Microphone recording that starts at the beginning of a routine, and ends on button press

What did you try to make it work?:
I selected the microphone array

What specifically went wrong when you tried that?:
I get the following error message. I tried using the default microphone settings in the component, and got the following. I also tried using other settings but got the same message.

I also tried using the code import psychopy.sound.microphone.Microphone as Microphone, by following the overview here: Microphone - for recording sound — PsychoPy v2022.2.4, however in that case I got the error message. However, I received the message
ModuleNotFoundError: No module named ‘psychopy.sound.microphone.Microphone’; ‘psychopy.sound.microphone’ is not a package
This might be because I haven’t installed psychtoolbox, but since psychtoolbox runs in MATLAB I don’t see the connection.

As an update, if I try to run the microphone demo in psychopy 2022.2.4, I get the following error message:

Hello,

it seems as if you selected sampling parameters, most likely sampling frequency, which are not supported by your device and the chosen sound-library

Best wishes Jens

Thanks Jens,

I read the error message before I sent it to you - I thought you might have some more information or tips. This seems like it might be a common issue since it is quite basic.

I tried all the different settings for sampling frequency but still received the same message.
My channel count is stereo, and the audio sample format is set to default.
I have no idea why the error is thrown.
I can record in MATLAB using any arbitrary sampling frequency.
I can record in e.g., audacity with no issues at all using different sampling frequencies.

I then used the code used in the microphone component manually. It is described here: Microphone - for recording sound — PsychoPy v2022.2.4) is possible, but that link contains some errors. It does not seem to require Psychtoolbox, contrary to what it says. Also, using “bufferSecs” as written in the example will throw an error. The argument is streamBufferSecs as you can see in the description of parameters.

I used the code:
mic = sound.microphone.Microphone(streamBufferSecs =10,
device=None, channels=None,
sampleRateHz=44100)

I have no idea why this works but it seems to work. The microphone component itself does not work however.

Hello, I’ve met the same problem…No idea why it always shows this type of error how I change the settings
