Vorbis comment is a metadata - Container of Xiph.Org Foundation for storing printed text. This allows z. B. Metadata can be added to music files that contain information about the respective piece of music. It is used with Xiph's free codecs Vorbis , FLAC and Speex , comparable to ID3 tags for MP3 files.
Like APEv2 , with Vorbis comment , in contrast to ID3, you can create not only predefined, but also freely defined fields for storing information.
A Vorbis tag consists of a list of fields in the format
Feldname=Daten. The field name can consist of printable ASCII characters (0x20 (space) to 0x7D ('}'); except for 0x3D ('=') and 0x7E ('~')). The system does not differentiate between upper and lower case, so title and TITLE designate the same field. The number of fields and their lengths are limited to 4,294,967,295 (the largest value of a 32- bit - integer ), but most editing programs have tighter limits.
Field names and the format of the values are not required. Field names can also be assigned more than once, which means that several values are possible for a field name (as in id3v2.4 for mp3 files). It makes sense z. B. in a work in the performance of which several performers were involved.
The specification defines several example field names such as title (title), artist (artist), album and tracknumber (song number), in addition, most applications offer de facto standards such as discnumber (CD number) and fields for replay -Gain information.
Saving binary data in Vorbis comment is not intended. The metadata container was designed to be part of a respective container format. It is intended to store additional binary data directly in this respective container.
