Noise stim function - when to update

PsychoPy version : 2022.2.5


I have a question about the “how to update noise sample” function :

I want my noise updating every frame of my screen (100hertz). What do I have to write for this function? 1/100?

Thanks in advance for your response,


Hello Elise

did you try setting When to update noise sample to 1? You could test slower update frequencies first.
