\section{\label{ref:SupportedMetadata}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 \emph{one} tag type supported for each file
|
|
extension.}
