I have a feeling some people are allergic to solving basic sets of linear equations? The math behind it is about as basic as it gets, it is literally a set of simultaneous linear equations, the kind of stuff that is covered in high school! Things get more interesting when you need to solve non-linear components. As for tubes, I think more research is needed to accurately characterise the time varying behaviour of tubes, but even existing empirical models like the one proposed by Koren would probably be enough for audio work. The more challenging part I feel would be in the electro mechanical power amp + speaker stage, where you have more complicated interactions between non-linear semi-rigid bodies coupled to the circuit via an electric field with coils and magnets. -- dupswapdrop -- the music-dsp mailing list and website: subscription info, FAQ, source code archive, list archive, book reviews, dsp links http://music.columbia.edu/cmc/music-dsp http://music.columbia.edu/mailman/listinfo/music-dsp
