to be honest, it isn't really pretty but sounds really good.
Luftikus is a digital adaption to an analog EQ with fext half-octave bands and additional high frequency boost. As an improvement to the hardware it allows deeper cuts and supports a keep-gain mode where overall gain changes are avoided.
Bands and Shelves
Luftikus has half-octave bands at 10, 40, 160 and 640 Hz, completed by a high shelf at 2.5 kHz. For adding sparkle to recordings a further high frequency boost at 2.5, 5, 10, 20 and 40 kHz can be used. The overall design was improved to allow deeper cuts. The range -5 to +10 is the original range while below -5 results in cuts unavailable in hardware.
The hardware adds overall gain which can lead to clipping. To counter this an output trim as well as the "Keep Gain" mode is available. While the trim allows manual adjustments the "Keep Gain" mode will keep (more or less) the overall loudness by reducing gain in non-boosted areas.
The "Analog" mode models a more analog behavior while in "Mastering" the controls become stepped and the "Analog" mode performs better.
This EQ is very good. It just fixed a vocal that's been driving me crazy. This is totally worth having. I compared it to MaagEQ which I own and actually preferred luftikus on this particular track. I was fiddling with the pitch plug. It's nice but some of the controls don't do what you think they're going to do. For example, the filter seems to control delay time or feedback in some cases. I'm using the AUs on Mac. Maybe I'll try the VST.
Doing a comparison with the Maag and for some reason the 40k setting on this one seems to have way more in common with the 20k on the Maag. Sounds very good though but at least on this setting they are not comparable. This kind of reminds me of the PQ-33 that imitated the Portico. It gets close but not quite. That said, it's free! I can however see where this guy would be used over the Maag. It's a little more aggressive so that tonal difference could come in handy. Good plug
