Hi

I have searched the forum but have not found an answer.

 

When I have a number of tracks displayed in MP3TAG, I have a column for the track's length in hh:mm:ss format.

 

I wish to store that length in the appropriate ID3 TAG. There are a number of %length% fields in MP3TAG but, I have tried all sorts of manipulations and cannot get the track length to store in a tag. I am sure I am missing something. How does one store the track length in a TAG?

Hi

Please ignore my previous post about adding track time to the track Tag list. I finally found the function that allows me to do that.

 

For those wanting to do the same thing, or something similar, use MP3TAG Function TAG - TAG.  
The following is for storing the track length.

 

In the displayed dialog box:  
Field: Length  
Format: %\_length%

 

I tried other fields but the audio track I used as a test track did not have any other information.

As the length is already part of the header (and cannot be modified by MP3tag) I wonder what purpose a duplication of that information should serve.  
The proper fieldname is %\_length%

I am writing a [VB.NET](http://VB.NET) application where I am using a ID3V2 library that doesn't return header information. All information is accessed by TAGs. I could modify the source code to return the header information, but decided to use the library DLL as is. Note that I am not **_modifying_** the length but just want the TAG, TLEN, to be in the file. If you have a better way, please advise.
