![]() ![]() This worked well, but my supervisor wants Psychopy to generate the number randomly and internally, to save time on our end during data collection. Following those instructions, I was able to do this by having a “group” field at the beginning of the experiment, then manually typing in a number 1-4 at the beginning of the experiment, and assigning a file using: I have four conditions files, named file1, file2, etc. sound.Sound () will then refer to one of the following backends: SoundPTB. You can select which will be used via the audioLib preference. PsychoPy currently supports a choice of sound engines: PTB, pyo, sounddevice or pygame. My current strategy is inspired by the advice about counterbalancing in another Psychopy article. Audio playback is handled by the Sound class. I suspect I misused this function but have no idea how to fix it.I have four stimulus files for a counterbalanced set of trials, and I need Psychopy to randomly select one file to use without cycling through all four, as would happen in a loop.
