I think the current convention by users is to store lyrics in the LYRICS tag. cover art is not part of the tags, it will go in the PICTURE metadata block in upcoming FLAC 1.1.3: http://flac.cvs.sourceforge.net/*checkout*/flac/flac/doc/html/changelog.html Josh ____________________________________________________________________________________ Sponsored Link Free Uniden 5.8GHz Phone System with Packet8 Internet Phone Service http://www.getpacket8.net/yahoo2

Is the 0x05 "leaflet page" picture type what you'd use for scanned liner notes? We suggest people who want to embed artwork in ogg do so as a parallel stream multiplexed with the audio data, using http://wiki.xiph.org/OggMNG. However, there's no convention for doing an entire album in an ogg file the way there is with flac, so we generally recommend people just put all the tracks in a directory along with the artwork as separate files and use the freedesktop.org .desktop file to point to the cover. -r

I'm always having a special look for track 01 index 00 in EAC.... but if you use index-based extraction you'll get one file for each range.>> btw: This is not the right place to ask,.. but is it planned to add a >> standard to ogg (and thus flac) like ogg comments,.. but for >> additional stuff like lyrics,.. or CD-cover art and so on? >> > FLAC uses the same tag standard as vorbis. ogg has no tag standard. > the vorbis standard does not mandate any tags, but has some > recommendations.There is one thing I forgot to ask last time.... when using that cue feature from flag,.. is it possible to store different tags (title, composer, etc) for each range? And if so how do I specify this on the command line?> I think the current convention by users is to > store lyrics in the LYRICS tag. cover art is not part of the tags, > it will go in the PICTURE metadata block in upcoming FLAC 1.1.3: > http://flac.cvs.sourceforge.net/*checkout*/flac/flac/doc/html/changelog.html >I assume that this could be added later via metaflac to already encoded files? btw: are there any other changes (e.g. in encoding strenght or so) that makes it worth waiting for 1.1.3?
