Hi Nishant,

I love ecasound being so capable. One weakness is that the
command syntax does only what you ask for, not what you
intend.

If you want a lightweight method for recording using JACK,
and you don't mind using Perl, you may like to try Nama,
which provides a user-friendly (or at least user-friendlier)
layer to issue commands to ecasound.

nama> add-track foo1; source 1; rec
nama> add-track foo2; source 2; rec
nama> start
nama> stop

Of course there are a few configuration related wrinkles.
If you start Nama as

% nama -p

all files should appear in the current directory, but
this option hasn't been tested for a while.

Have fun!
