I don't know about Reasampler, but I imagine it could with some work.
You might want to consider converting your input data into a function that it continuos, so you can sample it like:
Code:
function getSample(x) {
//Do interpolation here
return y;
}
and use interpolation (something better than linear) to fill in the gaps between sample points.
then you can loop over it to populate a fixed rate buffer:
Code:
for(var i; i<buffer_length;++i) {
buffer[i] = getSample( i * timeStep );
}
If you want to go more deeply into it, the top answer
here provides an algorithm to create a perfect reconstruction.
