Thanks!
I'm working on a VST electronic circuit simulator and this link seems to be useful.
Earlier I had been soldering and repairing real electronic things like TVsets, cassete players, distortions and tube amplifiers for almost 10 years, and 2 years of electronic circuit theory at the university, and I want to make some use of this experience in VST development.
This applet uses the same technology as in Spice (it's open source too, and it's written in C) - stamping circuit elements into a matrix and solving it using Crout decomposition.
I made GUI, and algorithm for solving circuit voltages and currents of the static circuit, but not tried yet to make it realtime..
Not sure if the today's computers are able to make so many computations at sampling rate, and it seems to me that to make it more analog sampling rate should be much higher than 44100 Hz.
I'd like to try to emulate some of my selfmade distortion stomps - would they be equal..

Yes, I'm going to release it this winter. It's in a very early stage, I'm planning to make many optimizations, debugging and insert some features like wav loading/exporting,(unfortunately I'm very busy at work now.. Can't wait I could finish stable version of it!). Since the main aim of this project is not circuit analyzing but sound processing - it will include only needed tools.

nice! i'm looking forward to that, too. maybe with that, i can finally learn a bit about circuit modelingI'm working on a VST electronic circuit simulator
open source for the win! <3it's open source too

Intrigued. I think I seen recently that the Falstad applet can do some form of audio processing, output to wav. Maybe wrong but I’m sure I seen that somewhere recently. May be worth a look?

Oh yeah, it’s discussed here - https://www.google.co.uk/amp/s/amp.redd ... ith_audio/
