Do you mean that your music is stored as normal audio files on a Synology, and that you're using php (via getID3) to populate a MariaDB with the track information, or are you writing from the database to your files? I've loaded up a MusicBrainz database dump into MariaDB before for cleaning up my existing tracks - writing via foobar - but I don't think I have a need to put it into a database - and don't want covincing that I do :-)

Just so I'm clear, are you asking for a tool to extract the dynamic range tags, or are you wanting a Dynamic range library to use?
If the latter, I'm not aware of a library for this, but you could ask on the hydrogenaudio forums (or the foobar forum within that).
