When Spice loads the libsndfile component, can the component find out
the inter-sample period used by Spice?
no. Spice does not use a constant interval; else it would be straight
forward to use libsamplerate.
If the above is not possible, I suggest that you up sample the audio
by say 128 times and then linearly interpolate to get whatever inter
sample values you need.
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..
Since you're patching ngspice anyway, maybe introducing a fixed-timestep
behavior into ngspice is easier? IMHO it's the 'correct' solution (cfr
other mails).
