Forgive me if what I'm about to say seems silly, this is my first time using waveSurfer. Anyway, I have to extract pitch values for a number of raw speech files and I have been following tips from previous Forum messages and have been able to output text files with the pitch values. I am using the script as in http://www.speech.kth.se/snack/tutorial.html#batch saved in a text file. I run the script using the Console window's File menu and for a certain speech file I get 512 pitch values (including the unvoiced "zeros"). To test and see if the script was working, I opened the same file via Wavesurfer and on the pitch pane, I right clicked and saved the pitch values to another text file. This time, I get 1027 pitch values (including the unvoiced "zeros"). Clearly the parameters are different between both approaches. How can I fix this, or which should I trust more??? The speech file I tested has, according to wavesurfer, 10.304 seconds in duration, sampled at 8KHz.
I thank in advance for your help.

Please disregard my previous message. I saw that the default sampling rate is 16KHz. My speech files are at 8kHz. I have fixed my script file and everything is OK now.
