How to present simultaneously two sounds

If this template helps then use it. If not then just delete and start from scratch.

What are you trying to achieve?: To simultaneously present two sounds, one from the left speaker and one from the right speaker- Preferably using the Builder.

What did you try to make it work?: I am using the Builder, but only one by one is played, while I need to play both stimuli at the same time

It’s not clear how you tried to implement it. What I have done in a similar case was that I used Audacity, an open-source software for audio processing. I used the panel slide of Audacity (as shown in the picture to create 2 sounds, one from Left (L) speaker and one from Right (R ) speaker. Then you go to Builder you make two separate sound components you attach the .wav files, you specify the time and there you go.

Thank you for your reply! I thought to do something similar, but how can you play two sounds component at the same time? In the builder I created two sounds stimuli (I attached a picture above) but only one at a time is being played.

You have to edit your sounds outside psychopy. At least, this was what I did and worked. Sound1 should be edited (e.g. in Audacity) to play only from the R speaker and Sound2 only from the L speaker. Otherwise, it’s quite obvious why only one sound is being played at a time.

I see, thank you for the clarification!
