Two options:

ecasound -f:32,12,44100 -i alsa,hw:0 -o foo.wav

... will record 12ch from the ALSA device. If you want to route the
individual channels to different files, I recommend using JACK, and then:

ecasound -f:32,1,44100 \
         -a:1 -i jack -o foo1.wav \
         -a:2 -i jack -o foo2.wav \
         ... \
         -a:12 -i jack -o foo12.wav
