I just noticed that and at a first glance it looks weird to me.

I've encoded 11 FLAC files with FLAC Frontend. I've tagged them (without album cover), but I kept a copy of the untagged files.
When I compare their size, the tagged files and the non-tagged files have the exactly same size (in bytes).
(This changes of course if I add the album cover to the files.)

So why is that that add data to the file doesn't seem to make the file bigger ?
I guess I've used the standard tag files and maybe they have their place reserved even when they are empty ? Or something like that ?

Thank you for the info.

FLAC adds 8 KiB of padding by default when encoding files. That padding space allows for subsequent metadata alteration without changing the file size and without having to rewrite the file entirely.

See my profile for measurements, tools and recommendations.
