matlab session on pitch tracking using harmonic product spectrum

I'm hoping to implement a working matlab algorithm based on the HPS method.
Some information on it:

• http://www-ccrma.stanford.edu/~pdelac/220c/Presentation/img1.htm
  A short image-based explanation of the algorithm and some parameters of it
• http://cnx.org/content/m11714/latest/
  A post about pitch detection explaining HPS too.

Much time 'lost' on the weekly meeting.
I started implementing HPS, but I'll continue tomorrow, nothing worth to say for now.
I also tried the frame-by-frame idea. Have to study it, but I made an implementation in the thesis folder on ESAT.




In between the soup and potatoes (dutch saying) I added a mixer section to the applyEffect algorithm:

%% mixer
inputSignalMixer = outputSignalEffect(1:length(originalSignal)); % cut any extra samples away for the wet and dry signals to match
outputSignalMixer = wet * inputSignalMixer + (1 - wet) * originalSignal; % mix wet and dry signal
