Avisynth in Windows 7 64-bits

[carlmart]

What Avisynth version should I use within Windows 7 64-bit? Will all filters work?

Any version you want, but the 32 bit one has more filters than the 64bit one. You can only use filters built specifically for the avisynth version you are using(32 or 64 bit).

I personally mostly use 2.6MT 32 bit by SEt with win7 64bit since there are some filters I need that are not available for the 64bit version, but I also installed the 64bit one for tests and they work fine together(actually, you need to install a 32bit version to use the 64bit one, at least for the build I used)

Lately I'm mostly doing audio conversions from DTS to AC3 with AvsP, using NICDTS and NICAC3. Will they work in 64bit?

As far as I know, there are no 64bit version of the NICaudio Dlls but I might be wrong since I never needed them so I didn't search a lot.

Use the search function of the forum to see if you can find it or go with the 32bit version which is plenty(and more stable) if you're simply doing audio conversion.
