Thank you, you seem very knowledgeable in this area...
Well, it sounds advanced... Yes, its a stereo alright, that much
I know.
I tried this but it sounds so bad I even had to put a warning in
a comment:
# first do:
# $ pip install ffmpeg-normalize
#
# but... don't use, at least not with music, sounds terrible :(
get-mp3-normalized () {
local -a files
files=($@)
local dB=-10 # db/LUFS
for f in $files; do
ffmpeg-normalize -f -c:a libmp3lame -t $dB -ext mp3 $f
done
