Re: [LAD] simulating analog audio devices part II
I have not progressed to simulating tube-amps or synths yet.. lack of time, netlists and tube-models; it's low priority ATM. i don't mind making the circuits (in oregano or whatever), but i don't have decent models of tubes or transformers, and am not sure how to easily work with them in oregano (it's been a while, be kind)... i do however have access to a lot of classic amp schematics (fender, marshall, vox etc) and don't mind spending time capturing them into oregano etc if it will help. porl ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-dev

Oh well, I didn't notice the 64! :-D Anyway, keep it up. It's very interesting stuff!

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. Does anyone here have access to the full version of http://www.acusticaudio.com/modules.php?name=Products&file=nebula2free VST plugin? - It would be interesting to know if ngSpice-snd samples can be used to program it. nudged by Erik at http://linuxaudio.org/pipermail/linux-audio-user/2007-May/045899.html I've Taylor-expanded a convolution integral, and started to look for some papers. The maths is not too wicked after all; but coding a volterra transfer function best with CPU optimization is no laughing matter.. - I've chatted with a physicist friend who has access to some pro-maths software to crunch integrals and product series and experience doing so - I'm gonna spend a few weeks with Florian during the summer and 'll get back to you guys. ATM my ToDo list is way too overloaded and just glimpsing at bruteFIR or aliki: this is no small project either! robin ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-dev

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. robin ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-dev
