I hope this question is appropriate for this forum, and that you can possibly help lead me in the right direction. I'm using the warbleR package in R and I'm getting an error in my coding in the first steps of the analysis. I'm trying to filter my recordings in the coding, and I'm getting a specific error:

I tried to subset the data with only two or three .wav files, but I get the same error. Any guidance is greatly appreciated, thanks SO MUCH!
I'm attaching three of the .wav files in case one of them doesn't work for whatever reason! These are from xeno-canto though, they're not files from my Audiomoths that were deployed. In the above code, I'm trying to filter the .wav files based on an example here (https://rpubs.com/marcelo-araya-salas/110155).
Thanks so much!
On my system I am able use WarbleR and your code to process .wav files generated by an AudioMoth, so it it's unlikely that there is a systematic problem.
Can you post one of the files that are causing problems, and I will check it on my system? That way we will know if it's a problem with the files or with your R installation.
