Error running mic response in Windows

Builder

OS : Win 10 Pro
PsychoPy version : 2021 2.3
Standard Standalone? (y/n) : y 64
What are you trying to achieve?: I want to add a double response: a button press that will be done by the experimenter (either pressing ‘c’ or ‘v’) and a verbal response recorded by microphone and given by the participant. I was wondering whether you could help me figure out the issue I have with the mic component.

What did you try to make it work?: So far I was able to make the experiment work without the microphone component but when I add it I run into errors. I have been reading some older topics in the forum but I have not been able to solve the issue. I have changed my preferences to PTB, pygame, pyo and sound device but it still does not work. I had problems before getting to run experiments with the PTB library. For me latency is important.

What specifically went wrong when you tried that?:

Hello,

you requested a sampling frequency that is not supported by your hard- and software. Try a sampling rate that your hardware is capable of.

Best wishes Jens

Thank you @JensBoelte , do you know where can I find such information? Because I did not change or choose the sample rate.

Hello Marc_CR

well, the microphone-component has a tab called hardware. There you can set the sampling rate.

Thank you @JensBoelte, I have checked and I have the same options than you.

error_psychopy_samplingrate_options
I have no choice for Hz if I need to record the voice.

Best,

Hello Mar_CR,

your screenshots are too small to read. You can record with any sampling rate you want. When recording voice you don’t need a sampling rate of over 16 kHz because the human voice spectrum goes from around 80 Hz to 12 kHz. So, voice is just a label here.

Simply choose a sampling frequency that matches your hardware.

Best wishes Jens

Hi @JensBoelte ,
Sorry for the quality of the screenshots and thank you for the rapid answers! I tried to change it to 8Hz and even change the audio library but I still have the same error.

Hello

read the error-message. You again selected a frequency that is not supported by our hardware and sound driver.
My reply was probably misleading you. I simply wanted to explain that the frequency range of 80 Hz to 12 kHz is the frequency range of the human voice. With a recording sampling frequency of 16 kHz you can record the whole spectrum of the human voice (well, not quite but that is another story).

You need to select a frequency that matches your hard- and software. So simply try out the higher frequency ranges.

Hi,

Sorry for all the messages and thank you for your explanations. I chose the lowest sampling rate possible from the options (8Hz) and it still says that it is not supported by my hardware and sound driver. How can I solve this problem if no Hz options seem to match my system?

Thank you in advance for you help and time

Hello,

simply select a higher one.

Best wishes Jens

@JensBoelte Thank you for your suggestion and sorry for the late reply. I have been trying several things, now with 48Hz it seems to work but the folder for the microphone files is empty.
