title: frequency / pitch detection for dummies
body: <p>While I have many questions on this site dealing with the concept of pitch detection... They all deal with this magical <em>FFT</em> with which I am not familiar. I am trying to build an Android application that needs to implement pitch detection. I have absolutely no understanding for the algorithms that are used to do this.  </p>
  
  <p>It can't be <em>that</em> hard can it? There are around 8 billion guitar tuner apps on the android market after all. </p>
  
  <p>Can someone help?</p>
