Metadata or "data about data" is information about an object and collected as specified in a schema. There are several schema in use for audio-visual work each specifying many different elements.
Metadata elements collected need to be selected to suit the eventual users and be manageable. The broadcaster requires different data to the academic or library administrator.
Automation greatly assists with some tasks
When tapes and discs are digitised metadata comes from several sources eg.
The BWF allows embedding of data eg. ISRC, Originator details, encoding history etc but this is not standardised and data may be ignored or even deleted by other software applications.
Before work commences we will arrange what data we should collect and how it is to be submitted.
If you prefer we can supply a default list of elements from the AES, EBU or LOC schema.
MP3 metadata frames are defined in ID3v2, an informal standard. Users can define their own frames, if needed. The present list of frames is here.
MP3, CBR, 48kHz, bitrate to suit
