I'm trying to normalize (and or compress) around 100 .ogg files which have audio level really too low.
I know that by hand I can use Audacity ... but that will be too much clicks! Instead I was looking for a tool which can be used in a small script (or with --recursive).
Just tried to look in man oggenc
, man ffmpeg
, with no success yet...
Thanks!
-a -15dBFS
. With that option, I don't hear quality degradation.
