Split, join, create silence of an ac3 file

[phate89]

Hi all.. i usually work with ac3... i cut, insert silence and stuff like that to sync my audio with different video sources (muxing)..
I usually use audition to do that but it converts everytime loosing quality..
i know that it's possible to split and join ac3 files with some command line tool (besplit for example) so i thought to create my application.. i insert the points where i have to cut or insert silence and with my code i launch besplit that cut and join the file...
but there is one problem.. i don't know how to create ac3 silence files of fixed length and bitrate...
i try tosearch but i don't find anything.. you know some simple command line tool to do that?
thanks in advance

I try delaycut with command line but don't work with it ( idon't know why..should be supported... i pm the creator and i'm waiting an answer), silence doesn't work with command line since it's first update..
Eac3to i never tried it... you know if it adds the delay reencoding or not?
