How to use Sox for all files in a directory

Question

How do I change the sample rate for every file in the folder?

The following code converts the files, but it erases the file. After this command, every wav file is empty.

for i in wav/*.wav; do
    sox -r 8000 -e unsigned -b 16 -c 1 "$i" "$i"
done

How do I run the code to every file in the directory?

I don't know `sox`, but I'm guessing you're trying to write to the same file you're reading, and that truncates the file - see [this Q&A](https://stackoverflow.com/q/6696842/3266847). — Benjamin W., Aug 19 '20 at 03:31

Something like:

for i in wav/*.wav; do
    sox -r 8000 -e unsigned -b 16 -c 1 "$i" "$i_modified"
done
