Naive LPF is a resonant low/high-pass filter plug-in VST effect for Windows with a very convincing, classic sound. Naive LPF features a separate envelope follower for each of 6 channels and full automation, MIDI CC and even joystick control of all parameters.
This filter has been developed to closely model the way some real world analog circuits work, as opposed to some other techniques which, while well adapted to the math processing power of a computer, just don’t seem to render the same organic feel.
Not to say that those techniques aren’t just as valid in some applications, but this particular effect was designed to provide “analog feel” at the expense of a bit more processing power. This was not intended to be a “clean” or “transparent” filter by any means. Really, at this point in its development it should be called the “Not-So-Naive LPF” because it’s actually quite a sophisticated and useful implementation.
