Here it is:

   http://www.ai.sri.com/ajh/audio/resamp-test-3/

The file make-test-files.csh is a script that uses ecasound and a ladspa
plugin to make a couple of sine wave files at 96k samples/sec and then
resamples them to 48k and 44k samples/sec. using ecasound and
sndfile-resample.

src-diff-32.csh src-diff-16.csh use od and awk to compare the pairs of
32-bit and 16-bit conversions, respectively. The results are in

  eca-src-diff1644.txt
  eca-src-diff1648.txt
  eca-src-diff3244.txt
  eca-src-diff3248.txt

As you can see the results differ by at most 1 LSB. No evidence of clicks.
Thanks Kai!
