Yup, whitespace, and order of arguments, do matter. :)

Fellow lau-subscribers, I promise this is last post from me today. :) For 
very specific ecasound questions, I recommend continuing the discussion on 
ecasound-list mailing list (see eca.cx website for info).

As there can be multiple input and output files (and devices), there is 
no direct relation between the input and output file formats in the 
special case that there happens to be exactly one input and output. Unless 
you specify the format with "-f" option, ecasound will use default params 
(-f:16,2,44100 ... can be redefined in ~/ecasound/.ecasoundrc - see man 
ecasoundrc(5)) when creating new files.

Special-purpose frontends such as ecaplay usually behave differently 
(i.e. similar to aplay, sox, etc) - the output is opened with audio format 
taken from the input file.
