B.2. Supported metadata tags
Rockbox supports different metadata formats. In general those tag formats are ID3
(v1.0, v1.1, v2.2, v2.3 and v2.4), APE (v1 and v2), Vorbis, MP4 and ASF. Few codecs
use codec specific tags, several codecs do not use any tags yet. The following table gives
an overview about what tag types rockbox supports for which audio file extension.
Note:
There is always only
one
tag type supported for each file extension.
