I'm not sure you understand. I meant the strong / bold font layout, the two asterisks surrounding %G.

Try this:

@ECHO off
SET vluf=-10.0
SET vpeak=-0.0
FOR %%A IN (*.mp3) DO (
  SET "filename=%%~nA"
  ffmpeg -hide_banner -i "%%A" -af "loudnorm=I=-15:TP=-1.5:LRA=11: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"
  ECHO !II! is the Input Integrated
  ECHO !ITP! is the Input True Peak
  ECHO !ILRA! is the Input LRA
  ECHO !IT! is the Input Threshold
  ECHO !TO! is the Target Offset
  FOR /F "delims=" %%B IN ('ffprobe -v 0 -show_entries stream^=bit_rate -of default^=nk^=1:nw^=1 "!filename!.mp3"') DO ffmpeg -hide_banner -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:a libmp3lame -b:a %%B "..\Áudios LUFS ORI\!filename!_LUFS_CONVERTED.mp3"
