> 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
ILRA=%%b)
@FOR /F "tokens=3" %%b IN ('FINDSTR /C:"Input Threshold" "%%~na.log"') DO
(SET IT=%%b)
@FOR /F "tokens=3" %%b IN ('FINDSTR /C:"Target Offset" "%%~na.log"') DO
(SET TO=%%b)
DEL "%%~na.log"
SETLOCAL ENABLEDELAYEDEXPANSION
REM ECHO !II! Input Integrated

FOR /F "tokens=1,2 delims=," %%b IN ('ffprobe -v 0 -select_streams a
-show_entries "stream=bit_rate,sample_rate" -of "csv=p=0"
"!filename!.mp3"') DO (
ffmpeg -hide_banner *-report file=test.log:level=16* -i "!filename!.mp3"
-af
"loudnorm=linear=true:I=!_vLUF!:LRA=11:tp=!_vPEAK!:measured_I=!II!:measured_LRA=!ILRA!:measured_tp=!ITP!:measured_thresh=!IT!:offset=!TO!:print_format=summary"
-c:v copy -id3v2_version 3 -metadata:s:v title="Album cover" -metadata:s:v
comment="Cover (front)" -acodec mp3 -b:a %%c -ar:a %%b
"C:\Users\%username%\Desktop\Normalizando_lufs\!filename!.mp3"
)
ENDLOCAL
)
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.
