Pitch determination and voice quality analysis using subharmonic-to-harmonic ratio.
There are also some post-processing routines available, such as de-step filter, median filter, and linear filter. For more information, please see http://www.speakingx.com/blog/2008/01/02/pitch-determination

It seams that this program doesn't stop pitch calculation when it is silence. Hope add VAD~ hhh
Appreciate it!

In my program
[Y,Fs]=audioread('female.wav');
F0MinMax=[120,400];%female
%F0MinMax=[50 250];%male
frame_length=40;
timestep=10;
SHR_Threshold=0.4;
ceiling=1250;
med_smooth=0;
check_voicing=0;
[f0_time,f0_value,SHR,f0_candidates]=shrp(Y,Fs,F0MinMax,frame_length,timestep,SHR_Threshold,ceiling,med_smooth,check_voicing);

Error in shrp (line 93)
Y=Y-mean(Y); % remove DC component

an error is displayed saying that ' sampling frequency must be supplied #line 28 '.
can anyone help me please.. its urgent

Nice de-step filter !
Many thanks to Xuejing Sun for implementing the algorithm in Matlab and for acknowledging its origins.
