Hi,
I read on spicy sound website: "However todays computing power allows to
do so almost in real-time!"... do you think you'll get it real-time?
no,
not any more.
Without oversampling, small circuits run /almost/ in real-time. However
the posted 3 seconds of guitar took almost 4 mins to be processed with
ngSpice simulating at 1s/(64*48k) timesteps.
4 mins? OMG! :-\
indeed - at least it scales linearly with decreasing timesteps ;) - for
guitar a *8 or *16 oversampling is sufficient. ngSpice is clearly is not
suitable to be used as audio-effect; yet it's handy to test&debug
audio-circuits, or even create convolution samples.
Oh well, I didn't notice the 64! :-D
Anyway, keep it up. It's very interesting stuff!
