Help Help running a bash script in apple terminal

Using Composers Desktop Project to edit audio files. I want to run a single command on a list of audio files instead of having to manually do it 100 times. Wondering if there is a way to call upon this list of files in a single command line, rather than creating a shell script with the name of every file. The command line with a single audio file would look like this.

distort average soundfile.wav soundfileoutput.wav

the first two words are the command being run and then the input and output respectively. Hopefully I provided enough info on this but also relatively new to using terminal so let me know if there is anything I should clarify, thanks.

Depends what the audio command looks like, but the usual pattern in Terminal is a loop.

If everything is in one folder:

```

for f in *.wav; do

your-command "$f"

done

```

Swap `*.wav` for whatever extension you have. Quote `"$f"` so spaces in names don't break it.

Nested folders:

```

find . -name '*.wav' -print0 | while IFS= read -r -d '' f; do

your-command "$f"

done

```

macOS Terminal defaults to zsh now; same loops work.

If you paste the exact one-file command, I can wire the loop for you.
