Always start by posting the complete ffmpeg command and unedited output,

My bat file will read several mp3 audios in a folder and normalize the
LUFS, saving the files in another folder. I wanted to save loglevel 16 of
these files in another folder on my desktop called Logs
My code:
md "C:\Users\%username%\Desktop\Normalizando_lufs"
pushd "%Userprofile%\Desktop\µudios LUFS"
FOR /F "delims=" %%a in ('where .:*.mp3 ^|findstr /vi "_LOUDNORM _EBU"')
DO (
SET "filename=%%~na"
ffmpeg -hide_banner -i "%%a" -af "[0:a]loudnorm=print_format=summary" -f
null NUL 2> "%%~na.log"
@FOR /F "tokens=3" %%b IN ('FINDSTR /C:"Input Integrated" "%%~na.log"')
DO (SET II=%%b)
@FOR /F "tokens=4" %%b IN ('FINDSTR /C:"Input True Peak" "%%~na.log"') DO
(SET ITP=%%b)
@FOR /F "tokens=3" %%b IN ('FINDSTR /C:"Input LRA" "%%~na.log"') DO (SET

Using the -report command, the bat is canceled and a log is generated in
the folder in the current directory, see the -report command message in the
log:
Successfully opened the file.
Parsing a group of options: output url file=test.log:level=16.
Successfully parsed a group of options.
Opening an output file: file=test.log:level=16.
[NULL @ 000001bcd0518640] Unable to find a suitable output format for

file=test.log:level=16: Invalid argument
thanks

*-report file=test.log:level=16* the character * on the commandline
causes ffmpeg to look at this as a outputfile specification to put
decoded results in, as nothing is specified about how to decode it it
tries to guess what codecs to use on the extension. Naturally this does
not work. Easiest way to get your desired result is to set the logfile
creation as an environment variable in the beginning of your script your
script and remove it from the ffmpeg commandline like this:
FFREPORT=file=test.log:level=16 md
"C:\Users\%username%\Desktop\Normalizando_lufs"
pushd "%Userprofile%\Desktop\µudios LUFS"
FOR /F "delims=" %%a in ('where .:*.mp3 ^|findstr /vi "_LOUDNORM _EBU"')
DO (
SET "filename=%%~na"
ffmpeg -hide_banner -i "%%a" -af "[0:a]loudnorm=print_format=summary" -f
