I haven't looked at the code for zita-resampler but for libsamplerate,
what you said above, is not correct.
Sepcifically :
a) The API has an src_ratio field which is of type double floating
point. Thats how you chose your resampling ratio.
b) Internally, the time distance between samples is also calcutated
in double floating point.
The only place integers are used for time offsets is in the calculation
of the indices into the filter table and the interpolation between two
adjacent values in the table.
