Hello again,
I've added libsamplerate for resampling/oversampling which - as expected
- dramatically improves the quality of the ngspice processed sound.
Here's some example 3sec guitar sound from current testing:

(left channel: resampled input-sound, right channel: fuzz-effect out)
http://mir.dnsalias.com/oss/spicesound/examples#audio_example
The fuzz effect still sounds a little odd, but I believe that a
DI-recording would sound just like that ;) - I have not progressed to
simulating tube-amps or synths yet.. lack of time, netlists and
tube-models; it's low priority ATM.
