Plugin Alliance - TBTECH Kirchhoff-EQ v1.7.0 VST, VST3, AAX x64

Equalizer will never be the same again. Kirchhoff-EQ is a superb 32-band parametric equalizer designed for mission-critical professional applications. It features exquisite sound quality, analog modeled curves, ultra-low distortion dynamics processing, 15 filter types (with smoothly variable shapes) and 32 vintage EQ types that emulate real devices.

Highest sound quality:

Thanks to the “Robust Nyquist-matched Transform”, the Kirchhoff-EQ has made its digital frequency response closer to the analog one, without the high-frequency “cramps” that occur in conventional IIR (infinite impulse response) equalizers.

High-precision processing:

By default, the Kirchhoff-EQ works in 64-bit mode, but in order for the internal processing precision to reach 117 bits, a technique called “Double-Double” is used! It is the first equalizer in the world to achieve such precision. A technology called “Psychoacoustic Adaptive Filter Topologies” allows the filter structures to intelligently change themselves to a state of “best match”, which leads to optimized sound quality without compromise in low or high frequencies.

A Complete Palette of Analog and Digital Filter Types:

Kirchhoff-EQ includes 15 unique filter types, ranging from the usual low-pass, high-pass, bell and shelving to the more esoteric flat slope, flat top and sword filters. Take advantage of 9 carefully selected vintage EQ models and fully variable EQ points not found in the analog domain.

Selectable Phase Modes:

To accommodate all your phase relationship needs, Kirchhoff-EQ’s phase mode switches between zero-latency mode, analog mode, linear phase mode and the original mixed phase mode, which uses zero-latency when the band’s frequency point is low and uses linear phase when it is high.

Deep and Powerful Dynamic EQ Capabilities:

Kirchhoff-EQ’s dynamics handling isn’t just a bonus, it’s some of the richest dynamics capabilities you’ve ever seen. With dual thresholds, adjustable “onset” control, and a relative definition option, you can do what other EQs simply can’t: Simultaneously compress and expand to help “stabilize” a given frequency. EQ transients separately from the body. Or effectively connect one frequency band to dynamic activity in another. Even vintage-modeled curves can be applied to the dynamics processing.

Endless possibilities and intuitive operation:

Kirchhoff-EQ has every feature imaginable in an EQ, including spectrum capture, oversampling, lookahead, mid processing and monitoring, stereo width, global EQ scaling, and more, all optimized for ultra-low CPU load.

Optimizations:

Improved performance on touchscreens.
New vector font.
New pitch display in spectrum capture mode.
Default filter types created by dragging on low and high frequencies are now customizable.
Optimized Tilt editing section.
Optimized behavior of some popup windows.
Completely redesigned settings menu.
New ‘Factory Reset Default State’ button in settings menu.
‘Initialize’ now renamed to more accurate ‘Clear All Bands’; new ‘Reset to Default’ function.

Bug Fixes:

Fixed an issue where the render thread would hang in some cases.
Fixed an issue where a corrupted default state file could disable the plugin.
All knobs and sliders now respond to the ‘reverse mouse wheel’ setting.
Operations with the Lookahead switch, Output Gain knob, and Output Pan knob can now be correctly undo/redo or saved between A/B switches.
Fixed an audio glitch that could occur after adjusting band pan in non-minimum phase modes.
Fixed an issue where the frequency range would not change with the Q value when monitoring certain band types.
Fixed an issue where deleting tracks or plugins in a DAW in fullscreen could cause a crash.
Fixed several display issues in fullscreen.
Fixed an issue where fullscreen would not appear on top in some DAWs.
Fixed menus and popups scaling incorrectly with certain display settings.
Fixed incorrect mouse behavior when dragging knobs with certain screen resolutions.
Fixed an issue where the actual cursor position might not match the position the plugin responded to when used on multiple screens with different display scales.
Fixed an incorrect spectrum refresh rate in some special cases.
Fixed multiple issues in the Rosetta translation environment on macOS.
