Wrong audio length, mp3 to aac

[Tom Dozer]

I have some meditation files with long silence.  When I convert these from mp3 to aac, the Audio Length parameter is wrong, but the audio is all converted correctly.  Does anyone know a work around for this?  For example, the file is 2:15, but the Audio Length parameter is 1:03.

I found a solution.  The error occurs when I use the setting option VBR 50.  If I convert the file from mp3 to aac using the option ABR 128, the length is a little longer than the mp3, but that is OK.  Then I convert the file, aac to aac VBR 50.  

If anyone knows a better work around, please speak up.

I think the nature of the problem is that conversion does not work properly when the is absolute silence.  I added a very low level of noise, and it works better.  It gives a length that is longer than the original audio.
