    Good to see that still no one has figured out the secret.

    Fascinating. I'll read that before bed. No sarcasm either.

    I'm kinda of the opinion that someone actually did. Someone named Cliff has a pretty good take on this whole modeling thingamabob. You should check out his work sometime. ;)

    Nice to see it was neither posted nor written by "MikeLand".

    or at least those 2 guys haven't...

    I doubt there is one secret anyway... :) there is usually more than one way to skin the cat....

    Nice article. Looks to be well researched and includes references from our own Randall Aiken.:aok


    Now where have I seen comments like these before? :huh :D


    Owing to the complex dynamical
    nonlinearities of the tube-amplifier circuit, true
    physics-based models for accurate real-time simulation
    of the tube amplifier have yet to be discovered.
    It must be noted that owing to the essentially
    nonlinear, complex nature of tube amplifiers, objective
    evaluation of their sound quality—and hence
    the sound quality of tube emulators—is extremely
    difficult.

    Although some tube-amplifier enthusiasts
    might feel that digital emulation is a threat to the
    tube-amplifier industry, the authors believe that it
    should rather be viewed as an homage. It can also be
    seen as a form of conservation, because the quantity
    and quality of available tube-amplifier components
    continues to dwindle. After all, the ultimate goal
    of amplifier emulation is to convincingly reproduce
    all the fine details and nuances of the vacuum-tube
    sound, and to make it widely available for use in
    artistic expression.

    I noticed your name in the references as well.. I wondered if you knew you had been referenced or not.

    Very cool. I've been looking for something like this for a long time. Cheers.

    Actually, the technical content of this paper was dramatically simplified, and it needed to be, for the audience of the targeted publication. Had this been written with an Engineering or Scientific publication in mind, it would not have been comprehensible to readers not trained in DSP. It's actually sort of hard to translate DSP into plain language, especially for graduate students (IMO and experience), so I think Kudos are due to the authors for their simplified explanations: pretty lucid me thinks. Enjoy

    I thought it was pretty good and well-targeted for the intended audience, too. I'd love to see an in-depth treatment of the subject, complete with algorithms and examples, something like the papers in "Applications of Digital Signal Processing to Audio and Acoustics", by Kahrs and Brandenburg.
