I used Psychopy2 to build my experiment (from the builder with lots of additional code components), and the sounds played per…

If you look at the experiment in Coder view, what are the parameters when the noise component is created? It should look something like this: noise = visual.NoiseStim( win=win, name='noise',units='pix', noiseImage='testImg.jpg…

Sounds like the sample rate is not be correctly set for the audio. However, I’m not quite sure what’s happening here, need to look into it.
