Would that be something like (assuming .wav's are mono):

-a:t2 -i t2.wav -erc:1,2 -f:32,10,44100 -o alsa,hw:0
-a:t5 -i t5.wav -erc:1,5 -f:32,10,44100 -o alsa,hw:0

-a:t1 -f:32,14,44100 -i alsa,hw:0 -f:32,1,44100 -o t1.wav
-a:t6 -f:32,14,44100 -i alsa,hw:0 -erc:6,1 -f:32,1,44100 -o t6.wav

Kai will probably answer this better, but I just wanted to try.
