Errors with open .wav file

Hi the community,

Operating System: Windows-10-10.0.18362-SP0
version: psychopy3
python 3.6

I am trying to create sound components with audio files. The .wav files are under the same parent folder as the project file. In the condition file, the relative path to each .wav file is given and the sound component path is set up with the column name.

What did you try to make it work?:
I have tried change the file name to .aiff and I am sure the path should have no errors. I also installed FFmpeg so that the .wav can be handled.

What specifically went wrong when you tried that?:

do you mind uploading the wav-file? There seems to be a format error.

Thanks for response and sorry for the delay. Sure here are some examples.

Hello littlethumb123

all your examples are mono 32 bit 24,000 Hz. You might want to try 16 bit, 44,1000 Hz instead.

Thank you. It works. Just in case other folks may have the same issues, Audacity can configure the sample rate and file format for this issue.
