Deleting audio tracks from several multichannel wav files

I have a bunch of multichannel wav files that have redundant tracks that I’d like to remove (the removed tracks are the same in each one). I’d like to delete everything but tracks 3 and 4 in all of them and export them as stereo wav files. How do I do this?

How big is the “bunch”?
How many channels in the WAV files?

Do you mean that you want to do this as a batch process, or do you just need to know how to do it manually?

There’s dozens of files with 14 channels.

Do you mean that you want to do this as a batch process, or do you just need to know how to do it manually?

Indeed, as a batch process. I only now noticed I left this up for interpretation in my initial post.

You can do that with a macro (see: https://manual.audacityteam.org/man/macros.html)
These are the commands that you need:

SelectAll:
SelectTracks:Mode="Remove" Track="2" TrackCount="2"
RemoveTracks:
SelectTracks:Mode="Set" Track="0" TrackCount="1"
PanLeft:
SelectTracks:Mode="Set" Track="1" TrackCount="1"
PanRight:
SelectAll:
MixAndRender:
