I'm trying to convert mp3 files to ogg, but I found a problem: most or all of the metadata is disappearing after the conversion. Is there a way to keep it?
The userfriendly program soundconverter (Gnome Sound Converter) retains at least artist, title, album, comment and year(*) when converting to ogg.
The command line program sox retains at least artist, title, album and year(*), but apparently not comment.
sox xxx.mp3 xxx.ogg
(*) some programs may disagree if year is release time tag or recording time tag.
