this is a feature/bug of ecasound: unless you specify the audio format
explicitly (with -f:bits,channels,srate,ileave-or-not) for each audio
object, the default params will be used (-f:16,2,44100,i).

But, but, in some cases ecasound recognizes some special cases (like a
chainsetup with exactly one input and one output), and tries to be clever:
use audio format of input in creating the output. Unfortunately, when
ecasound opens 'output.wav', it has not yet parsed the ewf-header and thus
does not yet know that '1.ewf' in fact will produce only one channel. And
in the end, the default audio params (-f:16,2,44100,i) will be used to
create 'output.wav'.
