Use second Audio track from MKV source?

[JackSnap]

Hi,

I have a MKV file with 2 audio tracks, which im trying to convert to WMV.

Im using windows media encoder with AVI synth and makeavis.
I wish to have only the second audio track in the WMV, how can I tell avisynth to do this as currently it just picks the 1st as default.

im using the directshowsource in the avs file currently.
but i cant seem to find how to pick the second track could someone point me in the right direction.

Many thanks

open your mkv file with mmg.exe (from mkvtoolnix) and remux into a new mkv selecting only wanted audio track

OR

using ffmpegsource you can specify the atrack to use (search for ffmpegsource plugin)

Thanks again!

I never feed audio streams to avisynth at all. In my opinion they should be processed separately from video and then muxed as you please.
