Hi

There are several components/code that allow you to read ID3 tags, but
they seem to either support only V1 or only V2, but not both. So I need
to know how to find out which version an existing MP3 file uses, so that
I can use the appropriate code.

A) How do I do this?
B) Does anyone know of a (free) component/free code that supports both
formats?

Regards

Peter

MP3 files can use BOTH versions. Many MP3 files, that have a v2 tag, also
have a v1 tag for backwards compatibility (for example that early versions
of WinAmp can still read the v1 tag). The v1 tag simply are some bytes at
the end of the file. The v2 tag is somewhere in the middle of the file (can
be anywhere, but is at the very beginning in most cases), is harder to
handle, but more flexible.
