Feurio Questions & Answers - Questions on CD-TEXT:
Maximum size of CD-Text information?


Question: How large is CD-Text information allowed to be? Is there an upper limit for the length of a track title?

Answer: Usually you don't have to worry about this at all - there is enough memory available for CD-Text information.
Basically, the following applies: The length of the CD-Text information per track is not limited - if the information entered is longer than the display on the CD-Player, then the text is shown as a running display.
The overall length of all CD-Text information however is limited; but the limit is so high that it normally doesn't have any effect. With 30 tracks, for example, the average length of the information per track can almost be 100 characters - so this should really not cause any problems!

If you want to know the details:
A CD-Text "Block" may be made up of a maximum of 256 so-called "Packs".
4 packs are needed for internal purposes.
The other 252 packs can be used for CD-Text information.
Each pack contains 12 characters.
Thus a total of 3024 characters of CD-Text can be saved.
One character is needed as a separation character per track, thus with the maximum number of 99 tracks (+ 1 pseudo-track for the CD title), 2924 characters remain. If artist and title are entered for every track, 2 * 100 characters have to be subtracted, as artist and title are saved separately (so 2 separation characters per track are required), i.e. 2824 characters still remain - there are still 28 characters per track (for artist and title, i.e. e.g. 19 characters each for artist and title or any other distribution)!

With a "realistic" number of e.g. 30 tracks there are even 98.8 characters per track - more than enough - and because only the overall length counts, any individual track may be considerably longer if another is correspondingly shorter.
