Background music in different loops

Coding
1

Hello guys!

I’m using psychopy version 2021.2.3 and I’m trying to put some random background music, in ten different routines to play continuously for 30 seconds while a block of ten words is presented on the screen, in which each word is presented at random, for 3 seconds.

I tried using an excel file, to select random songs, but it didn’t work, so I used the code component in each loop with the following code. However, it only works in the first loop, in the others the background music does not play.

Insert a code component into the routine where the sound will be played. On the “Start Experiment” tab, enter code like this to create the sound object in advance:

background_sound = sound.Sound(‘your_sound_file.wav’)
In the “Start routine” tab, put something like this, so that the sound starts playing, but only on the first iteration:

if your_loop_name.thisN == 0:
background_sound.play()

On the “End Routine” tab:

if your_loop_name.thisN == 10:
background_sound.stop()

Pardon my English. I’m new to Psychopy and I don’t understand programming, can anyone help me?

I understand you want to play music according to different conditions, so you can set it according to the conditions

What I do if I want to play a sound across multiple routines is.

Create the sound in a sound component, e.g. background_sound, with zero volume (online this only works if you use a sound file rather than a frequency) and the file set to update each repeat.

Then use the code you mentioned but you also need

background_sound.setVolume(1)

Hello, Wen!
Thank you for your comment. In block_A_1 the code and background music works perfectly, but when I configure block_A_2 with the same code, same audio excel file in trials to play a random song from the file, the background music does not play. I don’t know why. Thanks for your contribution!
Pardon my English. Do you know what I might be doing wrong in the experiment?

Hi! Thanks for your comment! I tried to apply your suggestion, but it still didn’t work.
