title: Beat extraction in MATLAB
body: <p>I have no experience in MATLAB and unfortunately my project is in MATLAB.</p>
  
  <p>Basically the objective is to read a music source (preferably in mp3 format but .wav is also OK) into MATLAB and then apply a low pass filter in such a way that it filters everything except the beats. Then it should get the time at which each beat occurs and write the results to a text file.</p>
