Hello everyone. I’m trying to build an experiment(a verbal fluency task) that records the verbal responses of participants in 4 trials, for 60 seconds in each trial. The problem is, the experiment crashes before starting& I keep getting errors when I add the microphone to the experiment, but the experiment works fine when all microphone components are removed.
And an interesting observation, when I add only 1 microphone I can run the experiment for only the first trial(which is the one that includes the microphone), but when that trial ends, the experiment crashes & I get a somewhat different error.I tried playing with the properties of microphone component, such as sample rate(Hz), max recording size, etc., but none of them worked.
I’ve added the both errors(1 microphone & 4 microphones) below. Any help would be appreciated. Thank you.
This is the error I get when I run the experiment with only 1 microphone component added.:
