title: How to recognize a musical tone in Android?
body: <p>I'm developing an Android application, what that i need is recognize a musical tone, for example, if you took my guitar and you played a <strong>C</strong> I would like my application was able to tell me the note that I played.</p>
  
  <p>The basic operation would be simple, and the sound from the microphone recorded through some sort of recognition would have the output of which I need.</p>
  
  <p>The only one thing that i don't know is: it is possible do this ?</p>
  
  <p>If is yes, is it possible recognize more than one notes over a period of time?</p>
