sync a foreign audio to 1080p in mkv

[loa-ash]

Hi, I'd like to know if there are other solutions to sync foreign audio to a movie 1080p in mkv.. I usually load mkv in adobe audition with ffdshow VC-1 active then, I load my foreign audio as second track and then I apply silence ad so on... but audition with 1080p is a little ram-hungry, there are others way to mux 1080p with foreign audio languages?
I've just muxed cloverfiled 1080p with italian audio from a dvdrip, and I was lucky beacuse I've add only 1s of silence at start of the movie and nothing else... sometimes the silences are in middle of the movie so is very hard with audition because is very slowly also in my core2 duo.

thanks in advance.

Try mkvmerge, it can apply audio delay, and is very quick (as fast as the slowest drive you are working from anyway) search google for mkvtoolnix.

Also AVIDemux can output mkv, so would be very useful aswell, as it has the ability to preview before you save the video.
