Playing a repeating sound in a random time interval

What are you trying to achieve?: I am trying to run a test that shows a series of videos (loaded from disk) and along with the videos have a sound playing that is triggered every 1-1.5 seconds and lasts around 0.7 seconds.

What did you try to make it work?: I’ve created a Flow with all the videos loaded in different routines, the videos are displaying correctly. But for the sound i did a python script that uses winsound.beep() to trigger the beeping sound. I try running this method using

  • multiprocessing
  • threading

What specifically went wrong when you tried that?:
for the first the flow didn’t even display correctly, just freezes on loading and crashes soon after. When using threading the flow is started but the videos are been display at 1-2 fps and skipping all the missing frames.

So basically thats what i’m trying to do. play a beeping sound along side the videos that triggers in a random time between 1-1.5 seconds? any ideas that could help me? much appreciated.

Include pasted full error message if possible. “That didn’t work” is not enough information.

Hi There,
