Converting .itdb files to .mp3 audio format.
As far as we know, converting iTunes Database Files directly to MP3 Audio Files (.itdb to .mp3 conversion) is not possible, since ITDB databases do not contain any multimedia data.
We are not aware of any available audio editing software or (online) conversion tool capable of directly converting ITDB to MP3.
In a word, direct itdb to mp3 conversion is not possible.
So don't expect any so-called itdb to mp3 converter or itdb to mp3 free online conversion tool available.
The database currently does not contain any itdb software converter.
