I noticed that if I write to a file, then (while ecasound is still
running... in interactive mode obviously), I do ecalength on the file, I
will get a differnet length than when I close out ecasound and do
ecalength again.

See if you get the same results. Write to the file in interactive
mode... then do...

if it says 'finished', then keep ecasound running and do ecalength on
the written file.

Then close out ecasound and do ecalength on the file now. Are the
results (the lengths) different?
