I've been trying to reproduce this but with no success so far (with the
same version of libsamplerate). Could you provide me with an example of
the low-freq crackling? And if possible, by using a generated source (so
that I can reproduce all the steps):

# with git version (5secs of sine as input)
ecasound -f:16,1,96000 -i tone,sine,440,5 -o foo96000.wav
ecasound -f:16,1,44100 -i resample,auto,foo96000.wav -o foo44100.wav

# or with older versions (with LADSPA)
ecasound -f:16,1,96000 -i null -o foo96000.wav -el:sine_fcac,440,1 -t:5
ecasound -f:16,1,44100 -i resample,auto,foo96000.wav -o foo44100.wav
