that's good to know!
unfortunately, both zita-resampler and

the sample rate ratio internally as a fraction of two integers,
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.
i found that. but when i'm trying with sndfile-resample (using the -by
parameter), i get an integer target sample rate (or at least, that's
what the output claims), which is what confused me. plus it seems that
the target sample rate in the SRC structure is an int, not a double, so
i don't understand how arbitrary ratios could be represented...
b) Internally, the time distance between samples is
also calcutated
in double floating point.
great. so it looks like a minor hack to sndfile-resample to get what i want.
best,
