Presenting pairs of auditory stimuli - second stimulus not appearing

Hello! Couple of things:

  1. Is this following on from this study?
  2. Is there a reason you cannot use a single sound file that contains both tones?
  3. If you know the onset and duration of the sound the following should do the trick:

Begin Routine:

tone.playing = False
interval = 1#desired interval in seconds
if t >= toneOffset + interval and not tone.playing:# where offset if your known offset time and t is the ongoing time in this routine
    tone.playing = True
    tone.play()

That looks pretty similar to what you have tried though? Perhaps you could please share the file you are working ok?

Thanks!
