I've been dreaming about a /jackifiying/ spice ;) - I spiced up my Pfingst Montag by added a libsndfile voltage-source to ng-spice. - For simple circuits it's not too far-off real-time performance: it takes about 4 seconds to simulate 1 second of foxxtone at 48ksps over here. Now it's Tueday and using a IR seems the way to go... simulating the foxx effect alone is not trivial. Based on the posted schematics, here's a preliminary http://mir.dnsalias.com/_media/wiki/foxx.oregano.gz - try yourself.. > the good news about doing this though is that you don't have to > (unless you want to) emulate everything about the circuit, just the > signal path. this would simplify and speed up the calculations > somewhat. I've started to document the spice patch at http://mir.dnsalias.com/wiki/spicesound - the code's barely a few hours old and highly experimental. NTL, it's already allows to process spice3 netlists reading and generating wav file(s). robin PS. pure-data is more fun than this! _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-user
