If you don't convert to mono, it will depend on the listening

-ea:-100 and -eac:-100,channel
Here's a simple example:
ecasound -a:1,2 -i track.wav \
-a:1 -o channel-1.wav \
-a:2 -o channel-2.wav -erc:2,1 -ea:-100
Now combine them with:
ecasound -a:1 -i channel-1.wav \
-a:2 -i channel-2.wav \
-f:16,1,44100 -a:1,2 -i track-mono.wav
And that's it, you'll only hear hard-panned signals in the resulting
