"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

What language did you want to use?
As far as I know, CD Audio tracks do *not* hold such information.

The software systems you mentioned above use database lookup over the internet to retrieve such information based on some unique CD identifier.

Hello Mr Nayer ,
                       I have got some little information about RIFF files on Audio CD.Which have this information.And some artical says this information is stored in start bits of tracks.But i dont know how to access these start bits.And how to read RIFF File  from Audio CD.
When we play any Audio CD with Windows Media Player.It provides this information(Title,Artist,Album,Track,SongYear).

From Where media Player get this Information.

Thx for Reply me .

Windows Media player pulls its information from the internet (www.windowsmedia.com)

Now how it figures out what you are listening to is tricky, since CD's do NOT have any useful serial numbers associated
with them (Exception: Some CD's esp by Sony use CD-Text subchannel data, your on your own there...)

Most players use the CDDB service by Calculating the TOC length, number of tracks, length per track, and
fudging that together to get a unique ID number (the DiscID), they can then access the net to pull
information from the service

I don't know if this helps or not.  Oh, here's an excellent article using VB to calculate the DiscID and pull
track info from freedb.org


The key elements are

1) Get the CD TOC using ASPI calls
http://www.hochfeiler.it/alvise/aspi_VB.htm provides a wrapper dll which you might not need in VB.Net since the calling convention is now changed.
2) Calculate the DiscID
Steve's snippet shows how this is done. for FreeDB
3) Make a request to freedb.org for the track information


PS: These folks have a nice intro to CD-Text
