Hello all,
I am a seasoned psychology experimenter, but started using PsychoPy only a month ago.
My message is about microphone. I have noted a number of ‘mic’ issues in the forum, but nothing quite like the one I would like to share here.
Also, I have updated from 3.1.2 to 3.1.5 tody, as the mic seemed to be at stake there.
Thank you all in advance !

OS : macOS Mojave 10.14.5
PsychoPy version (e.g. 1.84.x): V.3.1.5
Standard Standalone? (y/n) If not then what?:
What are you trying to achieve?:
I am setting up an experiment in which participants name pictures. The mic is triggered with stimulus appearance and records what participants say for a fixed duration of 2sec.
I have noted that int the first few trials, an empty wave file of the right duration is generated. After a few trials (between 3 and 5 in various tests), the recording starts to work properly midway during the 2 sec window. From there on, all the trials (~15 in the test) are perfectly recorded.
What did you try to make it work?:
I do not seem to get any error message.
I have toggled Hardware/Audio Library between
[‘sounddevice’, ‘pyo’, ‘pygame’, ]
and
[‘pyo’]
I have also tried the demo voiceCapture, adding trials in the loop there.
What specifically went wrong when you tried that?:
Changing the audio library does not change the behavior.
The behavior is replicated with the demo file.
