Well, I guess there is more than a single way to solve this problem
and that some might come up with more efficient ones
(command-line-wise) than mine, but here it is:
You want to use the -y and -t options to split your big file; it
requires you to find out how long you want each track to be before
going ahead. Suppose a 15 minutes recording that you would want to
divide into three 5 minutes tracks:
# ecasound -b:512 -c -f:16,2,44100 \
-a:1,2,3 -i:whole.wav \
-a:1 -t:300 -o:track1.wav \
-a:2 -y:301 -t:300 -o:track2.wav \
-a:3 -y:601 -o:track3.wav

Hope this helps,
