I have been manually editing downloaded MP3 tags
in XP file Explorer and Winamp .

Now I need a BCB tool to read and write MP3 tags .

Thanks , Jim D

How do you mean "read and write" MP3 tags? To automatically get CD track
information from CDDB? or just open them to display/edit them in your App?

Also what version of the ID3 tag are you using? Check out the ID3Tag
website (Sorry don't remember it) for information on the format of tag.
The original version was the last 128 bytes of the mp3 file by building
a structure then reading the last 128 bytes into it, you get the
information. However the standard has grown it include a lot more
information. I do believe that the website also has source code and a
library for doing what you are asking about.

Good Luck.

Please specify "website" .
XP MP3 files downloaded from abs.mp3.19?0s
commonly have both ID3v1 & ID3v2 tags .
I need BCB object to edit said tags in disk files .

Also need docs on internet fetching tag info given
Artist & Title (not Album_Title) .

I have written a program to scan .mp3 files to extract information.
I found it took quite a while because of the things you have to take into account like
normal data frames, ID3v1 & ID3v2 Tags and then the variable bit rate headers/frames (xing & vbri).
I have not considered updating the Tags yet although ID3v1 would be easy enough (last 128 bytes) but
ID3v2 is embeded at the front of the file.

Any way here are some links which might help (In section 5 of the first web link page there are more web
links)

I was looking at the documentation from freedb awhile ago, and seem to
remember that their is a way to get information for just a single track.
I'm not sure if you needed the full CD to calculate the the information
to retrieve it thou.

--------------- PAGING TONY BENHAM --------------------------------
(1) Does your program read both ID3v1 & ID3v2 tags ?

(2) Can I use in XP with BCB6 ?
To rename files from tags

Tony , kindly post program info to this thread ,
or email jim46dd_AT_verizon_DOT_net

----------------------------------------------------------------------
Still missing dark db to fetch tags given only Artist & Title
Or pay $ for nicely tagged mp3 from website ?

For each mp3 filename in explorer.exe selected file list :
read A&T | if blank ? parse filename | seek A&T in db | write tags :
Year Picture Comment Genre
Album TrackNum Duration BPM
wwwArtist wwwRadioPage wwwUser InitialKey
