Hmm...
- -f:bits,ch,rate sets set the "requested format"
- if the file exists (as it did in the case of mono2.wav),
ecasound will use the format of that file, possible
ignoring the requested format
- if -x is set (truncate outputs), ecasound will overwrite
the output file and not consider its format
The -X option (do not truncate) does not refer to appending, but instead
to updating (you can both append to the file and/or overwrite selected
parts of it).
