The size of the sound file doesnt make a difference and the delays seem to be the case both for very short sounds (10ms) and longer ones (250ms). Unfortunately that might mean you can’t use dual independent displays for vision science studies until Microsoft fix it. The sounds are played with a delay of 100ms-200ms after the trigger and the difference between consecutive sounds onsets is not half a second. turning off extended desktop) until it works. revert the update) until a fix is listed on the status of the gamma bugĪltering your monitor settings in Windows (e.g. Team can do until Microsoft fixes the underlying bug. If you do need gamma correction then there isn’t much that the PsychoPy ® (rather than ‘abort’) and then your experiment will still at least run, 3) I have Piglet and Pyo installed and have uninstalled and reinstalled both. 2) I have tried to play simple audio files and those won't play the sound either.
So there is nothing wrong with the sound of the movie files. To the preferences and set the defaultGammaFailPolicy to be be ‘warn’ Here are a couple of things I have already tried: 1) The movies do play sound when I run them in QuickTime or VLC player. If you don’t need gamma correction then, as of PsychoPy ® 3.2.4, you can go This only occurs in certain scenarios, like when the screen orientation is in portrait, or when it is extended onto a second monitor, but it does affect all versions of PsychoPy.įor the Windows bug the workarounds are as follows: 6 s) - stimulus 2 But if the user responds to stimulus-1 at 1. So, the task is initialized as: stimulus 1 ( 4 s) - jitter (e.g. In Windows release 1903 Microsoft added a bug that prevents getting/setting the gamma ramp. Im locking the stimuli presentation to the 1s TR of the scanner so Im curious how I can round up the jitter time to the nearest second. Paste the following into that window (Ctrl-V doesn’t work in Cmd.exe but you can right-click and select Paste):
Reinstalling the application may fix the problem”? If so that indicates you need to update your. At the receiving end, the packets are de-encapsulated and converted back to an. To better describe this, consider a telephone call: voice is converted to digital bits (1’s and 0’s) and is encapsulated and sent across the network from source to destination. Windows users (starting from the Command Prompt):ĭid you get an error message that “This application failed to start because the application configuration is incorrect. In simple terms, jitter can be described as the varied delay between received packets.
The way to get that message depends on the platform (see below). If resetting the preferences files doesn’t help then we need to get to an error message in order to work out why the application isn’t starting. To fix that see Cleaning preferences and app data, below. Project description Release history Download files Project links. Newer version available (2022.1.2) Released: Psychology experiment software in Python.
What this means is that an error has occurred during startup itself.Ĭommonly, the problem is that a preferences file is somehow corrupt. PsychoPy 3.2.4 pip install PsychoP圓.2.4 Copy PIP instructions. You may find that you try to launch the PsychoPy ® application, the splash screen appears and then goes away and nothing more happens.
