auditory search task
I'm looking to implement an auditory version of the visual search task in the intermediate tutorial. I've searched on this forum, and it appears that I need to use the pyaudio or pygame python module to present sounds simultaneously. I modified some code that I found online that attempts to present sounds simultaneously; however, it needs to be modified so that sounds are presented at predetermined channels/locations and with little lag during presentation onsets. Additionally, I plan on presenting an additional, surprise sound during a randomly chosen trial so that it is played along with the target and distractor sounds. I want to collect measures like response time and accuracy to target sounds. I've uploaded the code that I have that attempts to present sounds simultaneously (warning it is very basic!). I also have a modified version of the visual search task (keyboard response time is limited and a surprise sound plays during on trial) that I can upload if needed. Any advice on how to proceed is greatly appreciated.

Hi,
Do you want to improve the timing accuracy of auditory stimulus?
You need to check your experimental settings carefully in terms of both software (program) and hardware (devices you use) because it's difficult to control it perfectly.
I don't mean it is impossible. Please see the discussion below.
