[sdiy] Analog Modeling, with a computer!

It was 44.1 Khz, stereo. Probably overkill for the frequency response of the spring reverb. And, yeah, I got the "plop." That's the dispersion for you. Without the dispersion, a spring reverb is a ridiculously simple algorithm - just a few parallel waveguides.

I did a spring reverb emulation last summer at a Banff workshop, using a few hundred cascaded first-order allpass stages to simulate the dispersion of the spring. It sounded great, and only took up70% of a 2.66 GHz Pentium 4! 

  I'm very curious: did you get anything above 8 kHz using all that horsepower?? Or would that be cheating? And did you get a big wet 'plop' at the attack of a sound?
