing and trying to compare two audio files using FFT. 
  Reading the file to bytes and then converting to complex numbers and then sending it to fft.
  Then calculated magnitude of the complex numbers(output from fft). Trying to compare the magnitude but they are not matching.</p>
  
  <p>Please let me know if i am missing anything.</p>
  
  <p>Is there any other way to compare two audio files?</p>
