I want to get the Intensity readings of a sustained vowel at even time intervals (i.e. every 0.01 or 0.001 seconds). In Praat when I adjust the time step to "fixed" and change the fixed time to 0.01 or 0.001 it adjusts this for pitch and formants, but not for intensity. Intensity remains at increments of 0.010667 seconds between each time. Is it possible to change the time step for intensity or can it only be changed for the other parameters? Any help is much appreciated!
Hi Adam,
just checked it - yes 0.010667 s seems to be Praat's standard for reports in the default Edit window. However, you may want to consider transforming your wav data to an Intensity object (I think you can specify the time steps here directly) or you take your data to Matlab. What is the reason you need such a fine precision for Intensity measurements?

What you actually want to change is the window size. For that you need to change the pitch settings and give a minimum pitch 4 times more than the rate you want rate you want to have (i.e. 400/4000 for a window size of 0.ü1/0.001). This will however not change the overall mean intensity much, and is more relevant to clinical research.
Thank you Yshai and Xaver for your responses! Setting the pitch minimum to 400 did what I needed. I'm analyzing speech recordings for clinical research and I wanted to have an even interval of time for my matlab script.
