Answers.Body: <p>That is not possible because MIDI is not an audio file format. It's a <a href="http://en.m.wikipedia.org/wiki/MIDI" rel="nofollow">description on how to create music</a>.

  There are several tools out there. The free but rather dated [AmazingMIDI](http://www.pluto.dti.ne.jp/~araki/amazingmidi/) which takes in `.wav` files and generates the corresponding MIDI. You can convert to `.wav` from `.mp3` using [Audacity](http://web.audacityteam.org/) or ffmpeg.
  
  Then there are a few commercial products such as [AthTek DigiBand](http://www.athtek.com/digiband.html), [WidiSoft](http://www.widisoft.com), and others.
