What are you trying to achieve?:
I’m pretty new to psychopy and python so I only have a basic understanding of coding, and I’m using the Builder. I’m trying to use the code component to play a short sound at 8 different timepoints in a routine without having to add 8 different sound components.
So far, I can get a sound to play ‘properly’ (i.e. once when I want it to) at about 1 seconds, 2 seconds, and 3 seconds after the routine begins if I include this code in the Begin routine tab:
spring = sound.Sound('folder/spring1.wav') springTime = [60, 120, 180]
and this in the Each Frame tab:
if frameN in springTime: spring.play()
However, the timing never quite lines up with the other components which are scheduled to start on a specific second, and I’d like to know how to code sounds and other stimuli to start by seconds instead of frames.
Unfortunately, I haven’t had a lot of luck. For example, I was trying to code the sound to play at 1 second. If I write this into the Each Frame tab:
if t == 1: spring.play()
Nothing plays, which I understand is because the frames doesn’t match up perfectly with the time. But, if I do this
if t >= 1: spring.play()
then after a second has past, the spring noise starts playing over and over again instead of just playing once.
I’m sure I’m missing something obvious. I’ve tried playing around with the code component and had no luck. I couldn’t reverse engineer an answer from the generated code for the sound component. I’ve tried looking it up, but nothing I’ve found explains how to use the t variable like this.
Can anyone help?
