Discussions are often to scan library for -18 LUFS or -23 LUFS. While some like to aim for -14 LUFS.

If one could scan and tag library for the often used EBU R128/ITU BS.1770 standard (-18 LUFS).
But then be able to adjust to other targets from LMS Replay Gain settings would be a nice feature.

Or if someone already have scanned for -23 LUFS but then figure out thay want to add 5 LUFS for -18 LUFS target without having to rescan and tag 50k files.

If someone know if this already can be done with some file editing please let us know

thans!
