File type Text information frame.
The 'File type' frame indicates which type of audio this tag defines.
The following type and refinements are defined:
MPG | | MPEG Audio |
/1 | MPEG 1/2 layer I |
/2 | MPEG 1/2 layer II |
/3 | MPEG 1/2 layer III |
/2.5 | MPEG 2.5 |
/AAC | Advanced audio compression |
VQF | Transform-domain Weighted Interleave Vector Quantization |
PCM | Pulse Code Modulated audio |
but other types may be used, not for these types though. This is used
in a similar way to the predefined types in the "TMED" frame, but
without parentheses. If this frame is not present audio type is
assumed to be "MPG".
