How to simultaneously run two routines?

White space is important in Python so you need to do this so we can be sure to read your code properly:

Please surround python code with backticks

When you include python code on this forum please put triple “backticks” like this ``` on the line before and the line after your code. If you’ve done it correctly then your code will appear in a grey box with correct indentation like this (check the preview of your post on the right hand side before posting it) and other people will be better able to work out what might be right/wrong with your code. if myVal==True: break If you’ve already posted something that didn’t follow this rule th…

I’ve edited your post above, and if that code was pasted in correctly, then an issue is that you are re-setting the clock on the beginning of every iteration, rather than just at the start of the first iteration (when the sound file itself is played). i.e. with correct indentation, those two operations would be grouped together so that they are both conditional on this being the first iteration, like this:

# only at the beginning of the loop, both start a sound playing and
# start a clock to keep track of its progress:
if trial.thisN == 0:     
    background_sound.play()
    audio_clock = core.Clock()
