Hello,

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.
