I recently discovered that this works (if you're using wav files at least):

cat f*.wav | ecasound -i stdin -o concat.wav

Your problem seems to be that you're really mixing the files,
and not concatenating. I guess ecasound divides the signal by the number
of files you have. WHich reminds me that I once really wanted
to write a soundfile cat tool.
