Hi people, I am planning to conduct a multisensory (audiovisual) research on Pavlovia and I learnt that there will be an inevitable asynchronization if doing so (https://psyarxiv.com/d6nu5/ — an article I refered to).
Since all my stimulus would be about 5 seconds long and this is a sophomore level project, there is no need to achieve a millisecond level precision, but I would like to know what are the things I could consider and improve, including hardware, coding tips, or any other potential solutions.
Also, does anyone know what does the “nan” mean here, is it a lack of data?
