My tests indicate that the clicking problem was fixed in this snapshot:

 http://ecasound.seul.org/download/snapshots/ecasound-2.3.6-cvs-20041221.tar.
gz

Besides listening, I used od to compare the files produced by the two
programs (ecasound and sndfile-resample, the example program that is part
of libsamplerate) with my test sine-waves and found that at 16-bit word
length the results are identical and at 32-bit word length they differ at
most by 1 LSB.

I also observed that files produced by ecasound are epsilon shorter (like
50 to 200 bytes) than those produced by sndfile-resample. I haven't had
the time to figure out way, but this is pretty insignificant as far as I'm
concerned.

I'll post a pointer to my test files when I get a chance.

Thanks for fixing this Kai....
