Python script.
Uses FFMPEG to calculate loudness (based on LUFS) of tracks.
Writes the loudness information back to either replay gain (mp3, m4a) RBU loudness (opus) or opus loudness headers (opus.)
Opus loudness header does not show up in tag editors but it is mandatory for opus decoders to respect it.
