March 15th 2022 | Kirchhoff-EQ VST2, VST3, AU, AAX Native,ARM |150 MBULTIMATE EQ PLUGIN WITH SUPERB DYNAMIC PROCESSING AND VINTAGE MODELS
Kirchhoff-EQ is an ultimate 32-band parametric EQ plugin built for all critical professional applications. It has refined sound quality, analogue-matched curves, 15 filter types with continuously variable shape and 32 vintage EQ types modelled from realworld devices. The builtin dynamic processing functions are highly flexible and have ultra-low distorsion. All these push Kirchhoff-EQ to a next-generation standard.
Equalizers will never be the same again.
Ultimate Sound Quality
Robust Nyquist-matched Transform
Through originally developed "Robust Nyquist-matched Transform", Kirchhoff-EQ has made digital-domain frequency response more approximate to its analogue counterparts without high frequency cramping as in regular IIR(infinite impulse response) equalizers. This technique is applied on all filter types in Kirchhoff-EQ.
High-Precision Processing
64-bits is mandatory and it's not negotiable. The internal processing of Kirchhoff-EQ is always in 64-bits (or 117-bits), regardless host DAW's current working precision.
Psychoacoustic Adaptive Filter Topologies
All linear filter structures should have same sound on paper. However in real-world application, round-off errors make every filter structure sound differently: some better in low frequency, some better in high frequency.
A technology called "Psychoacoustic Adaptive Filter Topologies" has been deployed in Kirchhoff-EQ. Filter structures change themselves to a "best fitting" state along with corresponding band frequency changes, making optimized sound quality in both low and high frequency.
Filter Types
15 Unique Filter Types
low pass, high pass, band pass: continuously variable from 0 dB/oct to 96 dB/oct;
bell, notch: continuously variable from 12 dB/oct to 96 dB/oct;
low shelf, high shelf, tilt shelf: continuously variable from 6 dB/oct to 96 dB/oct;
flat tilt and flat top;
sword: has sharper slope than bell, specifically designed to "dig" out resonances.
brickwall low pass, brickwall high pass, allpass low and allpass high.
32 Filter Types Modeled from Historic Vintage EQs!
Get vintage and modern at same time! We modeled 9 vintage EQ hardware units into Kirchhoff-EQ, in total of 32 EQ types. Benefit from Robust Nyquist-Matched Transform, every EQ type precisely matches the original hardware and won't cramp near Nyquist frequency. For a further step, unlike the original hardware that only allows to choose between several frequency positions, we modified the DSP model to make adjustable frequency points for all these types! Every type in these models can be used together with regular EQ types or other modeled types, and can be applied with dynamic functions (except lowpass and highpass types). This brings you more freedom and convenient operations.
