Thanks for your quick reply. I am, in fact, not sure I got this line “In your sound compoenent, switch from specifying the sound file on every routine to instead be during the name of that static period.”
So, the “$sounds” value in the Sound subfield refer to the columns in my ‘conditions.xlsx’ file containing the names of individual .wav files. Are you suggesting doing something else? Sorry I am just a beginner user of PsychoPy.
