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

DelayCut can add silence. Apparently you can use a command line with it.

I tried but seems it doesn't work the command line.. with gui no problems.. i see also silence utility of the same author but it remove command line support for that.. any other solution?

Me? I keep as far away from CLI as I possibly can. The included doc has the instructions which I suppose you already read and tried. My suggestion is to PM the DelayCut author (jsoto) either here or at Doom9 and explain what you're trying to do.

I already wrote a pm.. but maybe you or someone else know other alternative tools

Audacity > Generate > Silence > insert length.
The project rate is shown/adjusted on the lower left of the window.
The bitrate can be selected by selecting Export, then options.

audacity like audition reencode the audio when it saves it.. exactly what i'm trying to avoid..
