Softube Vintage Amp Room v2.5.9 WiN

What they discovered is something most engineers already know intuitively: that what the human hearing system perceives doesn't always relate directly to the numbers measured by the test gear.
Some parameters are vitally important to the subjective interpretation of a sound, while others are much less relevant, so Softube seem to have concentrated their efforts on those aspects of distortion that the ear finds important. Along the way they developed a circuit-modelling approach in which every component is individually modelled, that includes an algorithmic method of modelling non-linear devices such as amplifier tubes. They also used Infinite Impulse Response filters (IIRs) to model the resonances of speaker cabinets, microphones and rooms.
