quote of the day

IMHO, its not about randomness (noise) in components at all. Its about the (very short) memory some circuits can deploy, depending on the overall load of the system. The shortcoming of the component modelling approach is still that the whole modeled system is deterministic (which is not). – bootsy


  1. Having Thrillseeker as an testing unit now, i think you are right… This is the way to go… IMHO..

    Thanks so much for everything Bootsy… Namaste..

  2. So what you are modelling is the phase response of analogue components at different points in their operating range? Isn’t that just a function of lead and lag of the components? I agree that inductors have hysteresis and that active components have extreme phase responses in saturation, but it surprises me that detailed circuit modelling doesn’t already take this into account. If it doesn’t, then you are onto something here. You may have noticed the model approximations (i.e. that phase response is actually not linear) and taken into account some very real details of real world analogue components. Cool.

  3. This remember me something.
    When ppl do extreme car audio, they use 1 to 10 Farads caps (yes, FULL Farad, not micro or pico farad) before their amps.
    Like : http://www.sebastoautoradio.net/famille-83-CONDENSATEURS.html
    Because when there is a massive bass or kick, it drain all the electrical power (bass freq use a lot more energy than all the rest).
    And of course, this massive drain can destroy the system or just sound very weak without caps.
    This bass energy drain can alter all the other frequencies, like a pumping compressor.
    And it is not “deterministic” at all.

    I think this word “deterministic” is the biggest error in audio simulation.Once you introduce memory effects, randomness and such things, sound become more “alive”.

    And i love Nebula too, because it capture more than what ppl can even think to model 😀
    That’s the biggest difference between simulation and capture.
