can mp3tag add ISRC, EAN/UPC & pre-emphasis in the tags?

hi
can mp3tag add ISRC, EAN/UPC & pre-emphasis ,Digital Copy Permitted ,4 Channel in the tags of audio files?

and is there a web service (tag source) like itunes ,discos or other web service that include these flags sometime present in the audio cd?

just for curiosity
thanks

See the help for supported fields: https://docs.mp3tag.de/mapping

hi

they are no preset
could be asked as a new features?
thanks

ISRC and TMED are included in the list.
You can create user-defined fields with any name.
What would be the standardized field name for the data you are looking for?
See e.g. for standard fields: http://id3.org/id3v2.3.0

hi
i would add to my songs , just because sometime i burn my audio on a cd
and i would like to create a cue-sheet with all these flags

about these flags even eac doesn't read all , i guess only cuetools cue ripper can read them all
but i don't want to make a collection of cue sheet files

may i ask you mp3tag can create a cue sheet ?

thanks Ohrenkino

see e.g. this thread: /t/11750/1

I am not sure if you got that right with the fields. The id3-org site shows you all the tag fields that are defined by the standard.
If the information you try to save is not covered by a tag field mentioned on the id3 org site then it is already covered by the option to create user-defined fields.
The "4 track" stuff is part of the TMED field - so that is already available in MP3tag.
