Hello everyone! Could you please help?
For the test phase of my experiment, participants are shown two objects on the screen whilst hearing a word. They then have to match the correct object to the word they’ve heard. When running the test phase of the experiment I get this error, which I assume has to do with the sampling frequency of sound files in the conditions file. Could you please explain the error in the message and how to fix it using the builder? For reference, I am using Psychopy3 (version 1.85.3b-win32) on windows 10.
I highly appreciate your help.
