ecasound defaults to stereo objects. You can set the default audio
format in your ecasoundrc if you so desire. Or specify it for each
output file something like this:

ecasound -i:somemonoin -f:24,1,48000 -o:somemonoout

If your chain contains a stereo effect you might want to combine the two
channels with -erm:1, or not.

(somehow I think I might be wrong about this ... Kai will correct me if
I am, I'm sure.)

Not sure about this one. What if you put the -el: arguments in ""s?
