> You said:
> *-report file=test.log:level=16* the character * on the commandline

> 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

>   1.1 - When I use the command FFREPORT:
>         FFREPORT=file=test.log:level=16 md
> "C:\Users\%username%\Desktop\Normalizando_lufs" ffmpeg -hide_banner -i
> "!filename!.mp3"
>
>         Show the error:
>         'FFREPORT' is not recognized as an internal command
>         or external, an operable program or a batch file.

>         PS 1: in this case, so that the FFREPORT command does not show the
> above error, I have to put SET before it, eg:
>         SET FFREPORT=file=test.log:level=16 md
> "C:\Users\%username%\Desktop\Normalizando_lufs" ffmpeg -hide_banner -i
> "!filename!.mp3"

>         then it shows the error:
>         [NULL @ 00000268a5249100] Unable to find a suitable output format
> for 'FFREPORT=file=test.log:level=16'
>         FFREPORT=file=test.log:level=16: Invalid argument
>
>   1.2 - Note, in my code, that the loudnorm command is inside a FOR loop.
