I haven't looked at the code for zita-resampler but for libsamplerate,
what you said above, is not correct.
It /is/ true for zita-resampler:
Libzita-resampler does not provide dynamically variable
resampling ratios, and requires the ratio F_out / F_in
to be ≤ 16 and reducible to the form b / a with a,
b integer, and b ≤ 1000. This includes all th
e 'standard' ratios, e.g. 96000 / 44100 = 320 / 147.[1]
Elsewhere, I think it's also stated that the intended
purpose was high-performance conversion between standard
audio sampling rates.
