Kirchhoff-EQ is the final word 32-band parametric equalizer designed for all vital skilled functions. It options improved sound high quality according to analog curves, 15 easily formed filter varieties, and 32 basic EQ varieties modeled from actual gadgets. The built-in dynamics processing capabilities are very versatile and have ultra-low distortion. All of this pushes the Kirchhoff-EQ to the following era commonplace. Equalizers won’t ever be the identical once more.
Options Kirchhoff EQ
▬ Strong Nyquist Matched Conversion –
With the initially developed “Strong Nyquist Matched Conversion”, Kirchhoff-EQ has made the frequency response within the digital area nearer to its analog counterparts with out the excessive frequency limitations of standard IIR (infinite impulse response) equalizers. This technique applies to all filter varieties in Kirchhoff-EQ.
▬ Excessive precision processing –
64-bit model is obligatory and non-negotiable. Kirchhoff-EQ’s inside processing is at all times performed in 64-bit (or 117-bit) format, whatever the host’s present DAW precision.
Topologies of psychoacoustic adaptive filters
All line filter constructions ought to have the identical sound on paper. Nonetheless, in actual functions, rounding errors trigger every filter construction to sound completely different: some are higher at low frequencies, some are higher at excessive frequencies.
A know-how referred to as “Psychoacoustic Adaptive Filter Topologies” has been deployed at Kirchhoff-EQ. The filter constructions transfer right into a “greatest match” state with corresponding band frequency adjustments, leading to optimized sound high quality at each high and low frequencies.
▬ Switchable extremely excessive 117-bit processing –
Since there are already 64-bit variations, why not go additional? Kirchhoff-EQ makes use of a method referred to as “Double-Double” to attain 117-bit inside processing accuracy! That is the primary equalizer on this planet to attain such accuracy. You may swap between 64-bit and 117-bit at any time. It would fulfill probably the most demanding ears.
* Linear part at all times makes use of 64 bits as a result of it’s a FIR (finite impulse response) filter and doesn’t assist 117 bits.
▬ Filter varieties –
15 distinctive filter varieties
low-pass, high-pass, bandpass: stepless adjustment from 0 dB/octave to 96 dB/octave;
name, notch: stepless adjustment from 12 dB / octave to 96 dB / octave;
low shelf, excessive shelf, sloping shelf: infinitely adjustable from 6 dB/octave to 96 dB/octave;
flat slope and flat prime;
sword: has a sharper slope than a bell, particularly designed to “dig out” resonances.
backside brick wall go, higher brick wall go, low allpass and excessive allpass.
▬ Infinitely Variable Slopes Filters –
The slope of most kinds of filters may be constantly adjusted from 0 dB/octave, 6 dB/octave or 12 dB/octave to 96 dB/octave. Would you prefer to attempt the 8.125 dB/oct excessive go filter?
32 filter varieties modeled after historic classic EQs!
Get classic and trendy on the identical time! We modeled 9 classic {hardware} EQ blocks, totaling 32 EQ varieties applied in Kirchhoff-EQ. Profit from strong Nyquist conversion: every EQ kind matches the supply tools precisely and won’t compress close to the Nyquist frequency. As a subsequent step, in contrast to the unique {hardware} which solely permits you to select between a couple of frequency positions, we’ve modified the DSP mannequin to make adjustable frequency factors for all of those varieties! Every kind in these fashions can be utilized with common EQ varieties or different modeled varieties, and can be used with dynamic capabilities (besides bass and treble varieties). This provides you extra freedom and comfort to work.
*Nonlinear conduct not simulated. All kinds of classic filters comprise solely the best linear elements of their bodily mannequin.
▬ Zero-Latency/Analog/Linear/Blended-Section Modes –
Kirchhoff-EQ’s part mode may be switched between zero-latency mode, analog mode, linear part mode, and blended part mode to fulfill all of your part relationship wants.
* No matter which part mode is at the moment in use, if dynamic options are enabled for a filter band, it can function in minimal part mode (won’t have an effect on different bands).
▬ Blended part mode –
Zero latency and linear part modes sound very completely different. Kirchhoff-EQ gives a blended mode that makes use of zero delay when the bandwidth level is low and makes use of linear part when it’s excessive. Every band can easily swap between minimal and linear part in line with their frequency.
* There isn’t any noticeable crossover between filter varieties, whereas in blended part mode the transition is clean.
▬ Versatile dynamic EQ capabilities –
The dynamic options within the Kirchhoff-EQ usually are not only a bonus, they supply the richest options you’ve ever seen. Lets you obtain the limitless potentialities of dynamic EQ capabilities. All kinds of filters (besides low-pass/high-pass, bandpass and notch), even these classic ones, can be utilized with dynamic capabilities.
▬ Harmonic Shift Envelope –
All dynamic EQs have odd and non-integer harmonics, these are the legal guidelines of physics. Utilizing superior DSP strategies, Kirchhoff-EQ now “shifts” a lot of the power from odd harmonics into even harmonics, creating ultra-low noise and enhancing the sound. Now you possibly can freely use the dynamic options with out worrying about ruining your sounds.
▬Reversible Threshold –
Now you can concurrently management how the audio system reply to the portion of the sign above/beneath the edge. Within the Kirchhoff-EQ, the Excessive stage works as a compressor or upstream expander, and the Down stage works as an expander or upstream compressor. For instance, you possibly can enhance the sign beneath the edge AND compress the sign above the edge to “stabilize” the band.
▬ Relative envelope detection/detection –
Let’s think about a easy case: we’re enjoying an audio clip the place sounds round 1kHz are 9dB. You is likely to be pondering, “The 1kHz band is overloaded, we should always lower it all the way down to 1kHz.” However we should additionally think about the general stage. If the entire sound is 30dB you received’t really feel like 1kHz is an excessive amount of, as a substitute you would possibly really feel prefer it’s not sufficient. One of the best criterion for figuring out whether or not a band’s loudness is excessive or low is its relative contribution to the general loudness envelope, not simply its absolute dB worth.
So in Kirchhoff-EQ we introduce “Relative Envelope Detection/Detection”. Dynamics is affected by each the present bandwidth and the relative portion of the “relative” bandwidth. The contribution of Relative Envelope Detection to dynamics can also be configurable: when set to 0%, it degrades like a traditional dynamic EQ; and with a price of 100%, the quantity of dynamics is totally calculated from the relative share.
The “detect” band is about in line with the frequency and Q issue of the default band, “Relative” is the complete sound envelope by default. However they are often put in freely.
Detection bandwidth and relative bandwidth have freely adjustable frequency level and Q worth. Or activate “SC” mode to make use of “Detection” or “Relative” with aspect chain sign.
▬Onset Detection Combine –
When the Onsets combine is enabled, the envelope detector reacts extra particularly to transients throughout the envelope. This fashion you possibly can fine-tune the tone of the transients. For higher customization, you possibly can “combine” the envelope detector and the beginning detector. For instance, you possibly can compress the excessive frequencies a bit, whereas compressing the sharp rise within the excessive frequencies extra aggressively.
With the initially developed “Strong Nyquist Matched Conversion”, Kirchhoff-EQ has made the frequency response within the digital area nearer to its analog counterparts with out the excessive frequency limitations of standard IIR (infinite impulse response) equalizers.
