hi Clayton,

I understand... rules are rules and if I've broken any, I apologize to

thanks a lot for the help, the code has now read the file with the
exclamation mark no problems!

only when recording the file he was converting all to 48000kHz sample rate,
but I made a change in the recording code line and now everything is ok!

Here's the change I made in the file's recording line:

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
-c:a libmp3lame -b:a %%B "..\Áudios LUFS ORI\!filename!_LUFS_CONVERTED.mp3"

FOR /F "tokens=1,2 delims=," %%B IN ('ffprobe -v 0 -show_entries
stream^=bit_rate^,sample_rate -of csv^=p^=0 "!filename!.mp3"') DO ffmpeg
-hide_banner -i "!filename!.mp3" -af
-c:a libmp3lame -b:a %%B -ar:a %%C "..\Áudios LUFS

thank you very much,
