I tried to convert some EEG CSV files from CSV to WAV, that only has a sampling rate of 256, and most of them work, with some sort of pulse sounds.
I used the coding steps as mentioned here: https://www.mathworks.com/matlabcentral/answers/471007-how-to-convert-csv-file-into-audio-file
Then, I viewed or edited them with Adobe Audition software. However, it seems like sometimes it doesn't work with no sounds.. Could someone please help explain what may be the issue?
I attach here the two files that work and don't work.
Could someone also help explain what it means when I get to the audiowrite step, it has the following warnings, what does it mean?
Warning: Data clipped when writing file.
> In audiowrite>clipInputData (line 470)
In audiowrite (line 241)
Thank you for all your help!

Data clipping happens when the audio data to write is not in the valid range depending on its type.
Refer the documentation link for audiowrite function to check the valid ranges for the audio data to write.
