I want my routine to end only upon demand (pressing a certain key), However, pschopy doesn’t allow me to leave the ‘‘duration’’ as blank, and I get the following message: File "C:\Users\Usuario\Desktop\PsychoPy2\lib\site-packages\psychopy\experiment\components\sound\__init__.py", line 65, in writ…

Thank you very much, @dvbridges

hi @dcbridges, I am using version 1.90.1 and I just encountered this exact bug. The fix outlined in the previous post worked ( Problem with the offset of a sound component worked), but the bug is still clearly there in version 1.90.1. Any ideas? Also as a note, the sound components are still not p…

Hi @rosem09 , these bugs are fixed in recent releases of PsychoPy. I think the ValueError you are seeing relates to a mismatch in array sizes resulting from PsychoPY attempting to append a mono track to a stereo track. In Psychopy 3, we added a preference to “Force stereo”, which should fix your issu…

Hi @dvbridges . Thanks for your quick response. So before I saw your response, we realized we were using a stereo track and figured Psychopy 1.90.1 could only read mono tracks. We thus changed all of our tracks from stereo to mono and the experiment plays with the appropriate sounds and theoreticall…

Thanks, you can amend your code so that it is all surrounded by backticks? This will help us to read your code and offer suggestions to fix. If you are only using Builder then I suggest you update to Psychopy 3.

Okay here it is. As a note, this was created in builder (this is my first block of my experiment out of 5 plus blocks). I decided to use version 1.90.1 as I was told this version was the most secure (although at that time the person did not know I would be using audio files). Although this simple bl…

Well Builder is very flexible and has the code component should you need some custom functionality. This would be an easier introduction to coding for experiments. So, with your experiment, what error are you receiving when the duration of your sound is not specified?

Yes I should have clarified that I plan on using Builder to introduce myself to coding for experiments. In the first block of my experiment, I have two sound components in each trial (one Question sound and one Answer sound). Therefore, the first sound component does have a stop duration time so th…

Ok, well its the same problem as above that has been fixed. You could amend line 65 of the code so that the conditional only takes place if the init['stopVal'] is not None, as was shown in the link. However, you could also use the most recent Psychopy 3 with the fix in place. Is that an option?

Doesn't accept blank duration

Hi @pasoneto, this problem was answered in this post.. However, you could also update your version of PsychoPy to 1.90.1, as this has the fix included.
