Quicker way of syncing sound?

When I have sync problems I normally demux, open the file in GoldWave, add a silence at the beginning of say a second, save as wav, encode to MP2, remux, and test. If the sound is still out of sync, I open the wav file again and add a pasue of half a second, or delete half a second from the beginning, and repeat the process. This takes a VERY long time and I was wondering if there's any way this process could be simplified?? Like a program that delays the audio or the video a set amount of time before playing so I can find out how far out the sound is?? :( :? :?: Hope there's an easier way to do this...

@pyRoMaNiA,

I add a filter called AVSMON to my script and use VirtualDub to
preview the video. AVSMON has an audio sync feature allowing you
to dynamically change the sync rate between audio and video. This
will allow you to get the correct sync much quicker. Give it a try :D
Check doom9.net for this filter.

Looks good but both the audio and video skip, making it hard to find the right delay...is there any way to fix this? All I have in my script is:

Code:

LoadPlugin("C:\...\MPEG2Dec.dll")

LoadPlugin("C:\...\avsmon.dll")

AudioDub(MPEG2Source("C:\...\video.d2v"),WavSource("C:\...\audio.wav"))

MonitorFilter()

Never mind, played it in WMP instead and it works fine, thanks for the help! :)
