no. Spice does not use a constant interval; else it would be straight
forward to use libsamplerate.

sounds like a great idea.

I should do that with the output too, but it's a little more complex
there: In the beginning I've tried to take the average for all the
"spice"-samples matching the corresponding audio-sample. I've only tried
that up to 1/(4*Fsample) and it gave much worse results than just taking
the closest sample...  - combining interpolation and resampling could be
the solution.

now that I've got the framework, I'll dig into the details..
